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:


  • 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.


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

    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 :D 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 :)

    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 did it take me there.

  7. PooPooPeeDoo January 1, 2014 at 7:49 am

    You people are so engrossed in your own fucking bullshit…

    Do you REALLY need to have extra added to a reasonably good diet? Probably not.

    Calcium Carbonate? Buy a bag of builders lime (slaked lime) add water and then stir every few days and scrape off the floating crystals – that is the calcium hhydroxide that has absobed CO2, and has now become calcium carbonate.

    Buy a block of limestone… small amounts of it hit with a hammer into a sand like consistency – will dissolve in the acid in the gut.

    “Ohhhhhh Ohhhhhhhh fucking hygene! – Just hard boil a fucking egg and eat it whole – shell and all….”

    Fuck you stupid americans.

      Again, do your research:)
      It’s not calcium carbonate. So funny how ignorance can get ya every time.

    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!

    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.

    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

  17. Debbie Thomas October 27, 2013 at 11:08 pm

    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

  20. Mike October 12, 2013 at 11:17 pm

    It’s sad to see what the Internet has to offer these days. Yes any idiot knows that egg shells contain calcium. But those who profess knowledge can’t even write in proper grammar and punctuation. Who’s going to beleive a professor who can’t communicate effectively? Nobody! Including this man. Doesn’t take a rocket scientist? I am a rocket scientist and these posts are garbage.

  21. Kate October 12, 2013 at 11:42 am

    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 :)

  22. Norma October 10, 2013 at 11:49 am

    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.

    • Lisa November 2, 2013 at 10:48 pm

      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.

  26. Chris Lion October 7, 2013 at 12:39 am

    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.

    • Sara Jo Poff October 9, 2013 at 5:28 pm

      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!

  27. Rebecca Langley September 26, 2013 at 3:41 am

    Hi there, and thanks for the post. Part of your article says, “In animal and human tests, eggshell calcium shows increased bone density, less arthritic pain, and even stimulates cartilage growth.” Can you provide a link or citation for those tests? Thanks!

  28. Nick Beck September 2, 2013 at 9:55 am

    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.

  30. Olivia August 24, 2013 at 2:56 pm

    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.

  31. Alpha Delta August 18, 2013 at 2:25 pm

    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.

  32. ew0054 August 11, 2013 at 6:52 pm

    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.

  33. Keith Evans August 10, 2013 at 12:15 pm

    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.

    • Analita Kruse August 16, 2013 at 10:03 am

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

      • Keith Evans August 20, 2013 at 8:15 pm

        One of the great lies in the industrial food system is the calcium “hook” to sell milk. Firstly, even raw milk from industrial producers has very little calcium due to conditions I described, but secondly, this marketing is mostly aimed at children, and often along with heavily sugared cereals or drink mixes. The damage done to growing bones and teeth from this lie is unconscionable and can only be viewed as purposeful. This information is not new, nor a secret.

        I have no degrees, such as the lab staff in these companies have, and I can figure out how dangerous and false this campaign is. Even our government has weighed in to support this deception, which makes it doubly worrisome. The big winners, aside from the commercial dairy industry, are dentists and other health care providers who have reaped the financial rewards of a misinformation campaign that has made an entire generation less healthy.

        • BJ October 8, 2013 at 12:55 am

          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 January 6, 2014 at 11:05 pm

      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.

    I have to agree with some of the Facebook comments- I’m not sure I’d make a habit of giving out advice on supplements unless you are a pharmacist or physician.

    • Vicky August 10, 2013 at 10:24 am

      Really? Doctors know nothing about nutrition. And it doesn’t take a rocket scientist to know there is calcium in eggshells.

    • Keith August 26, 2013 at 10:21 pm

      Don’t be so ignorant, Sarah.

      • Sarah August 27, 2013 at 6:42 am

        Come on guys… Assuming that people who read nutrition blogs are better learned about all things health related is rather broad-sweeping, as is assuming that physicians and pharmacists “know nothing”.

