How to Make Eggshell Calcium (and Why You'd Want to)

Photo of homemade eggshell calcium DIY project

Calcium is the most abundant mineral in our body.

While most of our calcium resides in our bones and teeth, it’s also important for muscle contraction, nerve health, enzyme activity and cell formation.

In fact, our bodies need ample, daily amounts of calcium… and if we don’t get what we need, our bodies have no problem pulling excess stores from our teeth and bones.

So, let’s just say we want to be sure we’re consuming PLENTY of calcium, especially if we are a pregnant or nursing mama!

I do best consuming ~ 2,000mg of calcium a day.

I feel the most calm and balanced and don’t suffer from muscle soreness or body stiffness. High-quality organic, and preferably raw, dairy products are phenomenal sources of calcium as are bone broths, fish bones, and even almonds.But since I would need to drink 2 quarts of milk to hit this quota, I sometime rely on a calcium supplement, especially when I’m nursing or pregnant.

Which one to chose? Calcium citrate? Hydroxide? Gluconate? Aspartate? Or Coral Calcium? And, I could go on!

But as natural mamas, we know that the best source is FOOD since it’s the mostly easily accessible for the body.

Did you know that eggshells are a great, inexpensive, natural source of calcium?

Yes, EGGSHELL Calcium!

High-quality eggshells contain 27 essential microelements but they’re mostly composed of calcium carbonate, a form and structure that’s very similar to our bones and teeth.

In animal and human tests, eggshell calcium shows increased bone density, less arthritic pain, and even stimulates cartilage growth. You can read more about it here.

Sounds great, huh? And it’s really easy to make.

Ingredients and equipment:

  • 1 carton of organic pastured chicken eggs
    If you can get fresh from the farm, even better and try to get eggs from chickens that don’t eat soy. Pay the extra price since this will serve as a supplement and is much cheaper than buying calcium tablets. Confused how to find or know if eggs are good quality? Here’s a tip… the thicker the shell, the more nutrients. I don’t have a good source close to where I live, so I order mine from Tropical Traditions and their farms in Wisconsin. I love theirs because they are SOY-FREE, something very hard to find in store bought, even organic eggs.

You will also need:

Directions

  • Use up your eggs as you normally would, keeping the shell in the carton to make your supplement
  • When you have your dozen shells, rinse them well in water. Remove any whites that might be stuck but don’t remove membrane as these have extra nutrients.
  • Fill a stock pot with approximately 6 cups of filtered water and bring to a boil.
  • Carefully put your eggshells into water. (This will kill any harmful pathogens)
  • Let cook for 10 minutes.
  • Drain shells.
  • Spread the shells on glass or stainless steel baking sheet and let dry overnight. In the morning, put in a 200 degree (Fahrenheit) oven for about 10 minutes to completely dry out.
  • Once completed, put a few shells into a coffee grinder and run until they are pulverized into a granular form. Continue until all of your shells are powder.
  • Store in a tightly sealed Mason jar in the cupboard away from heat or moisture.

How to Consume Eggshell Calcium

1 tsp. contains approximately 800-1,000 mg. of calcium. Consume by mixing in a small amount of water with a meal. Consume 3/4 to 1 tsp daily, divided in 3 servings with meals. Don’t consumer more than 1 tsp a day as it can irritate sensitive digestive tracks.

ENJOY!

How about YOU? What’s YOUR favorite way to get calcium into your diet?

  1. Would using the shells of hard-boiled eggs make any difference?

  2. I recently discovered that I have a delayed immune response to egg whites and yolks, do you know if it is ok to supplement with egg shells?

      • Why not just encapsulate the powdered egg shells? I usually encapsulate everything I take. That way, there’s no taste to contend with.

  3. Am I right in assuming that I can just grind up my egg shell and consume it in a smoothie after I remove my boiled egg from it and the baking/drying process is only necessary if I intend to store ground shells?

    • I would like the answer to this too 😉

      • I have the same question about using shells from boiled eggs

  4. Hello! Thank you very much for your post. I would like to ask if it’s ok even for a 18 month child to consume 1 tbs of eggshell per day or it’s too much? We are fighting against cavities and would like to try this method too. Thank you for your answer!

    • if you are trying to fight cavities, i recommend ramiel nagel’s book on tooth decay. keeping them away from oatmeal and sugars and giving them a more traditional diet would help greatly.

      • Thanks, we are already doing it, but unfortunately it’s getting worst. I am really desperate, so I wanted to try something more. I cannot find any information about children consuming eggshell (it shouldn’t be harmful, isn’t it)?

        • Give them eggshell and make em rinse their teeth with comfrey root decoction

        • Are you giving them a bottle with fruit juice at bedtime?. If so, stop. It can cause Baby Bottle Syndrome. Decaying teeth that kiip getting worse. Hope this helps.

        • Some things we’ve also learned to eliminate are, chewable vitamin c (sugary and acidic), sweetened granola and dried fruit (sugary and sticky in the teeth), grains (deplete body of minerals) and then have added cod liver oil, raw grass fed milk and butter, organ meats (grass fed), iodine (read The Iodine Crisis) and swish vigorously after meals with a salt water.

          • Flossing the child’s teeth every night before bed and brushing twice daily dhould help. Any problems with acid reflux? Stomach acid causes decay rapidly in children.

        • Get that child started on oil pulling hon. Use coconut oil. Please do a little research on oil pulling. You can use different oils but I believe coconut oil (organic of course) Is most palatable and has the best benefits. I guarantee you will see major improvements. I also recommend coconut oil and a little baking soda instead of tooth paste. Add a drop of peppermint oil if needed.

        • I give my son eggshells in smoothies. He was five when I started doing this. I would have sooner, but I didn’t know about it. We drink Calcium bentonite clay also, for the minerals. I always eat butter or take coconut oil along with eggshells and clay.

    • Here is a list I created after researching how to prevent and heal cavities. So far my son has none, he is 6. I haven’t had any either. We do everything on this list. If you do not know what something is just google it.

      Teeth Health:

      Sunbathe a little each day

      Gelatin: drink in hot tea

      Collagen: drink in smoothies or milk

      Kefir

      Swish saliva

      Raw milk and raw cheese

      egg shells in smoothies

      Raw eggs in smoothies

      Cod liver oil
      Raw butter oil

      Butter in smoothies and tea

      bone broth

      Comfrey root tea: swish in mouth 20 minutes
      Horsetail tea- drink
      Oatgrass tea- drink
      White oak bark- drink

      Coconut oil and turmeric: brush teeth with

      Coconut oil: oil pull and eat/swallow

      Olive oil: eat/swallow

      Colloidal silver: swish

      Mineral drops salt lake Utah: add to water

      Sole: Himalayan pink salt in water

      Alfalfa powder

      Drink Calcium bentonite clay and swish in mouth

      Activated charcoal: whitens teeth, brush or swish

      Fulveric minerals: omica: add to water

      Morninga powder

      Chlorrela and spirulena tablets: swallow

      Cayenne, ginger, garlic for gums

      Eat raw carrot or celery: acts as toothbrush

      Cow Liver

      Red meats: grass-fed

      Eat Chicken with the skin

  5. I Love your website ! You are truly making a change in this world. I have referred so many to your site.

    About calcium, I buy eggs from a wonderful local farm. They are sustainable and above standards in meeting organic farming. The eggs are beautiful and I feel like I am back on my grandparent’s farm when I go there! I have been drying dozens of egg shells in a very bright picture window. Before I crack them I rinse and then after cracking I coat them with organic white vinegar keeping the whites in tact as much as possible.

    I have recently learned that there is an imbalance in nature when the intake of calcium is not in sinc with magnesium. If one partakes in calcium without magnesium it can cause Bigiminy heart arythmia. This happened to my mother, she had been taking calcium supplements for years for osteoporosis. We have learned that a 2 part magnesium to 1 part calcium is something to consider.
    This was from a Naturopath; however the Dr. said he had never heard of this. We did not disagree with him but rather decided to just eat foods with both of these nutrients. She was given betablockers and thank goodness is better and no longer taking them.

    I want to make bread and try using calcium eggshells, do you or anyone else know how I should do this? I can’t find any recipes.

    I know about Tropical Traditions it’s also a great company, I have ordered the butter, cheese, bison, and coconut oil, and wheat.
    Thank God for those that stayed the course in practicing the traditional farming methods I sure hope these paving the way will inspire more of us to steer clear of gmo methods.
    Thanks very much for all you do ! You are Great!

    • We just sprinkle the eggshells on top of yogurt or applesauce and call it “sprinkles”. It gives it a nice crunch like granola does

    • I’ve been using eggshell water for years on plants. I cook about 2 shells per quart of water. It is powerful. My favorite plant food.

      • How did your plants do with this ? Just excited about how it might help my plants. :)

        • I use it on my medical cannabis garden.

  6. I use an egg shell for quite a while now, but I found before that 5g (1 tsp) have about 400mg, according to ur post its twice more :-O I recently develop some stomach, intestine, I`m not even sure which exactly problem. Basically I keep burping after every food, drink, before and after sleep, I seem to have low stomach acid or digestive enzymes, I eat very healthy so it hits me,maybe I was doing sth wrong about those shells. I`m not seeking for advice, just someone opinion, as I believe more in a nutrition then the drug therapy .

  7. I’ve stored egg shells in a Ziploc baggy in my fridge for a couple months now and am about to make this. Are the shells still ok to use after having been sitting that long?

    • The boiling process will kill any harmful bacteria that may have grown during this period. There is no reduction in potency with aging of the shells.

  8. You need to mix the egg shell with an acid to make it more bioavailable. Calcium carbonate does not absorb very well.

    You have to add the egg shell to a pure citrus juice, like lemon or lime. It will bubble and chemically react, turning it into calcium citrate which is a bit more absorbable (about 20-25%).

