Calcium is vital for building strong bones and teeth, muscle function, release of hormones and enzymes, and assists nerves in transmitting impulses.

Magnesium is needed for making new cells, activating B vitamins, relaxing muscles, clotting blood, energy metabolism, and is concentrated in the bones and teeth. It helps keep cells electrically stable, maintains proper blood pressure, and, with calcium, regulates energy levels and maintains normal heart function and nerve transmission.

Vitamin D regulates calcium metabolism, which is important for the formation of bones and teeth.

Zinc is an essential trace mineral that is necessary for the activity of 300 or more different enzymes. Special chelates ("claws" that hold the nutrient and allow for better bioavailability) enhance the delivery and utilization of the minerals.

Regular exercise and healthy diet with enough calcium helps teen and young adult women, who are at risk of osteoporosis later in life, maintain good bone health and may reduce their risk of osteoporosis (white and Asian women are particularly at risk for osteoporosis).

Adequate Calcium intake is important, but daily intakes above 2,000 mg are not likely to provide any additional benefit.