        Sure- some may not be experts in nutrition, but others may have more understanding than you think; the key to optimizing your health is to find knowledgable and trustworthy doctors, as well as arming yourself with as much knowledge as possible. Get recipes and ideas from blogs, but ask a trusted source before supplementing (which should be advised by any blog posting any health related information, lest someone have a reaction and file a law suit. It happens, one reason why ALL supplements have the same disclaimer on the bottle. Don’t be so ignorant). The world is not black and white- you people can’t possibly think that all doctors are these evil robots with a mission to fill you with disease, right??

        Again…don’t be so ignorant. ;)

        • Jeff September 25, 2013 at 12:40 am

          Sarah, you know damn well if doctors suggested proper nutrition to all their patients they would be in trouble fast with the AMA which was founded on evil intentions. There are many documentaries and facts to back up the fact that ND’s are way more successful at treating chronic problems yet they are called quacks by the quacks. MDs are are the quacks in the field of nutrition and NDs are the masters! As more people realize this, less MDs will be needed since their wheel house is trauma care and infectious diseases not health care. If you want to take responsibility for your own health visit “fire your md now” …it’s a website.

        • Sheri November 2, 2013 at 9:16 pm

          yes let’s all do what Doctors say and drink the kool-aid like Doctor Sarah is trying to get you to do there are no trusted doctors they all have been taught and misled by the old doctors and have no idea how much chemicals they are making us ingest is causing all the cancers in the world, like vaccines all lies people just follow God and rid your life of as many chemicals as you can, do the research like cereals, tuna, salmon, all products that are made plus now all our natural foods being sprayed or ingested with chemicals try to grow and make as many of your own food as possible and follow God and that will rid your ENTIRE life of all toxins, Like you say Sarah those that call the kettle black hmmmm don’t be so fooled by society.

        • Julia January 11, 2014 at 1:09 am

          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

  35. Shaun June 18, 2013 at 8:37 am

    Doesn’t the boiling cause leeching of calcium into the surrounding water? If you bake for 10 minutes at 212deg would you not accomplish the same goal w/o the calcium leeching?

    • John July 9, 2013 at 12:59 am

      No, definitely not. There is not nearly the same amount of energy transfer in an oven as there is in boiling water. I believe that the oven equivalent is 200C for 2 hours.

      • tb August 22, 2013 at 1:50 pm

        “The article clearly has a pasteurizing step, which is the 10 minute boil.” – John July 9, 2013 at 1:07 am

        Boiling is way beyond pasteurization, and while your comment on the oven heat transfer may or may not be accurate, this recipe includes a boil which will likely leech out minerals / nutrients.

        If you don’t know the different between pasteurization vs boiling, you have, as your would say, no business giving advice on this subject.

        And consider taking a chill pill – both women asked valid questions. When did you stop beating your wife?

        • Lisa truitt September 6, 2013 at 8:45 am

          Yes I do think they are evil robots. As robots I don’t think they are intentionally steering people toward useless toxic approaches that cause disease but they do so nonetheless.

          Eggshells are a wholesome and very effective calcium source. They have been used by mainstream medical researchers and found to be the best calcium for reversing osteoporosis. The calcium from eggshells goes into bones without raising serum calcium levels which is what you want.

          There is knowledge galor available on nutrition and supplementation these days so that your average person has the ability to be far more knowledgeable than the vast majority of doctors are. Personally I don’t trust doctors. They are simply bent on getting you on drugs and selling you expensive and most likely harmful surgeries, tests and procedures. The premises that they base much of their diagnosis and treatment on such as the lipid hypothesis are out in left field and as a result millions of people are needlessly put on medications that harm them.

