What do you do with your egg shells?

Eat them? Compost them? Throw them away?

I would appreciate knowing why you make that decision too.

It is a salt which is water soluble in slightly acidic medium (i.e. coffee). The better bioavailability has to do with consumption of CA ions versus calcium salt. If taken with a meal, carbonate is as bio-available as most salts.

hmm, Calcium Carbonate IS a salt. By protonating the base, you neutralize the negative charge on the carbonate ligand which leads to a lesser binding affinity to the calcium ion - this may be the cause for the better bio-availability.

If they're not from boiled eggs, just boil them and crunch them up. He doesn't eat many yet, but I'm hoping he will when he gets a bit older. I hear you can make an omelet for a turtle and include the eggshells, which I'm going to try. He's an Eastern Box Turtle. What kind do you have?

The carbonate being a Brønsted base will accept the hydrogen which causes the deprotonating of the acid allowing for the acid to form a calcium salt. This makes the calcium more bioavailable and also takes a little bit of the acidic edge off of the coffee.

Calcium carbonate is water soluble in dilute acids (i.e. coffee). A number of the acids in coffee can bind to the calcium ion to form a salt which would increase bioavailability but the water solubility should be enough.

The acidity of the coffee acts as an acid. But carbonate should have similar absorbability if taken with a meal.

Maybe a little bit. It's great for cheaper coffee (which I don't really drink) because it takes away the bitter bite. But when my coffees really fresh, I usually abstain for the first couple days to maximize enjoyment. But I'm a pretty big coffee snob. Probably not noticeably for most folks. *shout out SEATTLE*

I grind them and mix with lemon juice to make calcium citrate and then take 1/4 tsp a day. Store in refrigerator. I do this to make the calcium more available for absorption, its also dependent on stomach acidity so eat this when stomach acid is highest earlier in the day.
