Answer

Commonly used calcium supplements include calcium carbonate and calcium citrate. Calcium carbonate is generally less expensive and is recommended as a first choice option. Calcium carbonate has better absorption with food, as opposed to calcium citrate, which is better absorbed in the fasting state. Also, fewer tablets are needed with calcium carbonate than with calcium citrate.
