If your diet is inadequate in calcium, a supplement may be necessary. However, when it comes to calcium supplements, some may be good but more is not better.

The upper level for calcium has been set at 2,500 milligrams daily to avoid hypercalcemia (hyper = too much; calcemia = calcium in the blood) or too much calcium in the blood, subsequent impaired kidneys, and calcium deposits in the body.