          As far as being sued goes, that is why information purveyors have a disclaimer. Unfortunately we live in a litigious society full of people who don’t like to use wisdom and common sense and caution in their own care. They don’t want or know how to exercise self governance and be responsible for themselves. Instead they want others to be responsible so they have someone else to blame and to make pay for anything that could go wrong. They want absolved of any and all responsibility for themselves.

          The idea that only doctors, or supposed experts in any field for that matter, should give out information, is the stupidest and most scary, bizarre idea I have heard in a while. These people most often have every incentive to tell you the opposite of the truth because of financial gain. Let me give you an example. Heart arrhythmia is most often caused by mineral deficiency, mostly magnesium but others like potassium can play a role. ERs give people magnesium sulphate otherwise known as Epsom salt IV for heart problems. Then they send the person on to get unnecessary drugs and surgeries because treating the cause, magnesium deficiency, is not lucrative for them. Most people don’t even know they got a magnesium drip in the hospital and that this is what stabilized them because it was actually treating the cause. They don’t know that they could continue to supplement magnesium and not need the drugs and surgeries and all the medical monitoring needing extra visits and tests etc etc that go with that. This happened to my mother in law except I told her what was going on. They wanted to do heart surgery on her for Gods sake. She went to the surgeon and told him about magnesium and that she wanted to try that first before such a drastic thing as going under the knife. He LIED and told her that magnesium wouldn’t help her and that she needed the surgery and tried to talk her into it. She turned him down in favor of magnesium and has not had another episode since. I say he lied because it is widely known medically that magnesium stops heart arrhythmias and heart attacks. That is why it is used when people with these afflictions are taken to the hospital. But in a system that only cares about selling you expensive patentable drugs and procedures because there is only small money to be made from natural, nutritional treatment which takes care of the cause and cures you so that you don’t need constant disease management and monitoring, you will be lied to every time. And you are telling me these are the only people that should be trusted for nutritional info! You have swallowed the cool aid. They have got u right where they want you.

          • Sarah September 6, 2013 at 10:25 am

            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!)

            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.

  37. teresa May 21, 2013 at 11:29 pm

    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.

    • Dena October 19, 2013 at 11:54 pm

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

  38. samantha May 19, 2013 at 4:32 am

    You really need to proofread this. Nowhere does it say to use pasteurized eggs. That is SO important. So many people could get dangerously ill. You put “pastured eggs” not the same thing. Please change this. A real scary mistake, and if you meant not to include pasteurized- that is even worse!!!

    • John July 9, 2013 at 1:07 am

      I don’t know why you brought up pasture eggs, since this has absolutely nothing to do with pasteurized other than sounds somewhat similar. The article clearly has a pasteurizing step, which is the 10 minute boil. If you think this is not enough to make them safe, then you shouldn’t really be eating any eggs.

      • Lauren November 16, 2013 at 2:04 pm

        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.

    • Eric August 9, 2013 at 1:12 am

      Boiling and Baking the Eggs removes the Mineral Oil and any bacteria that might be on the shells, making absolutely any and all forms of Egg Shells consumable as a Supplement.

    • Vicky August 10, 2013 at 10:20 am

      I don’t even know what to say. Do you not realize that pasteurization is nothing more than cooking? And these are cooked twice so what’s the big deal? And you want PASTURED eggs because they will contain many times more nutrients than confined, caged, soy-fed chickens can produce.

    • Barbara October 9, 2013 at 5:58 pm

      How ridiculous samantha. For a start the egg shells are boiled up and then baked in the oven.

    • karen October 11, 2013 at 10:42 pm

      really? I hope samantha has learned SOMETHING

  39. Julie May 17, 2013 at 7:23 pm

    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.

  40. Rod April 1, 2013 at 4:37 am

    I’m fairly sure your body cannot digest eggshell powder (or chalk, the other name for calcium carbonate). It must be dissolved in acid first (lemon juice, vinegar). Then dilute the acid so you can drink it.

  41. wanda March 4, 2013 at 7:33 am

    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 sounds like I need a coffee grinder! ) Thanks for the post!

