Calcium is the mineral most likely to be deficient in the average diet. It is the chief supportive element in bones and teeth. Calcium salts make up about 70 percent of bone weight and give your bones its strength and rigidity.

About 99 percent of the calcium in the human body is held in the bones and teeth. The remaining one percent of calcium circulates in the bloodstream, where it performs a variety of important functions:

  • It helps to contract muscles and helps regulate the contractions of the heart.
  • It plays a role in the transmission of nerve impulses and in blood clotting.
  • It is involved in the stimulation of contractions of the uterus during childbirth and in milk production.
  • It also regulates the secretion of various hormones and aids in the functioning of various enzymes within the body.
  • These regulatory mechanisms help prevent a deficiency in calcium from developing in the bloodstream.

This mineral is a major contributing factor to the prevention of bone density loss and osteoporosis (disease characterized by low bone mass and deterioration of bone tissue).
