Calcium
Calcium is one of the most important minerals for the growth, maintenance, and reproduction of the human body. It is essential for the formation of and maintenance of healthy teeth and bones. The bones and teeth incorporate calcium into their structure; like other tissues in the body, bones are continually being reabsorbed and re-formed. Calcium is also responsible for blood coagulation, transmission of nerve impulses, muscle contraction and relaxation, normal heartbeat, stimulation of hormone secretion, activation of enzyme reactions, as well as multiple other bodily functions. Many foods contain calcium, but dairy products are the most significant source. Foods such as yogurt, cheeses, and buttermilk contain an efficiently absorbed form of calcium. Calcium is the most plentiful mineral found in the human body, accounting for 1.5% to 2% of an adult's total body weight.