    Vinegar is also useful. Combining apple cider vinegar with the egg shell turns it into calcium acetate, which breaks down in the stomach into free calcium ions and acetic acid, which helps the stomach digest the calcium.

    • I just jumped back onto this thread to try to get tips on how to get it down. Mine sticks to the glass when I try to stir in a tad of water and chug it. any other tips besides mixing it with ACV?

      • Mix 1/2 teaspoon powdered eggshells with 3 tablespoons of lemon juice. Let sit for 10 to 15 minutes. When the mixture is no longer sour, you can drink it. This has helped reduce my cravings for dairy.

    • Robert, do you have any more specifics on how to process the egg shells with the Apple Cider Vinegar? Ratio of shells to amount of vinegar, etc. I am very interested. please advise when you can. Do you then add it to water to drink or mix it with anything else? Is it better to just use it straight after it has dissolved?
      I’ll be looking forward to hearing from you!
      Thanks,
      DeeAnn

      • I have tried dissolving powdered eggshell in ACV and it didn’t dissolve so I threw it out.

    • What ratio would you use?

  9. Hi, thanks for this article! I was wondering if I could use quail eggshells together with chicken eggshells? Do they have the same calcium content?

    Thanks and God bless!

  10. How long does the grounded egg shell powder shelf life last for?

  11. Hi! I was wondering if I could use ground eggshells in a remineralizing toothpaste recipe in the place of calcium powder. I think I’ll give it a go, but wondered if it would have the same benefits. Thanks for any advice, and what a great tip. :)

    • Yes! Egg shell tooth powder helps my nails be strong yet flexible. I’ve used egg shell tooth powder over ten years.

  12. Hi! I was wondering if I could use ground eggshells in a remineralizing toothpaste recipe in the place of calcium powder. I think I’ll give it a go, but wondered if it would have the same benefits. Thanks for any advice, and what a great trip. :)

  13. I went Vegan a week ago. A month prior to doing this I had done my eggshells powder and was taking my daily dose calcium. Literally, 5 mins ago, I realized that the eggshells come from an egg, eggs from chickens and chickens are animals. To me, the powder is just a supplement and I wasn’t even thinking what it was made of. However, I will now have to give it up since it will interfere with my Vegan diet. Here is the question (as stupid as it may be): would this type of calcium REALLY mess up my Vegan diet? Perhaps I am desperate to be advised not to stop my eggshells powder as it is so convenient to make and to consume…Any advice, people?

    • if you check out the ‘how to heal your teeth naturally diets’, they all recommend eating eggs as well as meats, along with high quantities of vegetables low amounts of fruits zero nuts and zero beans because of the phytic acid. And LOTS of calcium. Healthy teeth = healthy body. When I was vegan, I felt very unhealthy. IMHO, be vegetarian. Eat eggs, consume lots of calcium.

      • Re nuts and teeth. When I was eating tons of almonds, the dentist remarked on how strong my teeth were! Almonds are high in calcium as well as magnesium.

        Echoing Amber’s post, I too would like to know the shelf life of ground eggshells. I found a container of them in the fridge that I had forgotten about. They look and smell fine but I’m not sure about consuming them…

    • To achieve the important goal of functioning optimally follow a nutritional program, not a food program. We are omnivores. We need some properly prepared animal products.

    • To get all the macro minerals I eat 1/4 of an organic banana peel 4 times a day. Google benefits of eating organic fruit peels. I also soak organic citrus peels in water and then drink the water. Most of the nutrients are in the peel.

  14. Hi Genevieve,

    I followed your recipe for the eggshell calcium, & ground it in my coffee grinder but the finished product seems grainy … is that normal …is it suppose to disolve in water completely … mine seems to leave some of it on the bottom of the cup i am drinking from … will putting in hot liquid destroy the calcium benefits? Thanks

    • The best way to assimilate the egg shells is to dissolve them in a good quality vinegar like Braggs. They are easier for body to absorb, and the vinegar is nourishing as well.

      • Good idea. Thanks.

    • I just saw an Ncestry T.V. program with a man tracking down a great great grandfather. Upon finding family who knew him, told of him living to 114 yrs old.
      Older gg grandfather consumed finely crushed eggshells (rollerpin) everyday by swallowing them in a half cup of good-ole Milk. (Almond milk for me) Flax milk would work too, to balance out with right proportions of Magnesium! o/

      • Oh, have to put shells in a freezer bag to crush with a rolling pin. Per Ancestry relative t.v. program secret of long longevety

  15. …if you want the benefit of the Hyluronic acid that is in the membrane, peel it out before cooking the shells-heat destroys Hyluronic Acid

    • Do you have any suggestions on how to ingest the membrane? (amount, frequency, etc)

  16. Our organic chemistry lecturer at university was very clear about the uselessness of taking calcium supplements in the form of calcium carbonate: “You might as well eat chalk. Your body can’t digest it.” He also added that if instead you took calcium in a chelated form, then this provided the necessary “molecular hooks” for the body to absorb the calcium and use it. It’s like getting calcium from food, as opposed to eating limestone. E.g. see http://www.greenmedinfo.com/blog/turned-stone-calcium-pills-proven-once-again-kill?page=2

    That said, there may be some benefit from the eggshells – perhaps the 3-5% of the shell that’s made from proteins provide something useful. Though I wonder whether it might not be better to grind it up, since boiling it might break up the proteins.
    Or perhaps even the eggshell membrane: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2697588/

    • If there’s no use in eating eggshells, why do my chickens eat them up like they are a yummy treat? They must be absorbing the calcium somehow. When I keep the eggshells and don’t feed them back to them, the eggshells of the newly laid eggs become noticeably thinner. They also eat ground up oyster shells. Would there be a reason chickens could absorb it more easily than people?

    • Your chemistry teacher is wrong, unfortunately. I am a former organic chemist and currently a med student. There are literally hundreds of studies that prove calcium carbonate raises serum calcium levels. As soon as calcium carbonate hits the acid in your stomach, it dissolves in the stomach acid. The calcium and carbonate ions separate and the carbonate reacts with the hydrochloric acid to form carbon dioxide and water. This frees up the calcium ion to be absorbed in the gut. And in fact, studies have proven that amino acid chelated calcium is LESS absorbed than calcium carbonate because the calcium is less likely to separate from the amino acid and the transporter for calcium is designed to absorb the free ion, not calcium chelated to an amino acid. You can look it up. Many minerals have improved bioavailability when taken as chelates and not inorganic compounds, however calcium is not one of them.

      • I have begun to simply crunch my way through the eggshells, along with the egg yoke and white of course, after boiling my breakfast egg. Do you believe that is enough because of the acid in the stomach you refer to for the eggshells to be absorbed? I look forward to your reply.

      • Could you please simplify your response for the layman, such as myself? What would you recommend as the best way to consume this?

        • Consume about 1/4 tsp 3 times a day. Don’t take more than 1 tsp a day.

  17. Hi! I would like to try this with my 3 1/2 years old boy (he have already 2 cavities and I think it would help to slow down or even stop the process) and my 1 1 /2 year old baby… Do you think it’s gonna be ok for them? And how much I give them?
    And by the way, thank you for sharing!

    • I’m not sure about calcium helping with cavities. But I do know of people healing cavities brushing with Young Living Thieves oil or Thieves toothpaste. I have also seen various articles online, some of which include bentonite clay.

    • Check out ‘how to heal your teeth naturally’. You can find it free on the app Scribd. It is a diet mainly consisting of eating a lot of grass fed meat a lot of grass fed Dairy, zero sugar zero nuts zero beans because of the phytic acid and lots of vegetables and lots of calcium. Brushing with coconut oil. Consuming gelatin and eggshells to strengthen teeth. Good luck!

    • To strengthen the teeth, and, even build up the enamel use coconut oil as a mouth wash.
      Couple of table spoons a day great to make sure not parasite, even Canndita, problems, awesome brain food, just a few of the benefits of this wonder food.
      Mix it with unpasteurized honey for a great spread, wonderful on pancakes, baking, etc.
      DME brand is one of, if not the best.
      Check out the YouTube vids on how it is processed.
      No, I am not connected with the company in any way.

      https://www.youtube.com/watch?v=64VU0ngEXEI

      For the shells, just bake them at 250 degrees for 20-30 min. then you don’t have to boil and dry.

      Cheers

  18. thank you so very much about your information cocerning eggs shel

    • The study does not specify which calcium supplements the participants took, so I’m thinking they are probably from a non-natural source. There is a difference between synthetic and natural supplements, and although the author from the website citing the study, Sayer Ji, Founder, criticizes the natural ones (e.g egg shells), I couldn’t find it anywhere in the study reference to eggshells or another form of natural calcium supplements in specific. Just sharing my thoughts on this :)

      • My understanding is that calcium in most forms, including eggshells, will contribute to adverse health consequences unless consumed with adequate vitamin D *and* K2.

  19. Hi

    I’m 9 weeks pregnant, and I would really like to try this, but I’m concerned if it would be harmful to my developing baby. We are told not to eat a lot of things during pregnancy due to bacteria etc, so my question is, does boiling destroy any possible bacteria in the eggshell that could harm my baby?

    • The thing that will hurt your baby most is malnutrition.

  20. Can you just hard boil the eggs and then peel them, let them dry overnight? Oh and put them in oven for 10 minutes at 200 degrees, that would work too right?

    • Yep! I’ve done it that way. Dries them out so well that I didn’t even need a coffee grinder. Just a food processor. Actually, boiling the shells and draining them, like they mention here, would result in literally pouring calcium down the drain.

