Calcium is vital for the formation of strong bones and teeth and for the maintenance of healthy gums.
It is also important in the maintenance of a regular heartbeat and in the transmission of nerve impulses. The movement of calcium into nerve cells triggers the release of neurotransmitters at the junction between nerves.
Calcium lowers cholesterol levels and helps prevent cardiovascular disease. It is needed for muscular growth and contraction, for the prevention of muscle cramps. It may increase the rate of bone growth and bone mineral density in children.
This important mineral is also plays an essential in blood clotting. Calcium participates in nearly every steps of the blood clotting cascade. It helps maintain normal blood pressure and prevent bone loss associated with osteoporosis as well. It also helps to prevent cancer.
Calcium provides energy and participates in the protein structuring of RNA and DNA.
It is also involved in the activation of several enzymes, including lipase, which breaks down fats for utilization by the body.

Adequate calcium intake over one’s lifetime is essential for healthy bones and teeth that will remain strong into old age. Calcium phosphate salts crystalize in a foundation material composed of the protein collagen. The resulting hydroxyapatite crystals invade the collagen and gradually lend more and more rigidity to a youngster’s maturing bones until they are able to support the weight they will have to carry.
Calcium protects the bones and teeth from lead by inhibiting absorption of this toxic metal.
