Calcium is essential for maintaining the necessary level of bone mass to support the structures of the body. The body is constantly using calcium for the heart, blood, muscles and nerves. Calcium is also lost through normal bodily processes such as waste and the shedding of hair, fingernails, sweat and skin. Generally speaking, the body requires a little more calcium as it ages. For example, a 1 year old only needs 270 mg of calcium while a 7 year old needs 800 mg. At age 50 or older, you'll need 1,200 mg. Calcium is a necessary part of the body at all times. Taking in additional calcium is required for those with a deficiency. Some people take extra calcium while pregnant or lactating.