  21. My family thinks I’m crazy for eating eggshells! But to me it feels like the most trustworthy way of getting my calcium without any undesirable extras like the hormones in dairy or the phytic acid of my almond milk (phytic acid = blocks mineral absorption). So the eggshells make me very happy. Sometimes I overdose and it backs me up (bathroom-wise), but I like to take it along with a magnesium supplement to assist with absorption.
    I buy a carton of organic eggs, and whenever I’m cooking eggs (I use about 4 at a time) I rinse out the emptied shells and boil them for a while — until the pink stamp on the shell disappears, if there is one — and then I place them on a sheet of paper towel to dry out for a day. When I’m ready I crush them up with a marble rolling pin! The shell & dried membrane particles are stored in a little container and keep for months as long as there is no moisture.
    :)

    • Hi!
      This is the first time I hear about egg crushing for calcium.
      in all honesty, does it really work? How often do you check your calcium level to confirm it’s working?

  22. I’ve had to give up dairy due to a sensitivity to milk butyrophilin so looking for ways to make sure I get enough calsium. I tried this method but by mistake I put the egg shells in a 200 degees C oven! not F. So double the temp. They came out a bit burnt at the edges. Do you think I could still use the shells if I remove the burnt bits?

  23. I just wanted to let you know that the two studies you cite are really the same study listed twice in Pubmed.

    I have a question. Egg shells will dissolve in vinegar. Has anyone studied the bioavailability of calcium in liquid form? Vinegar is consumed by many people. Dr. Jarvis recommended it with honey years ago. The debate in calcium supplements is whether the calcium is available to to the body and useabe bologically. It would seem intuitive that the nutrients in an egg shell would be more easily digested in liquid form and the vinegar and honey would probably settle a sensitive stomach. Anyone have thoughts on this?

    • Yes, when I take eggshells as is, I notice a lot of it just comes out the other end… But that’s not the case when I take eggshells along with magnesium. Back when I was reading around the web about using eggshells to combat cavities and restore tooth structure, someone commented that they did not notice a visible change in their cavities until they added the magnesium. Then the cavities disappeared over several weeks! I myself don’t have noticeable tooth damage in the first place but I do notice a real improvement in the enamel of my teeth and nails when I take magnesium + eggshells.
      I’ve read that calcium is best absorbed and used by the body when combined with Vitamin D (sunshine in the summer, supplement during the winter), Magnesium, and even some Vitamin C.
      By the way, calcium is more easily expelled from the body than it is absorbed. Animal protein and salt make you lose calcium (when you pee) faster than you can build it back up again. Hence the plague of osteoporosis in our burger & fries loving society, despite our equal love of dairy!

    • like most supplements, vitamins you should space them out about 2 hours apart the body will absorb what it needs also prevents reactions to meds and supplements.

    • Dr Christopher recommends getting calcium this way- through dissolving eggshells in vinegar. It certainly would make the calcium more bioavailable.

  24. Hello! I wonder if the hit destroyed the calcium?
    We can wash the eggshell, dry overnight, pulverized and then eat.

    • i would heat in oven to kill any unwanted bacteria.

  25. I would just like to throw some science into this discussion. Eggshell, due to it mostly being calcium carbonate, will make acids more neutral. This process releases Calcium into a form that is digestible. Your natural stomach acid should work in your favor in this respect. Just plain shell dust will be absorbed, as long as your intestines can keep up. Due to this process requiring acidity, there should not be a significant amount of calcium in water left over from boiling. That is not to say there is none. Just not much. To produce a rapidly available source of calcium, dissolve them in vinegar until the bubbles stop. This should be used sparingly because it makes the calcium easier to be washed away from targeted plant roots.
    Microwaving eggshells will not decrease the calcium content. Calcium is a mineral and microwaves only degrade vitamins.
    Boiling shells should remove anything like chicken poop and kill germs. Microwaving might do the same, I don’t know, but I would go for boiling or baking for 15 mins at least at 180° F if they are to be eaten.
    I hope this helps with some of the points brought up that chemistry and biology can provide answers to.

    • This might sound silly after all of this talk: I have merely been putting my shells aside in a ziplock thinking I’d get to this in a few days. Well, it has been a month thanks to having our first little one. Still safe to use since it will still be put in the oven?

  26. I was looking around a few different sites to compare techniques and they vary.
    One site says to bake at 300 degrees for 20-25 minutes,
    another site says to bake at 300 degrees for no more than 5-7 minutes,
    another site says to boil them for 5 minutes,
    another site says to boil for 10 minutes then let dry then the next day bake at 200 for 10 minutes…
    and finally, another site says to do nothing – just crack open the egg like normal, let it completely dry out for a couple days, then grind it up.

    What is your take on all of this? Do you feel its absolutely necessary (or not) to bake or boil the eggshells first? Is 20 minutes okay or is 5-7 minutes much better? Does it need to be boiled AND baked?

    • The boiling helps to get the membrane off the shell and kills any pathogens. The baking dries the eggshells so you can grind them. If you grind when still damp, you can get mold. I like my method but do what works for you!

      • The membrane should be kept on. I have read in several articles that it contains important nutrients for the joints which helps arthritis.

        I have used ground eggshell for years for my chickens, birds, dogs and cats.
        I’ve recently wondered about using it for myself, so decided to do some research. It’s all good!!

        • This might be true since eggshell membranes are now being sold as supplements in the regular pharmacies, and it says it’s for joint pain relief from arthritis. :) Peeling out the membranes is such a pain anyway, as long as it has time to dry out, it can be easily ground up with the rest of the shell.

      • The billing for 10 minutes is the same as my disinfecting routine with my breast pump gear. But I’ll also use the stream bags which are much easier. Could I just put my eggs in the Medela stream bag and disinfect that way?

        • *Boiling*

  27. Is it absolutely necessary to cook the egg shells first?

    • Depends on what your going to use it for I think. I have washed and dried them rely well and used for my dogs, cats, chickens and birds!

  28. “and try to get eggs from chickens that don’t eat soy”? why?

    • please explain to me why the chickens shoudn’t eat soy. is it because of estrogens? i just find out that the eggs i buy are from the chickens which eat 5% of soy.
      thank you :)

      • Chickens are not supposed to eat soy. Have you ever seen a chicken fly up to the top of a bean or grain plant to eat? They peck at the ground. What do you think they will find on the ground? Bugs, worms, seeds, etc. That’s what they are supposed to eat. All those egg cartons at the grocery store boasting how the chickens that laid them ate an “all vegetarian diet” as if thats a good thing, is all marketing spin.

        • And just to add to your great response: soy is the number one genetically modified food in the world. Next is corn… It’s important for people to know this and always feed organic to their family (animals included here of course!)

        • True, but chickens WILL eat beans, soybeans, etc that have fallen from their shells. I don’t see soy being such an issue. Next we’ll be screaming “But they’re eating wheat!!!”

          • Haha, I have 40 free ranging chickens and I was shaking my head until I read the comment about “But they’re eating wheat!”. They love bugs but they will eat absolutely anything they find, especially if they get in the garden. My beans are usually safe just because they are beyond their sight. But beans on the ground are fair game. They also like grains. The wild grasses that grow in our yard are some of their favorite things to eat. Being that the seed heads are at chicken head height, they go to town on those.

            Like children, if they are given a selection of healthful options, chickens eat what they need. Again like children, they will also eat junk too.

            I would ignore the organic label and definitely the “all vegetarian feed” label. Look for pastured eggs with some kind of humane certification or look on craigslist for someone in your neighborhood selling eggs where you can go see the chickens for yourself. Even better, check your city ordinances and then get a few hens for your backyard. They are almost as easy as a raising a bowl of goldfish (sturdier even).

      • Is refrigeration necessary for the eggshell vinegar? How long can I store it?
        It taste a bit bitter, is it normal? The smell is weird!

    • Ninety percent of all soy products are Genetically Modified. Your best bet is to get eggs from chickens being fed all organic feed.

  29. Great idea for calcium and I know boiling the eggs is a very important step but doesn’t this cause calcium to leach out of the shells and into the water? If so, wouldn’t you be better off saving the water and drinking a tablespoon or so at a time of this instead?

    • I’ve been making eggshell calcium for awhile now. I keep the shells in the freezer until I have a dozen or so shells. Then I cook them in the microwave for 2 to 3 minutes without water, which preserves the calcium, kills pathogens and dries them out at the same time. Okay, I know it’s not natural to use a microwave, but it works well for this purpose. I buy empty capsules at our natural food store and fill them with the ground calcium. I take three capsules a day, which is just under 1 teaspoon.

      Another tip: Wash your eggs before you open the shells. It’s much easier than rinsing broken shells.

      • you should really read up about microwaves and their harmful effects on the nutrients

        • Microwaving has a negative effect on vitamins, NOT minerals. Calcium is a mineral and microwaving the shells will not effect that at all!

        • In order to destroy calcium (a nuclear reaction) you’d need a large particle accelerator. Microwaving it doesn’t hurt.

    • Does anyone know how much calcium is leached into the water when boiling? Would like to drink the calcium-enriched water, but want to know how much calcium it contains.
      Also, will adding vinegar help with the leaching process?
      Thanks in advance for any links and info.

      • Just interesting article re: benefits of eggshell calcium vs milk and dairy from Natural News.com.
        This site deletes posts with links for certain sites, hence re-posting without the link.
        Just go to Natural News and type in calcium from egg shells in search area on right top corner.

        Not sure why “for two months each year”. Wonder why not everyday?

        Copy and paste:
        take a 1/2 teaspoon a day, which can be taken with fresh squeezed orange juice or lemonade. For prevention, the shells are consumed every day for two months each year.

        • Correction on typo — Meant “just found interesting article…..”

      • Did research and found this:

        One whole medium sized eggshell makes about one teaspoon of powder, which yields about 750 – 800 mgs of elemental* calcium plus other microelements, i.e. magnesium, boron, copper, iron, manganese, molybdenum, sulphur, silicon, zinc, etc. There are 27 elements in total. The composition of an eggshell is very similar to that of our bones and teeth.

