A member asked:

Which is better for bone health: calcium carbonate or calcium citrate? specifically, which one has a higher chance of causing kidney stones?

Neither: Recent studies have concluded that calcium in any form has no value in building bone or preventing bone loss.

Calcium: Both of these will supply calcium to your body and kidneys. Calcium citrate is better absorbed than Calcium Carbonate. Calcium citrate supplies citrate, which is helpful, but the amount is very small. Carbonate is not well absorbed so will not affect urine pH. The total mg of calcium matters as well as how much fluid you drink per day and other diet content. Avoid salt, meats, and drink 4 L/day
