is a calcium supplement necessary
It makes up about three percent of the earthâs crust and is a basic component of most animals and plants. Our bones serve as a storage site for the bodyâs calcium, providing this mineral to the bloodstream for use by the heart and other organs. Eating a diet rich in calcium helps to restore it to the bones; supplements can help as well. Why is it necessary? Calcium is known mostly for its role in building and maintaining strong bones and teeth, but it is also required for proper functioning of the heart, muscles and nervous system. It plays a role in maintaining normal blood pressure, regulating blood clotting, and preventing cancers of the digestive tract.