        *Elemental amounts are the amounts absorbable.

        From: nourishedmagazine.com.au/blog/articles/how-to-make-calcium-using-egg-shells

        But also found very interesting article that for age-related bone loss, Vit C, D3, K2, boron, silica & weight bearing exercises are more important than supplemental calcium. Too much calcium clogs arteries.

        naturalnews.com/046168_age-related_bone_loss_supplemental_calcium_nutrition.html

      • Search egg shells in Google. There are heaps of articles, sites and blogs on this topic. You will find your answers this way

  30. I use egg shells to brew my water kefir since the yeast/bacteria culture feed on minerals. I have assumed that I am adding calcium to my diet as I drink the the water kefir. Does anyone have any more info on this?

  31. hello

    when you make homemade egg shells for calcium, how many days it will be using with fresh?
    is there any time for or can I use till my eggshells end?

    and how I can keep that egg sheel in fridge or tempurature room is enough to store?

    thank you for answers have a healthy days.

  32. How much should I give a 3 and 5 year old?

  33. So when I’m trying to get calcium out of eggshells for my garden I break down the egg shells (which are calcium carbonate I believe) in 2 to 1 water to vinegar which separates it into calcium and hydrogen. My question is, is the calcium what is left over in the egg shell or is it in the water.

    • Hello there! I believe it’s in the water. When making bone broth you typically add cider vinegar and let sit for an hour to ‘leach’ the calcium and nutrients out of the bones and into your yummy broth! I would suspect the same with egg shells. So, skip on the vinegar treatment, unless you want to drink the water or use it in a soup ( but I haven’t tried this).

    • the liquid left behind from dissolving eggshells in vinegar is where the calcium is. The acid in the vinegar breaks the calcium carbonate (what eggshells are) into pure calcium and carbonate ( CO3 gas) which is what causes the mixture of eggshells and vinegar to bubble. Normally what I do when my aquaponics system is low on calcium is filter the vinegar and egg mixture through a coffee filter after the bubbling stops then pour the liquid into the tank. The reaction also neutralizes the acidity of the vinegar so it shouldn’t effect your ph either.

  34. I need help!!

    I have been grinding up my last few cartons eggs since reading this and I’m super into the idea! But.. I feel like the powder is way too “crunchy”.

    I jumped over to this site from a link on another site talking about making toothpaste. A reader suggested making your own eggshell calcium for the recipe rather than buying her suggested calcium magnesium powder.

    So, I originally made it for my recipe. I feel like it is DESTROYING my teeth! I get chunks of eggshells when I’m brushing my teeth so I brush really lightly but still.. I have also been trying to take it in the morning by mixing in a glass of water, and I get all these eggshells stuck in my throat.

    Should I give up the toothpaste dream or is it possible to make it more powdery? I am using a coffee grinder but I also have a Ninja food processor.

    • I have a capsule machine and I buy veggie caps to make my own natural supplements. Neither one are very expensive. I think you can get them from Amazon. I also have chickens so I will make up capsules with ground egg shells for myself. I usually give group shells to my chickens but now I’m going to try them.

      • You clearly only read the first paragraph because this person was asking about using it in toothpaste and NOT about taking it themselves. So your comment about capsules doesn’t apply here.

    • I have vitamix dry container and it blends mine into the finest, softest powder! You just need a better grinder.

    • I put the ground eggshells in vegetable capsules from a natural foods store. You can get a machine to fill the capsules, but I use a tiny funnel from a beauty supply store. Works great!

    • I used to use a coffee grinder to make calcium for my dogs & it was crunchy too. But with the NutriBullet, I can grind it into a powder. If your Ninja has a separate blade for grinding nuts, etc., use that.

  35. For additional calcium I usually drink milk, eat eggs and seafood such as crab, fish ..
    I was wondering what your homemade safe or not?

    • why would you assume you get calcium from milk? please stop believing what your told, the body cannot assimilate calcium or any other nutrient (apart from sugar and water) from milk due to the pasteurising process. also eggs cause sulphuric acid so if your ill its not a good idea to consume eggs or milk although the calcium you get from the eggshell is ok. to truly protect your bones and teeth you need to take Boron, Boric acid is its natural form on this planet and is essentially sunlight believe it or not, you need 3 mg a day of Boron Boric acid is 17.5% and Borax is 10% of Boron you also need to combine with 4-600 mg of magnesium a day.

      • The specialist has spoken!

      • You are not seriously suggesting that heating milk to around 160 degrees for 15 seconds degrades calcium in such a way that it is not accessible by the body.

        You’re seriously saying that.

        • Saponification in the stomach is the reason adults don’t absorb Ca+

      • Pasteurization is The heating of milk to a temperature of at least 161°F to kill the bacteria in the milk. If this process makes the calcium of the milk un-absorbable by the human body, then how is it that we can absorb the calcium of the egg shells which have been raised to the temperature of 212°F when they were boiled? I’m not trying to be difficult or antagonistic, but rather I truly want to understand The science behind it all. It Currently does not make sense to me!

      • Doesn’t all boric acid contain arsenic?

      • Kind sir, perhaps this person drinks raw milk, which is in fact an excellent source of calcium, among other things. Why do you assume they meant pasteurized milk?

      • A recent New York Times article reported a large study in Scandinavia found that women who drank at least 3 glasses of milk a day not only did not improve bone density but were dying at a much higher rate than other members of the study who ate/drank dairy in fermented forms such as cheese, yogurt, kefir, etc. Women who ate/drank fermented dairy did improve their bone density. So it appears that drinking milk (and I assume this is pasteurized milk, although I don’t know for sure) is dangerous. Too bad for me. I love milk and cannot eat cheese because of high cholesterol. Looks like unfermented milk is junk food.

        • I had extremely high triglycerides of and low hdl. i went on a diet of no flour or sugar and low carbs, using loads of eggs and cheese and yoghurt or kefir. in 2 months my triglycerides lowered to 80 from 295 and my hdl went up. So look up the cholesterol myth online. I also drank raw milk. I stay on this diet for life. Literally! I’m going to try adding a soft boiled egg to my morning green drink. shell and all, because of this post. Stay away from statins!!!!

          • Amen to all Gina has said.

      • dave recommended TOO much Magnesium in a day. Most if not all people cannot assimilate effectively that much Magnesium. I’d add Mag every other day and use the Magnesium oil that is out now and rub it onto your skin.
        I have also gotten used to the ground up but crunchy eggshells. After cleaning the whole egg(s) in a water vinegar mixture, I rinse them off and put them in a blender with a slight amount of lemon or orange juice. Grind them to a paste if possible but my blender cannot get the grains that fine. I mix the ‘mix’ in with about 3-4 eggs in the blender then scramble them. A little salt and pepper and salsa makes them taste good enough. I cannot take this amount of calcium daily..my system cant accommodate it but 2-3 times a week I do and I feel amazingly strong and at ‘peace’ all day. The chewing of the shell powder helps to assimilate the calcium from the start and it is in a better form when it gets to the stomach etc for use. I’ve done this for a year and think its as important to my well-being as using the Iodine Protocol. If you have no idea what the Iodine Protocol is, research it, you’ll be amazed what you don’t know how important Iodine is to your life….the RDA for Iodine is a drop in the bucket from what you actually need to thrive

      • I only drink raw milk. plenty of calcium there.

      • Why do you have to boil them? I baked them in a nice hot oven then ground them. Seems to be working fine

      • I love how you say “stop believing what your told”, and then proceed to tell us something. And why would you ASSume they are drinking pasteurized milk?

  36. If your going to boil the eggs, don’t throw out the water when your done. Let the water cool then add it to your garden. Tomatoes and other nightshade plants love the extra calcium. One way to prevent “end blossom rot” in tomatoes is by adding calcium. You can also top dress with the powder, or make a calcium tea that you can water your plants with. It will also raise the PH balance of your soil.

    Some people say that the powder will keep slugs away, it’s like glass to them and will shred their undersides.

  37. *grabs popcorn and sits back to read the comments*

    • I’ve used calcium carbonate in the past. (dolomite powder) I tried to use it in my coffee maker with the grounds and it clogged up the paper filter…i did this to try to alkalize my coffee a bit(now I use baking soda) i’m not sure we have the same digestive systems as chickens(see other posts) to break down the shells…so I think maybe i’m going to boil my shells, cool the water and make ice cubes out of it to add to soups,.stews and home made ice tea…that is, if I do this at all…there is a raging debate over whether we should be taking calcium at all. Remember, cows get their calcium from eating grass! Kale,.bok Choy etc. contain calcium.

      • Me again… Also: some studies show that without Vitamin k,.calcium will “calcify” our arteries,.heart, kidneys, gallbladders instead of our bones…. Which is a sign of aging….

        • Absolutely true. I just been diagnosed with osteoporosis. I m at the heart of thorough research for strengthening my bone and … especially my gums. K2-m7 n vit D are largely discussed and used by naturopaths n their clients. After all…what’s the use in taking it if doesn’t end up at the right place.

          It apoears that now calcium is to magnesium what k2-m7 is to D3…all this lil mix…according to the experts, allows for the calcium to b removed from where it could create problems-in the tissues, and move it in the bones and teeth. I just restarted taking eggshells. I will experiment with the recipe here! It’s rough on the stomach to take it like I was. Each time, after ingesting it, i would end up feeliing tired, not too good, and was getting really painful headache. I was not cleaning the shells but simply grinding them and rinse my mouth with the piwder n water . Drink some of it… brother…bad idea…

          Tonight i ordered these cocofed eggs. We’ll see how that goes.

