Egg shell calcium?

Anyone use calcium from egg shells? I've been reading online that the calcium is more easily absorbed and it can be made at home with a coffee grinder.

I've made it before and consumed it, but not since WLS. Mostly because I use our egg shells from our chickens and they just have finally started to pick up production now that it's spring. It's not hard to do. You can over do it with the amount if you aren't careful though I've heard. I have mostly just baked them into things.

We feed our egg shells back to our chickens and their eggs have harder shells now than they did when we used ground oysters...I imagine that it would be hard to figure out the amount to make the three 500 mg doses a day my vitamin plan requires.

Most sites are saying between 700-800mg of elemental calcium per Teaspoon.

I was thinking more of just replacing one dose per day, so 1 to 2 doses of calcium citrate, and 1 dose of egg calcium.

I read that it is calcium carbonate - aren't we supposed to have calcium citrate?

According to Wikipedia, chicken eggshells are made of 95-97% calcium carbonate. From everything I've learned, DSers should not take calcium carbonate, only calcium citrate.

Was trying to find a medical site but couldn't find one that gave the makeup of the eggshells.

I was just doing research mostly on "natural health" websites and PubMed.

But from everyone's feedback, I'll just stick with calcium citrate.

I am not sure about VSG patients for Cal Citrate but as a RNY patient my surgeon only says for me to take Citrate

We use our eggshells for our chickens and for my gardens.

As previous posters have commented, eggshells are calcium carbonate. I know from how I prepare it for my chickens, that if I treat it with vinegar, it will become "calcium citrate" but even then, it's only about 20% elemental calcium. I am an RNYer -- I don't know about DSers -- but we need citrate for absorbability... and at 21% elemental calcium, it really isn't a great source compared to relatively low cost supplements.

Additionally, one will need magnesium for the calcium to work. For every 2 parts of calcium there be at least 1 part of magnesium, not to mention all the other minerals such as Boron and Silica as well as D3 and K2 (as MK-7) --

Otherwise, ingesting large doses of calcium -- especially carbonate, can contribute to an array of issues such as cardiovascular and kidney problems.

Frankly, I do not see the advantage, nor do I see that it's more "absorbable" overall.
