Calcium absorption: Calcium citrate is readily absorbed by the intestine in the absence of acid in the stomach whereas calcium carbonate is poorly absorbed in the absence of acid. However calcium carbonate is absorbed if taken with a meal.

Absorption: Citrate is a little easier to absorb and more calcium dense. Both work if you take enough, take them properly, and make sure you get in at least 2, 000 units of vitamin d3 a day. If you truly have osteoporosis, your doctor may want you to take additional medication as well.