  42. tara February 22, 2013 at 6:39 pm

    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?

    • Genevieve February 26, 2013 at 10:56 am

      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 :)

  43. Joanne February 15, 2013 at 10:52 am

    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?

    • Liz February 15, 2013 at 11:12 am

      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!

    • Genevieve February 18, 2013 at 1:23 pm

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

  44. Liz February 14, 2013 at 5:14 am

    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! :)

  45. Shelly L February 9, 2013 at 11:27 am

    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.

  46. Susan January 28, 2013 at 9:11 pm

    I learned in biology that you can’t cross kingdoms when mammals are trying to get their minerals. We have the mineral kingdom and the plant kingdom. Mammals can’t absorb or utilize minerals well without the aid of a plant breaking it down first. I would never consume oyster shells for this reason. I wonder how this relates to calcium from eggshells? Also, calcium carbonate has always been an inferior source of calcium. I wonder if it is more acceptable from an eggshell source than the cheap calcium supplements out there made from calcium carbonate?

  47. Allison January 28, 2013 at 6:17 pm

    The recommended daily doses of most vitamins far exceed what a body actually needs. The reason the calcium recommendations are so high is because it used to be assumed that one’s calcium intake would be supplied mainly by milk products. Calcium molecules in cow’s milk are huge and not well absorbed and assimilated. It was found that one had to consume 1200 mg of calcium in milk to ensure a daily absorption of about 300 mg. If we actually assimilated 1200 mg of calcium, our joint cartilage would calcify and we wouldn’t be able to move. (This is according to the USDA for whom I worked. This and many, many other lies about nutrition were openly available to staff but not the public. Another one is that all nutrition labels are based on raw ingredients, not the packaged, processed result.)

    I hail from Pakistan where the chicken meat is usually broiler so can the egg produced by the broiler chicken fit for getting calcium

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

  51. Dennis Champagne January 18, 2013 at 5:48 pm

    1. Mom when she was a baby, her small intestines were removed. Does egg shells in powder form turn into liquid when boiled. Cause if not in liquid form her body will not disolve the powder. She is also experiencing arthritis and what I hear can help her.
    2. You keep saying you need magnesium with the eggshells, but also here people taking it with coffee. Again does it melt in the coffee like sugar when in powder form, and does coffee have magnesium in it.
    3. 2007 I was in a really bad accident. Now 2013 noticing my calcium serverely depleting, need to be on a calcium regiment. Thinking might help my bone structure, and help my teeth be healthier as I have to take heavy medication oxy cotton 30ml – 3 times a day. Maybe taking calcium will help.
    4. I can’t be in the kitchen for long as I can’t stand still for long periods, asking if you can give me maybe quick and easy recipies.
    Thank you for listening

    • Clarice O'Brien January 19, 2013 at 6:41 pm

      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.

  52. Shelly L January 18, 2013 at 2:34 pm

    So confusing…there are always differing opinions and its just guess work as to which approach a person decides to take after reading all the posts. My hubby has said for years that egg shell would be good calcium and that oyster shell would not be good, after all, it would be very difficult to add it to your regular diet without a lot of intervention. Egg shell on the other side seems quite easy. As long as a person knows to also add magnesium, it sounds like a good idea to do this.

  53. Nancy January 18, 2013 at 9:30 am

    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.

  54. Linda January 18, 2013 at 6:11 am

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

    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.

    My 3yr old son has 22q11.2 deletion syndrome and his body throws off calcium really bad. Hes already had 4 teeth pulled due to it. Is egg shell calcium easy to absorb? And do you know what other nutrients the egg shell is high in?

  57. Pamela Lukasek January 17, 2013 at 10:10 pm

    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

  58. Clarice January 17, 2013 at 9:59 pm

    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.