          Thank you for all your posts it really helped me. It provided me with so more info! Hey…thanks guys. Louise

          • Sorry for the long post. 8 (

          • My mom had osteopenia and search for years to find a way to absorb calcium. The doctors would test her urine and find that 100% of the calcium she was taking as supplements (along with magnesium and vitamin D) were being eliminated from her body. She was absorbing 0%! She also did impact exercise and everything else they recommended, stopped eating refined sugar and absolutely no caffeine (ie chocolate). Nothing helped. She finally went to a naturopath and found out that she was allergic to corn, soy, wheat, shellfish, and dairy. Her digestive tract was so inflamed that she was malnourished no matter how much she ate. Once she started eating a diet that eliminated those foods, she became much healthier.

            Sometimes the solution is not so easy as people make it out to be. And everyone’s body is unique. So I think that it is why it is so important to listen to your body and pay attention to what it’s telling you.

      • Thanks for bringing this up. Some folks recommend avoiding calcium carbonate to help to decalcify the pineal gland. Thoughts?

      • Cows get calcium from grass, but we don’t have four stomachs so I doubt humans can derive much calcium from greens. Don’t forget the importance of K-2. This is a vitamin that is found in the milk of mammals but not in bloodstreams of the same pregnant women who make K-2 in their breasts. Humans have to get K-2 from Gouda cheese, pastured egg yolks, dark meat poultry, Natto, cottage cheese, other fermented cheeses, etc.

        • Um cows don’t have 4 stomachs it’s 1 stomach compartmentalized that’s why they are ruminant animals.

          • 1 stomach 4 compartments so to speak.

    • i know!

  38. I blend eggshells, washed and disinfected with hydrogen peroxide on the nutribullet 900, they are powder in a blink.

  39. calcium, magnesium and zink all work together, is there a natural way to get zink like you are with the calcium?
    You need to moderate and delete some of the bad/mean and off topic comments

    • zinc cancels out magnesium never take these together, always wait 3 hours between eating so your body can use up the nutrients for where it needs them

      • how about we just eat healthy food and not worry about all this supplementation insanity.

        • Do you realize you would have to eat 50 oranges to equal the nutrition value of an orange our parents ate 50 yrs ago? Our soil is so depleted of nutrients which is why we need supplements.

        • Shawn, since our food grown by large farms has depleted the top soil, we don’t get all the nutrients that should be in our food so we, unfortunately, need supplements.

      • Zinc and calcium also compete for absorption.

        The study has shown that, during zinc supplementation, the intestinal absorption of calcium was significantly lower during a low calcium intake than in the control study, 39.3% vs 61% respectively, p less than 0.001. However, during a normal calcium intake of 800 mg/day, the high zinc intake had no significant effect on the intestinal absorption of calcium. These studies have shown that the high zinc intake decreased the intestinal absorption of calcium during a low calcium intake but not during a normal calcium intake.

        http://www.ncbi.nlm.nih.gov/pubmed/3584729

    • Lots of zinc in oysters. Also in beef, lamb, sesame seeds, pumpkin seeds, lentils. Do computer search of “zinc rich foods” for a full list.

    • yes, I generally add a 50mg tab of zinc gluconate (sometimes 100mg) to my eggshell mixture…..the calcium buffers the high acidity of the zinc and the two seem to assimilate WELL together for me. I workout in the gym later that day like a madman….the calcium really seems to be good for me but as I stated before, I cannot eat calcium eggshells more than 2-3 times a week……too much and it stresses my kidneys and I get ‘night shakes’.

  40. I think it may be better to steam the egg shells instead of boiling if you want to kill pathogens without leaching out the calcium and minerals.

  41. Again, do your research:)
    It’s not calcium carbonate. So funny how ignorance can get ya every time.
    Agree with the hate comment. People that lash out at others in that way are generally just unhappy with themselves.

  42. All that hate, wonder how healthy it is.

  43. Hi Genevieve Im so happy reading this! Ive been doing the same for years. I always feel like a bit of a weirdo whenever I tell anyone about it, every though, when ever I do, people always find it interesting.

    Im a gardener – grow my own veggies – and an avid composter – extreme home composting 😀 But egg shells take forever in the compost bin and Im mean, jeez, why wait?! If you pulverize in now, your garden can be gobbling up the calcium+ today! Also its really good for the worms in my worm-composter – scours their gut.

    Anyway, one question … I understand the need to kill potential pathogen but is the boiling really necessay? Why not just bake? How long how hot would be safe, do you think? Just trying to streamline the process here — we eat a LOT of eggs!
    Anyway, thanks for writing this :)

    • You probably could just bake if you get your eggs from a pure source. Boiling also helps to separate white film. Totally up to you :)

      • Hi Genevieve

        If the eggshell I use are from hardboiled eggs I think I could skip the safety steps if I peel them soon after boiling. Do you agree?

        • That makes complete sense to me Marcus! And like other comments mentioned above, you can save the boiled water from hard boiling your eggs and when it cools down to room temperature pour it on your garden (tomatoes, etc) to give them the calcium that is in the water. :)

          • Does anyone know how much calcium (per egg shell) is leached into the water when boiling? Prefer to drink the calcium-fortified water rather than consume the egg shells, but would like to know how much calcium can be obtained from the water used for boiling the shells or eggs.
            Thank you so much in advance for your help.

    • Monika-have you done your research, she is not advocating the grinding and injection of stone. She has resources listed so that you may be more informed.

    • Some calcium you can get in the store are from oyster shells. I would think they are harder to digest than egg shells. Am I thinking right?

      • Used to take calcium supplements made from oyster shells, but still developed osteopenia.
        A study I read many years ago suggested dropping a calcium supplement in carbonated water to see how fast it dissolves to determine its effectiveness. The calcium tablets made from oyster shells passed the test , but it is probably not a very accurate test as it does not measure how much the body actually absorbs the calcium.

        Try to get most (not all) of my calcium from food — almond milk (higher calcium than milk, although not sure how much of it is from the almond and how much is from added calcium carbonate), sardines, string cheese (not as fatty as other cheeses), beans, sesame seeds, sunflower seeds, home-made orange juice, etc.

        Have switched to calcium supplements made from Icelandic Red Marine Algae (which also include Magnesium, Vitamin D3 and Natural K2 Complex) and doing exercises to increase muscle and bone density. Will know if the supplement and exercises work when I get bone density test again next year.

        Also important to remember that the body can absorb only 500 mg of calcium at a time. Need to space calcium intake by at least 2 hours (max 500 mg each) throughout the day. Please also keep in mind that it is best to take zinc separately, although studies say high intake of calcium is not affected by zinc.

        http://www.ncbi.nlm.nih.gov/pubmed/3584729

        This is the calcium supplement I currently take, but hope to replace it with calcium-fortified water from boiling eggs or egg shells when I get more definitive answers on how much calcium is leached into the water (any info would be greatly appreciated…thanks in advance):

        http://www.newchapter.com/take-care/bone-strength-take-care

        Genevieve, thank you so much for posting this article.

    • Read up on Vitamin K-2. It keeps calcium were it should be, in teeth and bones, and out of heart, arteries, and other tissues. Japanese eat tons of it in Natto. The dutch have high levels of K-2 from gouda cheese and pastured egg yolks. Some say Japanese people have smoother skin into old age from high K-2 levels.

  44. Hi – very interested to read of using eggshells this way – went to copy the url into my browser and it automatically added other stuff added at the end of the url, which led to a ‘no page at this address’ result.

    Only when I shortened it to just http://www.ncbi.nlm.nih.gov/pubmed/15018022 did it take me there.

  45. Hello! Great info here. I have chickens and I think there is soy in the laying pellets that I gave them last week but this week I bought them scratch. Have to check to see if it contains soy. So what if they have had soy in the past, are the egg shells still not beneficial to eat?? If I wait a couple of days/weeks after them being on a non soy product, will this insure that soy is not in their eggs?? Please help answer this because I just found out I am pregnant and I really want to start eating my egg shells for the calcium and now I am not so sure because of the soy in their food….Please help!
    thanks
    Rebekah

    • Keep looking for some non-GMO chicken feed. Scratch, I hear, does not contain all the nutrients chickens need. It’s like fries and potato chips to us — a nice snack and a little something on winter afternoons to help them stay warm at night. I was lucky enough to find non-GMO layer feed from a local farm on Craig’s list — only half the price of non-GMO feed at the feed store, which has Cargill labels. (You want to stay away from supporting Cargill if you can.)

  46. if we do not wish to digest it, can it be used in a lotion, salve, scrub? thanks for the ideas

  47. I missed the step of boiling the eggshells.Oops. I put the eggshells in my food processor and ground them up. Didn’t make powder but very tiny pieces. I put 2 tablespoons in my shake every morning.
    Do you think I’ll still get the same benefit from doing it this way.
    Thanks for all your helpful info!!

    • could have bad bacteria from not boiling. boil next time :)

  48. Mike you don’t have to believe. Go take a hike. If you are a rocket scientist, you are a pretty stupid one. The rest of us will be happy to try it. You probably make your living selling expensive, ineffective OTC supplements.

  49. DOH ! I do this for our birds, I don’t know why I didn’t think to do it for us.

  50. Ummm I think they mean pasture as in the opposite of caged….I.E. free range. Free range chickens are raised in a pasture- which is a pen that is made up of fencing used for farm purposes so that the chickens while still contained, have plenty of room to roam and live normally vs. being cooped up in cages in substandard miserable living conditions.

