Calcium is the most abundant mineral in the human body, 99% of which is stored in the bones and teeth. Dairy products are the main source of calcium in the United States.
Uses
Humans require calcium to perform many necessary bodily functions, including blood vessel contraction and expansion, muscle contraction, and the secretion of hormones and enzymes. The body maintains a constant level of calcium in its fluids to carry out these functions properly.
Importance
Since the body does not create calcium and it is constantly being shed in skin, hair, sweat and bodily wastes, it is imperative that people get the proper amount of calcium in their diet. If you do not get enough calcium in your diet your body will break down bones to get the needed mineral.
