Calcium from egg shells?

Commented on April 03, 2014
Created April 02, 2014 at 6:40 PM

I don't consume dairy so I usually end up a bit short on calcium, and even then a lot of my calcium comes from dark greens. ( Apparently not a very bioavailable form)

Would consuming egg shells be a viable method of increasing calcium intake? If so what preperation would be required?

I haven't exactly tried it, but I imagine grinding them down would be the best for palatability. I've also seen it mentioned that you may want to cook them to kill off any bacteria? Not sure how required this would be? I've also seen it said that this can be hard on your gut?

So, Is this ideal, what preperation would be needed and what quantities would be good per day? ( E.G. 1 egg shell = 200mg or W/E )

I'll pick this as the correct answer, even though I'm fairly sure it was plagiarized!

Note: One of the articles mentioned baking them after for drying as opposed to letting them sit out overnight. ( May be a bad idea if you intend to store them long term? )

Paleot you should really read the links you post, in this context they could certainly confuse people who don't read them. While the catchy title says you shouldn't 'supplement calcium' the article ends with them saying their own multivitamin contains calcium...for supplementation...

They say people need k2/D/Mag to put calcium in its correct place and that people who supplemented calcium, or even people who didn't would accumulate calcium in places where it shouldn't be - Gut/arteries/various biofilms - presumably they wern't supplementing K2/D/Mag.

That sounds suspect to me...

'Buddhist nuns', how many of those could they possibly have studied?

Buddhist nuns who ate a vegan diet and consumed less than 400 mg of calcium daily had the same bone density as non-vegetarian women who consumed 1000 mg of calcium each day.

If you have your other electrolytes in balance, without many phytates in your diet, and D3 and k2 cofactors, calcium will end up where it needs to be. Exercise increases bone density.

I operate under the opposite assumption. With your other electrolytes in balance, you should have adequate calcium. Without phytates in your diet, you should be able to absorb it. With adequate d3 and k2 cofactors, it'll go where it needs to go. And with exercise, you'll increase bone density.

Jaminet recommends bone&joint broth/soup for calcium (& other stuff, phosphorus, collagen)...i wonder if supplementing with 'bone meal' would work just as well for calcium and phosphorus (if you do not do the broths/soups)

Would appreciate more information on this if you have it.

I'm under the understanding that the RDA was just or is going to be raised for Calcium.

My understanding is that the RDA for a male adult is about 1g/Day with something like 750mg probably being a bit better, to prevent prostate problems I think it was? That being said I'm at less than even the lower number and part of that is from not very absorbable forms - Leafy greens.

I'm totally inspired to try making egg shell powder too! I've read that a coffee grinder works well.

Seems like a great idea. Kinda reminds me of how some Ca+ supplements are made from crushed oyster shells. And our chickens like eating egg shells.

There are lots of sites that explain creating egg shell supplement powder. I'm seriously gonna start doing this using a coffee grinder!

Well, you might get a good amount of calcium from one eggshell, but i don't think it is necessarily a concern unless you are eating it every day. Besides, you could always cut it with something else, like coconut flour for example, that way lessening the dose while simultaneously getting more uses out of fewer eggshells and not having an end-product that might be excessively crunchy or hard.

Yes to the first part, but people mention you may want to cook them to kill bacteria and to dry them out. Probably more important to dry them if you're intending to store for some time. I doubt they would make a good breading...sounds questionable to me. But lmk if it works. :D

From something I've seen 1 egg shell/1 Tsp = 800mcg calcium. So another concern with using it as a breading would be super high doses of calcium.

Many people consume Egg Shells for Calcium.

Here are some ingredients and equipment’s that are required

1) Organic Pastured Chicken Eggs

2) Stock Pot

3) Coffee grinder

4) Mason Jar with clean lid

Simple Steps:

1) When you have collected sufficient amount of eggshell collect them and remove any white stuff that might have being stuck. Note that you should avoid removing membrane.

2) Use the stock pot where fill it with approximately 6 cups of water and bring it to boil.

3) Boil it for 10 minutes

4) Drain the shells

5) The next step will be collect the boiled and cleaned shell to spread it n glass or stainless steel baking sheet and let dry overnight

6) Once completed you can grind these shells in the coffee grinder until they are pulverized into a granular form. Continue until all of your shells are powder.

7) You can consume Eggshell Calcium everyday. One tsp contains 800-1,000 mg of Calcium. Consume it by mixing small amount of water with a meal.

I've wondered about adding eggshells to bone broth - the long slow cooking and the vinegar seems like a good combination to extract the mineral content. I can't stomach the idea of eating them ground up.

I think there is a reasonable argument that the calcium RDA is higher than needed. This may have been due to Dairy Council pressure, when the RDA table was being prepared. You don't need dairy to be healthy and you don't need egg shells.

You know, this post just gave me an idea. How about putting the shells in a food processor and breaking them down until they turn into a fine dust, similar to bone meal. This powder could probably be used to add to things like fish cakes, stews, nut butters, paleo meatloaf, burger patties or meatballs, chili, or something else that could benefit from some form of thickener or that might easily disguise the chalkiness. Heck, it might even make a good "breading" substitute, since breading is so often used to add crunchiness, this calcium dust might do the trick. Like cod "breaded" with egg shell meal and fried....you know what, I think I'm going to try this.