  51. start your research here:

    Eggshell calcium in the prevention and treatment of osteoporosis.
    Rovenský J, Stancíková M, Masaryk P, Svík K, Istok R.
    Source

    National Institute of Rheumatic Diseases, Piestany, Slovak Republic. rovensky@nurch.sk
    Abstract

    In this paper the most significant biological and clinical aspects of a biopreparation made of chicken eggshells are reviewed. Eggshell powder is a natural source of calcium and other elements (e.g. strontium and fluorine) which may have a positive effect on bone metabolism. Experimental and clinical studies performed to date have shown a number of positive properties of eggshell powder, such as antirachitic effects in rats and humans. A positive effect was observed on bone density in animal models of postmenopausal osteoporosis in ovariectomized female rats. In vitro eggshell powder stimulates chondrocyte differentiation and cartilage growth. Clinical studies in postmenopausal women and women with senile osteoporosis showed that eggshell powder reduces pain and osteoresorption and increases mobility and bone density or arrests its loss. The bioavailability of calcium from this source, as tested in piglets, was similar or better than that of food grade purified calcium carbonate. Clinical and experimental studies showed that eggshell powder has positive effects on bone and cartilage and that it is suitable in the prevention and treatment of osteoporosis.

    • Thank you for this….I love details!! :)

  52. I had pet birds and it was suggested by books to feed them my leftover eggshells for calcium. I give my houseplants the water from the boiled eggs. The birds loved it.

  53. Hello all, thank you all for shearing, thoughts,wisdom,knowledge. This article and comments has touched me deeply. Normally I do not comment in open fourms like this but I would like to give this a try. The memories of growing up with nature, growing vegatable, fruits, expanding horticulture, boy scouts, ect ect. Become better to understand there is a true natural balance in everything we touch, smell, taste, see, hear. It takes networking with others like this to repourpose egg sheels that becomes full circle renewable resouroes that comes back to us 100 x over. Like using ground oyster shells for pourtry scratch in egg production, and in Koi ponds to balance slow release calicum to reduce acid levels. Ill will stop before i ramble on. Thank you John

  54. Tara
    I’m not sure why you feel that article “balances” this one. It says that it’s best to use natural forms of calcium and to make sure you are getting enough of the other vitamins and minerals that are needed to work with calcium in the body.

  55. Your remarks on magnesium are so true. My husband has a true magnesium deficiency. I say true as it is not brought on by alcoholism or drinking at all. He had a severe physical problem about six years ago which the doctors could not figure out. He had been on the floor vomiting and his eyes were rolling around in his head. I called the ambulance. They arrived and took him to hospital. They thought he had a stroke. Then they thought heart attack. Sent him to a different hospital in a nearby city. They sent him to the neuro floor. Again no one could figure out why his eyes ere rolling around in his head. Had him hooked up to ekg machine. It showed extreme arrhythmia. They checked his magnesium levels after all other mineral and vitamin levels were checked. Said there was NO magnesium left in his system. Put him on a drip for two days. It took that long to get it to normal range. In the two days in the hospital he was hallucinating, talking to people who were not there, made no sense in phone calls and kept having the arrhythmias, even tho’ he had no heart attack or any known heart problems. This just shows you what the lack of magnesium can do to the body. It works with the muscles to keep them running smoothly. The deficiency persist in my husband to this day, although now they have him on a two high blood pressure meds which keeps it from dropping really low. Oh and doctors get very little education on nutrition in medical school. That is the least part of their education. They don’t feel this is as important as the rest of their studies.

    • My leg cramps went away when I started taking magnesium supplements to help with calcium absorption. Just cannot take too many as it upsets my stomach. Doctor reminded me about “milk of magnesia”.

      So true about your comment re: doctors not being trained in or caring about good nutrition. Have several doctors in my family and all they care about are Rx medications — even for themselves. Keep reminding them to change their diets instead of relying on medications (lots of negative side-effects over the long term), but they think they know best. Thankfully, personally not on any kind of Rx medications. Truly believe in good nutrition and natural supplements.

  56. Calcium is also good for your skin. I use eggs in my soap to get proteins – remember egg facials? I am going to try to add the calcium from the shells and see how much I feel the difference. Great Idea! When I do it I will post the findings on Bubble Love Sedona Soap on FB – Thank you

  57. Great info! Just thought I’d add that you could also use this powder to sprinkle around tomato and clematis plants as both love calcium. I will also use it in the natural toothpaste you have posted.

  58. It’s a waste of time, energy, and filtered water to boil them before putting them in the oven. They will get pasteurized in the oven just fine :)

  59. I would think that boiling the eggshells will take out the calcium. Sort of like when some gardeners will cool the egg water from boiled eggs to water thier plant that need calcium.

  60. Is this calcium absorbable?

  61. Wondering….can I just add the powder to my tea and/or coffee in the morning?

    • You could try. It’s a little chalky though.

  62. Just a friendly note… All people and especially those suffering from kidney disease should know their calcium levels. Please don’t consume extra, since it can prove to be damaging for your body.

    • This is conventional medical thought and it is false. Just because our body secretes excess calcium does not mean it is taking in too much. The problem is a diet full of refined sugars and other processed foods that cause our body to draw out calcium in order to balance the acidity of the sugars. So we shouldn’t prevent people from getting calcium (that they are most likely deficient in) but to stop consuming diets high in refined sugars that suck the calcium and other essential nutrients out of our bodies!

    • People with kidney disease have to watch calcium consumption because their bodies cannot get rid of calcium through urine as they do not make urine any more. Some people even get a calcification of normal tissue and blood vessels because the calcium builds up. Dialysis does not rid the body of all excess minerals like the kidneys do.

  63. Bravo on the long post, but your “you’ve swallowed the Kool-aid” comment proves that you are either naive, young, or both. Do you personally know any doctors? Do you have any doctor friends…seriously?? Well, I do. One D.O. Who is very bent on natural living as a means of both preventing and treating illness. I know a M.D. who is both an ER doctor, as well as running his own holistic health clinic. I met him when I worked in mobile communications and he was specifically in search of equipment that was low EMF. Please stop generalizing human beings; we all, regardless of what we do for work, have interests- have you considered that physicians might possibly enjoy reading the same things you do? While I agree that many doctors may be inflexible regarding changing information, as well as there existing some who will sell out just for the extra money from pharma “sales”, many actually get into this line of work to help people…it’s actually true. The idea is to be knowledgable and be in charge of your own health; by you “not trusting” ANY doctors, you have yourself “drank the kool-aid”.
    You don’t trust doctors…until you need one. And everyone does at some point.
    My advice- stop the generalization and find some type of physician you trust at can back up your knowledge.

    I don’t oppose making your own egg-shell calcium, I simply stated that it would be wise to discuss sumplementation with someone who is both familiar with your personal health profile, as well as someone who knows well about how it could possibly interact with other supplements. You cannot possibly think its okay to get all of your health advice from blogs?!? (no offense mama natural!)

    • Agree completely. I had a friend that was a pharmacy tech and the best advice she ever gave me when it comes to self dosing supplements without knowing your true levels – potassium is what they use for euthanizing animals and for death row inmates. It stops the heart in large doses. Something we get from eating bananas. The point of this is that not knowing your own levels can be dangerous. Calcium and magnesium cancel each other out. So while calcium supplements can be good for some, magnesium is better for others. I am one of those that needs more magnesium, thanks to my coffee addiction that depletes magnesium lol. Keep in mind that balance is the goal, not overdosing on every mineral and nutrient known to man. Plants are the best example of this. Why we don’t use the same advice for our own bodies, I’ll never understand lol.

      • agree here. i’m a magnesium person but I only use it in small amounts on the days I don’t supplement with calcium…that way both have a chance to assimilate but I take days off from both too…my body needs both elements but my system can only stand so much so I’ve learned to separate them. zinc too is important for me

      • Thanks so much for info re: magnesium and calcium competing for absorption. From previous readings, thought magnesium was needed for calcium absorption. Only after reading your post did I do further research and found that in fact, they do compete for absorption! Really surprised and very upset as I was taking magnesium and calcium TOGETHER for the past few years! What a waste!
        Wish my doctor had warned me about it, but don’t think he knows.
        Calcium supplement I take also has magnesium (plus D3 & K2) in it.

        Copy and paste from article:

        Magnesium competes with calcium for absorption and can cause a calcium deficiency if calcium levels are already low.
        It is a good idea to take a B vitamin complex, or a multivitamin containing B vitamins, because the level of vitamin B6 in the body determines how much magnesium will be absorbed into the cells.
        Since magnesium is excreted by the kidneys, people with heart or kidney disease should not take magnesium supplements except under their doctor’s supervision.

        Very good article with dosage, drug interactions, magnesium from food, etc:

        Source: Magnesium | University of Maryland Medical Center http://umm.edu/health/medical/altmed/supplement/magnesium#ixzz3RncKr1Zj

  64. Thank you for the information. When I was a kid I watched my aunt crush up her eggshells and baked them for a few minutes in the oven. I asked why she did that. She said that she fed them back to the chickens she was raising to replenish some calcium that they need and it helped them produce better eggshells. It all made since to me then as well as now.

  65. Don’t be so ignorant, Sarah.

    • Dear Sarah, It isn’t that “all doctors” are ignorant to nutritional preventative health care. It’s that the the system is designed to weaken the individual’s well-being and too many cogs in the system (doctors, pharmacists, etc.) facilitate the profit guided system, at the cost of better living of their patients, in exchange for personal profit. These issues are never all or nothing, there is always grey area. The problem of ignorance/avoidance, among medical professionals and the pharmaceutical establishment, of the benefits of nutritional health care vs. invasive/dangerous procedures is real and it is very important for us to self educate because of this failing. We should discuss the issue with open minds. Attacking each other is a symptom of the problem. Best Regards, Julia

    • Wow. Mean!

  66. Thank you for taking the time to explain this process. I love homade wellness receipes. Do you have any other ones to offer? What do you know about orange peal ryne. ( if that is how you spell it..? Its not everyday a person uses it in a sentence :)

    Thank you,

    Del Rene :)

  67. Remember Calcium and Magnesium need one another to work properly. Mineral balance is the key when taking any supplement. The recommended ratio of calcium to magnesium is 2:1.

  68. I suppose if you’re paying over $8/dozen for eggs online you’d better use the whole buffalo! I’d definitely use this in a toothpaste or take it with magnesium and ACV so your body can get the most out of it.

