Calcium in diet - Overview

Alternative Names

Diet - calcium

Definition of Calcium in diet:

Calcium is the most plentiful mineral found in the human body. The teeth and bones contain the most calcium (about 99%). Nerve cells, body tissues, blood, and other body fluids contain the remaining calcium.

Function:

Calcium is one of the most important minerals for the growth, maintenance, and reproduction of the human body. Calcium helps form and maintain healthy teeth and bones. Proper levels of calcium over a lifetime can help prevent osteoporosis.

Calcium helps with blood clotting, nerve signaling, muscle contraction and relaxation, and the release of certain hormones. It is also needed for a normal heartbeat.
