Calcium supplements are a very useful way of helping individuals who are unable to consume sufficient calcium from dietary sources. An extra 500-700 mg elemental calcium per day will suffice for most people. The cheapest, easiest way to achieve this objective is with a single calcium carbonate tablet containing 600 mg elemental calcium.

Calcium carbonate contains 40% elemental calcium by weight compared with 21% in calcium citrate. Although calcium citrate is more soluble and its bioavailability may be approximately 25% greater than that of calcium carbonate it is also more expensive. Calcium citrate was found to be less cost-effective than a calcium carbonate preparation in a recent study. Clinical situations where calcium citrate may be preferred over calcium carbonate include achlorhydria (calcium carbonate requires an acid environment to dissolve, calcium citrate does not), and in patients who need calcium supplements but have a history of kidney stones (citrate in the urine inhibits calcium oxalate precipitation).