  69. Thank you for making this information available. I am goign to begin saving my egg shells and try this!

    I think the Salmonella scare of eating raw egg yolks is over-hyped (I have been eating every day never got sick), but the concern for the shells is very real because of the direct exposure.

    Good tips to sterilize with boiling water and dry with oven.

  70. If you are relying on milk for calcium there are a couple of things you should be aware of. #1 The calcium content of milk (unless artificially supplemented) depends entirely on the diet of the cow, and modern dairy practices do not allow grazing the animal’s natural foods that contain calcium, ie green grasses. To raise butterfat content and facilitate industrial conditions dairy cows are fed mostly corn and soy meals, which are low in calcium. #2 Metabolizing butterfat requires calcium, as each fat molecule binds to two calcium molecules in the process. This means that drinking commercially produced milk could actually deplete existing calcium from your body, usually from the teeth and bones, or lock it into fat reserves.

    While I agree that egg shells are an excellent source of calcium, I question the availability of the mineral to the body in it’s raw form. I would suggest dissolving the ground egg shells in apple cider vinegar or lemon juice. This creates a form of calcium citrate that makes more of the calcium available to our digestive systems and diminishes the irritating effect the raw shells have.

    • Wonderful specification and RIGHT ON!, Keith! Thank you!

      • Keith you are so right about milk. Would like to add to yours a fact that cows milk was meant for baby calves. Also with corn and soy now being GMO and dangerous anyone who continues to add milk and dairy products to their diets is asking for more health problems. Also I would like to add that I have been misdiagnosed by doctors all my life and I am a grandmother. Since I started learning about eating healthy when in my mid 20’s I have enjoyed much better health. I am in my 60’s now and do not take or need any prescription drugs. My husband who is my opposite and visits a doctor 4 times a year is now on 3 drugs and is suffering bad side effects and can no longer sleep at night which is making him miserable and hard to live with. So no I don’t trust doctors except for broken bones and have kept myself healthy for years by reading alot of books and blogs and taking charge of my own health. I am sure alot happier and healthier than alot of people my age including my husband.

    • a khan yes–all of the receipts i’ve seen cal for acid neutralizing — just remember you have other choices–since a lab spill event in college i am allergic to vinegar, & i really dislike the taste and harshness of lemon.
      one better (to me) choice is lime. i suppose grapefruit might work but there are other problems with it. same with high acid tomatoes. there are a number of other safe sources of sour=acid–sour cherries really are sour-like wise apples, grapes, ant one of the sourest- rubarb.
      thank you-arthur

    • Here is a fantastic article on a variety of ways to get the calcium out of eggshells, including making calcium citrate with lemon juice (this is what I do… put the powder in lemon juice, wait 36 hours as it bubbles, and voila). I use a magnesium spray oil on my skin at the same time, and go out in the sun daily (live in Southern Cal)… not sure how to get natural vitamin K though. http://nourishedmagazine.com.au/blog/articles/how-to-make-calcium-using-egg-shells

  71. hello, can you please tell me what coffee grinder that you use? How long have you owned it? I use one and it doesn’t last very long when I use eggshells. Thanks for your help.

    • I’m imagining using my masticating Omega juicer. I already grind coffee with it…. any thoughts?

    • I use my Magic Bullet

    • Seriously, this is the first and last time I will come to this site. I have never seen such mean and hateful people in my life…over egg shells for goodness sake. I sure hope your children are not reading this ! Good bye !

      • Too bad, because there is some amazing info here that can be helpful for people. In any case, negativity is in the eye of the beholder. Have a sense of humor!

    • By using a mortar and pestle you can reduce the shells to a very fine powder that has no chunky or sharp bits. Just grind as normal and then if the bits are not small enough use the mortar and pestle until the consistency is to your liking.

  72. i have always used the water that i use for hard boiled eggs to make other things, like broth or used it for when i am making rice or anything that requires water because i can see the difference. by that i mean, some of the calcium leeches into the water and then i use it for cooking next time i need water.
    my nails and teeth show it.
    so i have no problems by keeping/storing the used egg shells and then grinding them down and using them in other things. can’t wait to see what happens when i add it to my bread.
    thanks.

    • Thank you Teresa for the great idea of using the water from hard boiling eggs! Great idea that I’ll start using.

  73. Years ago, when I was expecting my twins and was lactose intolerant, my OB/Gyn told me if I didn’t get more calcium, he would make me crush up egg shells and bake them into muffins. I was horrified! Now I think, “Cool!”

    And the best way to absorb magnesium is to run a hot bath, pour in Epsom salt, light candles, put on soft music, and loll around in the tub. :) It’s also the best way to greet your husband on Friday evening.

  74. We have always fed the shells back to our chickens and they produce the best eggs and their shells are very thick. We do bake them first and then just crush them but we don’t have to pulverize them..I think I will def try this my husband and I have a lot of joint problems ..hoping this helps.. (ran across another link that showed how to use orange/lemon peels to make vitamin C by just drying out the peel and then pulverizing them too..so sounds like I need a coffee grinder! ) Thanks for the post!

  75. What if you OVERCOOK the egg shells?? I left mine in oven after baking at 200 degrees but then my husband jacked oven up to 350 degrees and did not know the egg shells were still in there! The powder is slightly brown color with a cooked smell. Not unpleasant at all but wonder if the calcium is no longer viable?

    Also, I did not boil the shells before baking them, is that okay?

    • Hi Tara,

      Unfortunately, I wouldn’t use :(. You probably are OK not boiling the shells since you’ll bake them and kill pathogens but not sure on that :)

  76. How do you get all the egg whites off the shells? I tried making this the other day but couldn’t get all the egg white off…can I just grind it up with the shells?

    • Joanne… They are really slimey.. get as much as you can. When you boil and then bake them.. all of the salmonella (which is what you might worry about) goes away in the boiling process. (you will see little white bits at the top of the water that will rinse away. Then you bake them and that second heating process kills even more pathogens.

      If you are really worried and doing them in huge amounts, you can put them in tiny jars and boil the jars like you would a jam or jelly and that will seal the jar until you are going to use it. That will once again heat treat the product inside and kill more pathogens, while preserving it with an airtight seal. When you open it up a way to keep it fresh and away from bacterias is to keep it in the freezer. It is dryer than the fridge and pathogens are less likely to form again. :)

      Good luck!

    • I do as best as I can. You might actually be seeing the membrane which also contains minerals so good to include.

  77. We have done this for years and supplemented our garden soil. It adds much needed nutrients to the soil. We save the shells (and coffee grinds as well!) and till them in to the ground.

    We also spread rings of egg shells around the base of plants. It prevents any slugs from crawling to the plants. They eat the bits of egg shells and die! DON’T TOUCH MY PLANTS! :)

  78. I made it as suggested…it is a bit too crunchy for sprinkling on your breakfast…at leaset mine was. I plan to grind it again with my Mortar and Pestle.

  79. If this needs to be combined with magnesium – then how would you do it?
    How would you put into chicken soup?

    • Some articles say magnesium (plus D3 & K2) are needed for absorption of calcium, but just found article from U of Maryland saying magnesium and calcium compete for absorption. Need to do further research on this myself.

      http://umm.edu/health/medical/altmed/supplement/magnesium

      Re: chicken soup — you can probably put the egg shells in the soup. I put eggs in my chicken soup to make hard boil eggs, not knowing about the benefits of calcium leaching from the eggshells before reading this article today. Now would like to know how much calcium each egg/shell is leached into the water.

  80. Hi Dennis, I am not sure about whether or not the eggshell powder dissolving in liquid or not, having never tried it myself, maybe others will know. But one thing you can try if you have never, and it’s so easy if you don’t mind eating it, is black strap molasses. It has to be black strap, not just plain molasses. It is available in many places. In a small serving (1 Tb.) it has a good amount of calcium, iron, and I do believe it is also a good source of magnesium and other important nutrients. I like to drink it in a glass of warm milk, it is very yummy. Another way is in tea as a sweetener, or just in hot water, many ways to consume it in liquid form. I buy it in bulk and keep it in the fridge. Hope this helps, wish I was more knowledgeable about the eggshell powder.

  81. Have been grinding up egg shells to a fine powder for years and putting at the base of my plants. Water in well and making it bioavailable to them. Makes them stronger and better able to resist disease.

  82. I think I would make capsules filled with the ground egg shells using veggie capsules, or mix it in a smoothie.

  83. When I boil eggs for egg salad I save the water the eggs were boiled in. I cool it and use it to water my plants. I clean and save all my egg shells, crush them small and put them in the soil that grows my tomatoes….. I’ve never contemplated eating them myself… something to think about for sure.

  84. This is not totally on point but I found that if I put a whole egg in the soil when I plant tomatoes, they give me wonderful tomatoes that are bigger and better. Also, raising Chickens is very popular and not very hard to do, I have a flock of eight and I get about five eggs a day. I know for sure that they are fresh. Smiles

  85. I don’t eat a lot of dairy so I get my daily calcium from black strap molasses. Just a tablespoon can give you about 20% daily value of calcium, not to mention a good source of iron and many other nutrients. But I’m going to do the eggshell thing soon as well.

  86. Great now I don’t feel so weird. 14 years ago I was pregnant and refusing to drink milk as my first child had a milk allergy and that’s where I got my extra calories from with him. But with the second child I found myself munching on eggshells even when I was grossed out by the idea.

  87. I’ve taken to putting 1/2 tsp of eggshell into a shot of kumbucha. The kumbucha reacts with the eggshell and keeps it in small clumps (easy to swallow) so I’m not trying to down eggshell slush. Make sure to put dry into wet and not the other way around. After I drink the first shot I rinse the glass with a second shot of kumbucha to get all the shell goodness. I figure the extra acid from the kumbucha will help me digest the calcium better anyway.