  59. Karen Pruneau January 17, 2013 at 9:54 pm

    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.

    the whole vegetarin chicken feed and chickens is insane. Free range chickens eat bugs and grubs worms and ticks etc. My chickens free range and if a chicken sees blood on another chicken regardless they attack, they Dont need teeth to do so. They will tear apart another injured chicken due to the pecking order with there beaks and they even made red glasses in the earlier years for chickens so they couldnt tell if another chicken was bleeding. The healthiest chickens are those feeorganic grains not vegetarian and that free range..Your information is false sorry… your research….vegetarian is not always best or ment to be for the animal .You want what is best for your family buy farm feesh organic feed free range eggs, if not keep buying vegetarian but your family will get no benefits out of the eggs due to the lack of protein .

  62. Sarah H December 22, 2012 at 5:47 pm

    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.

      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.

    unhulled sesame seeds = A quarter cup of raw natural sesame seeds has 351 mg of calcium while one cup of non-fat milk has 316.3 mg, and one cup of whole milk has only 291 mg of calcium. Plus, they are alkaline whereas milk is acidic.

    raw, fresh carrot juice = mega calcium per glass than 1 glass milk (One pound of carrot juice is equal to 20 pounds of calcium tablets as far as the active calcium is concerned)

    • Cut the VeganFalsehoods February 8, 2013 at 8:38 am

      NO, carrots are NOT a good source of calcium! Vegans like to think so though. Use the site called NutritionData for actual numbers for any type of food. 16 oz of carrots (a whole pound, about 500 grams using metric), has only 168 mg of calcium.

    • Posted from above December 22, 2012 at 2:34 am

      Homemade Eggshell Toothpaste

      ¼ c. Egg Shells or Calcium Magnesium Tablets (Ground up)
      1-3 Tbs Coconut Oil
      1 Tbs. Baking Soda
      ½ -1tsp. Castile Soap (Optional but I find that it adds some smoothness)
      10 Drops Peppermint Essential Oil
      4 Drops Tea Tree Essential Oil

      1. If using egg shells, give them a quick rinse and bake in the oven at 400 F for 15-20 minutes.
      2. Grind up the shells or tablets until powdery fine. I use my coffee grinder for the shells and my food processor for the tablets.
      3. Mix the ingredients in a small bowl, adding coconut oil until it is the smooth consistency that you like. * I find that it takes more with the calcium magnesium pills than the eggshells.
      4. Store in a small jar and use a small spoon to scoop it on your tooth brush.
      5. You can add different essential oils that are said to promote tooth health such as fennel, clove, rosemary, thyme, oregano, eucalyptus (to name a few).

      - Inexpensive to make
      - Natural, healthy ingredients with no additives or sugars
      - Cleans teeth well
      - Fights Sensitivity
      - Whitens without harsh chemicals
      - Stores well

      - You have to make it and it doesn’t come in a handy tube.
      - Depending on the temperature, the coconut oil solidifies. (you can soften it again by mixing it again)
      - Doesn’t foam like we are used to with toothpaste.
      - Isn’t sweet
      - Is a little messier in the sink.
      - Tooth brushes (esp. childrens) get caked if not rinsed properly.

  67. Elly December 19, 2012 at 3:33 pm

    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.

    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.

      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…

      • Clarice January 17, 2013 at 10:08 pm

      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.

  77. Kat October 2, 2012 at 2:15 pm

    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?

    • Genevieve October 2, 2012 at 8:50 pm

      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.

    • Genevieve September 27, 2012 at 6:59 am

      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.

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

    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 :)

    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!

    • Genevieve September 27, 2012 at 7:03 am

      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

  84. Monica September 25, 2012 at 1:47 pm

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

      • Monica October 10, 2012 at 5:43 pm

        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!

        • Genevieve October 11, 2012 at 1:13 pm

          Lucky you! That’s awesome!

  85. Cyndi September 25, 2012 at 12:00 pm

    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.

      • Vera October 5, 2012 at 12:37 pm

        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. :)

    • Adell March 7, 2014 at 8:57 am

      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.
