A member asked:
Is calcium carbonate a better calcium supplement than calcium citrate?
5 doctors weighed in across 2 answers
No: No, the only difference is that the former is better taken with food whereas the latter (calcium citrate) can be taken on an empty stomach.

Depends: While both are common, some find calcium carbonate more constipating and it may not be as well absorbed. Others can tolerate calcium citrate better and it may be better absorbed. The body only absorbs about 400-500 mg at a time so do not dose all at once.
