I tried it once but didn't grind the eggshells fine enough. It was very gritty, but otherwise didn't taste bad at all.

I do it from time to time. Make sure you put a large enough piece so it is easier to fish it out. My grains grow like crazy with or without eggshell. What to do with all those extra grains? I feed my cat with extra milk grains, but he does not like water grains at all...

Kefir thrives when given extra minerals.

I've heard of people adding egg shell powder to straight lemon or lime juice and letting them dissolve into a goop, which makes calcium citrate and is more bioavailable than the calcium carbonate of regular egg shells. The calcium also neutralizes the acid from the citrus juice, making it less corrosive to your teeth. A half teaspoonful should be plenty to meet your daily calcium requirements.

Save them and throw them in your garden! They are awesome nutrients for soil to make more fruits and veg!!!

Great suggestions! Some water kefir recipes call for boiled egg shell to increase kefir's mineral content.

I bake my used egg shells and feed them to the chickens for calcium.

I add teeny bits of washed eggshell to my water kefir sometimes. The grains seem to love it. I don't like it so well, as they get super slimy and fishing it out after is not my idea of fun.

Do I win the prize for spectacularly missing the point of the question and most tangential answer?

I added egg shell calcium to my diet but they gave me a really painful stomachache. I made sure to boil them and sanitize them but they still messed me up pretty bad.
