Calcium, known as the knitter because it "knits" bones back together, is one of the seven essential macrominerals needed by the body. 1% of the calcium in the body is used to support critical metabolic functions. The other 99% is stored in the bones and teeth where it supports their structure and function.
Calcium is needed not only for the body but also for the mind. A person considered to be "high-strung" or a person with an inferiority complex may need calcium.
You must have proper levels of vitamin D for calcium to be absorbed.