  88. Im in the process of tapering off methadone. I juice every morning, eat very healthy, eat kefir grains and take apple cider vinegar. Im so happy you posted this because the methadone really messes with your bones and teeth : ( and my muscles always ache. Im going to do this! I hope I feel a difference, im sick of my body always aching. Thank you!

    • Most likely You need magnesium not calcium. Magtein is an easily absorbable form of magnesium. Good luck. Also depending on your metabolism some of the above that you’re eating might not be serving you at the moment.

      • I agree one needs magnesium more than calcium. As for magtein which is magnesium L- Threonate it was invented by researchers at m.i.t. It is the only form of magnesuim that crosses the blood brain barrier.It’s been clinically tested and it not only raises mag. levels it increases neural function in the brain, In other words it increases your abilities to learn.As far as calcium goes the have found that supplementing W/K vitamins prevents the calcuim from leaching out from your bones and going into your arteries and all different locations where it should’nt be. So all the extra calcuim supplementation is doing not helping the average person. Most mainstream doctors aren’t aware of these facts and according to some researchers you cannot get enough of the k-3 or k-7 which has a longer half life from your k-1 supplement. They have research showing a reversal of cardiovascular disease but it does not happen overnight it was a three year study. But the only lifestyle change was taking the k-3 vitamin

    • Good for you, Tristi! Keep it up, you’ll make it.
      When my son was getting off of prescription pain meds, and really suffering, I made smoothies for us every morning. Spinach, kale, broccoli, nut milks, honey, and whatever fruits I had on hand. Not perfect, didn’t know to get organic, or how to correctly combine ingredients, but it was a START, and it helped (so please, critics, hold your mean commentary). Everything is trial and error (that’s why it’s called the PRACTICE of medicine…they’re practicing…sometimes on US). Be gentle and listen to your body. You’ll make it!

  89. You are absolutely correct, too, Teri…..the only soy one should consume is fermented soy.

  90. Great idea!
    You also need to ensure that you have enough magnesium otherwise the body won’t absorb calcium properly. Many people are magnesium deficient. Easiest way is to take Mag Phosphate homeopathic tissue salts (supplements can be too strong and upset your stomach).
    I have used egg shells on plants before.
    Great post, thank you.

  91. I may have missed it reading above- but what if you hard boil eggs first- does that change the ability to use the shells for calcium? thanks,

  92. I rinse and crush my eggshells and throw them around my plants. I also toss my leftover teabags in my garden.

  93. Chickens seriously ARE cannibals. :) They’ll eat ANYTHING. They love meat of all kinds, especially chicken meat! Yes….I raise chickens. :)

  94. How long can I let the shells sit after cracking the eggs before cooking them for this process? A couple of days? or does it have to be right away?/

    • I just used up my eggs as normal so it took me about a week to have a dozen shells. Just put used shells back into egg carton and store in fridge.

  95. I made this and used a Magic Bullet knock off to process the shells but the powder doesn’t dissolve in water, it all sinks to the bottom because the grinds are too large. What can I use that will make it finer? I have been encapsulating it for now but that is tedious.

    • Dallas get a coffee grinder, thrift store, yard sales or watch the Sun. ads.

  96. Awesome info! We have organic, soy free chickens and I didn’t realize how much I can do with the shells. I was just composting them. Thanks for the tips.

  97. I live in Hong Kong and the best I can buy is organic, pastured and free-range eggs. I’ve emailed the company in New Zealand, they said their chicken mostly are fed on grass but are supplement with soy (and other stuff). Is a little bit of soy okay? Or absolutely no no for eating the egg shell?

  98. I don’t have my own chickens but the farmer I get my eggs from are pastured, organic, no soy or gmo and only $3.25/doz. Love them. I recently did this and added it to my remineralizing tooth powder.

    • Lucky! That’s a great price for eggs!

  99. OH and – do I need a dedicated coffee grinder for this? I don’t want my husband to be upset for ruining his coffee. :)

    • I actually just started making powdered eggshells a few days ago. I tried a blender and it really doesn’t work and I have a high-powered Blendtec. I have read about people using rolling pins and other things. But I figure, the cost of a calcium supplement–you’ll be saving a lot of money with eggshell calcium. I just bought a $15 coffee grinder, even though I don’t drink coffee. You may just want to buy a second one…

      • We use a spare coffee grinder for whole spices, could also use for egg shells.

    • Kat, I have been using eggshells in my coffee for 50 years. I just put one or two shells in the grinder when grinding my beans for 1 pot of coffee; it smooths out the bitterness. It Won’t ‘ruin’ his coffee at all.

  100. How much does a dozen eggs make? How best to consume? Does putting them in stock like several people mention up the calcium content of the stock?

    • A dozen eggs makes about 1/3-1/2 cup of powder. Yes, I would imagine putting the shells in stock would only up your mineral content, particularly calcium.

      I use our coffee grinder and just clean well. Since you only need to make every once in awhile, not a biggie. It grinds them well.

  101. I make egg shell water and drink about 1/4 cup a day. This is another great way to do it too!

    • I would also like to drink the calcium-fortified water. Do you know how much calcium you can get from each egg or shell that is boiled?
      Thank you in advance for your help.

  102. We’re raising soy-free pastured egg layers- they should start laying any time now. I’ll let you know when we have extra eggs to sell. :) In the mean time, I’m totally making this!

    • You go girl! I would LOVE to buy your eggs :)> You’re doing a great service by raising chickens the right way!

  103. This is great! Thanks so much for the tip and recipe. I’m a nursing mother to my 2 1/2 year old and since having her I’ve had serious muscle soreness- wondering if my calcium levels aren’t too low due to all the breast feeding?? I hope to find results with this and will let you know! By the way, is the water/shell concoction flavorless (I hope)??

    Natalie

    • DON’T FORGET LADIES – U CAN’T ABSORB CALCIUM WITHOUT ADEQUATE MAGNESIUM & FAR MORE OF AN ISSUE.

      • I hear you Karen! The great thing about eggshell calcium is that it also includes other micronutrients, the way nature intended. I also recommend daily use of a magnesium oil. XO

    • Hi Natalie,

      Yes, prolactin, which stimulates breast milk, also depletes calcium so very important for a nursing mama to get enough calcium.

      There is a very faint flavor. I simply mix the shells in a 1/4 c. of water and chug down. Don’t taste a thing that way.

      XO!

  104. Taking eggshell calcium gave me charlie horses in my foot, so make sure you are getting enough magnesium as well.

  105. My family has pet ducks and we did this for them since the females have calcium problems during laying seasons. Never knew it was ok for us to eat too.

    • Cool :) It even works with oyster shells too but harder to get!

      • Realy? That’s great news for me! My dad owns a wholesale oyster business, so I can get all of the oyster shells I want for FREE… And I can get them already in a powder form, which is awesome, because it would be extremely hard to get an oyster shell to a “dust” form… They are very hard and very thick!
        Only one question though… are oyster shells as effective as egg shells?
        I need to make sure I’m getting plenty of calcium, I don’t consume even half of the calcium I should.

        • I don’t know in humans, but we give oyster shell to the chickens, then their shells are harder and thicker. And I have seen oyster shell calcium supplements.

          • Yes, oyster shell is a good way to get calcium and is safe also. For years I’ve been buying oystershell calcium at CVS stores, its the best I’ve found.

        • You should start a business with the shells :)

  106. Awesome, I am definitely going to try this! I am always running low on calcium.
    By the way, I’m sure many girls here would love to see a video on what started you on your natural living kick all those years ago. Especially the food! I know many of us have started living naturally because of a health crisis, where we had to change or risk getting sicker. That has been my experience. It would be interesting to hear!

    • Thanks Mindy! Did you see my video on 6 tips to kick sugar? That kinda goes into my “come to Jesus” moment. I also am coming out with ebook very soon that goes into this as well. XO

  107. Awesome! I think I’m going to add this to tooth powder instead of buying the supplements to grind up!

      • I’m especially excited because a farmer sells “real” free-range, gmo-free eggs for $2.50 a dozen! That’s cheaper than normal eggs at the store! The yolks are so orange, they’re beautiful!

        • That is so true Monika. They’re much brighter and darker yolks and far more cheaper than even the lowest grade of eggs in a store. I love living near all these farms. And for anyone else looking for local farm fresh organic eggs in your general area, just try googling “farm fresh organic eggs *city/state*” you’re in and i’m sure you’ll find a spot. :) Happy egg hunting!

    • Thanks so much for the link, Courtney. Very helpful.
      Would you know how much calcium each egg provides in the eggshell-water? Prefer drinking it to consuming the eggshells. Thank you in advance for your help.

  108. Oh weird!! I never knew! It might take getting past a lot of mental blocks to do that though… seems kinda gross! But awesome that God created the world with abounding resources all around us!

    • Very cool indeed. You can also do with oyster shells!? A great, inexpensive way to get in some more minerals.

      • You are right! In fact, because producing an egg takes a lot of calcium from the chicken, oyster shell is often ground up and mixed in with the feed. Chicken handlers will examine the shells and if they are too light (for brown egg producing chickens) or too thin oyster shell is given to help the chicken replenish this supply. :)

    • I purchased a dozen of organic eggs from Kroger’s brand. These eggshells are brown. Is this okay to make calcium from? Thank you so much.

      • I think that brown organic eggs are probably the best. Their naturally brown when they come out of the chicken, so I think their okay, but it’s always good to check online in a few different places to make sure. :)

      • Brown eggs come from brown chickens, white eggs come from white chickens, and there are even chicken eggs that come out grey or green according to my brother who collects from his own chickens. The color of the egg shouldn’t matter as it is completely natural. I am curious, however, if anyone has made homemade toothpaste from the egg shells and does it work as well or better than the calcium carbonate you can purchase from the store?
