Before finding that, I found you can rinse eggshells, leave the membrane in. Boil for 10 min, then bake at 200F for 15 minutes before putting in a coffee grinder. 1/2 tsp of powder is 400 mg so I just added to boo balls accordingly.
If you search on the board I think you can use a certain kind of tums in an emergency til you get something better.
