Calcium is the most abundant mineral found in the body, with 99 percent stored in bones and teeth. Calcium helps your body perform essential functions including muscle and blood vessel contraction, as well as hormone and enzyme secretion, explains the Office of Dietary Supplements. The Recommended Daily Allowance of calcium for adults aged 19 to 50 years old is 1,000 to 1,200 milligrams daily.
However, too much calcium in the blood -- hypercalcemia -- can be dangerous, and if that happens your doctor prescribe a low-calcium regimen. There are a number of healthy foods available for you to choose from.
