It is a combination of calcium, magnesium and vitamin D3. Calcium is important for healthy bones and teeth; it helps muscles relax and contract; important in nerve functioning, blood clotting, blood pressure regulation, and immune system health.Magnesium commonly found in bones is needed for making proteins, to aid in muscle contraction, transmission of nerve impulses as well as maintaining immune system health.Vitamin D3 increases the absorption of calcium in the body from your diet which is necessary for strong bones. Without sufficient vitamin D, bones can become thin and brittle which might put one at risk of fractures.

Calcium and vitamin D help to reduce the loss of bone mineral in women who have reached menopause. Low bone mineral density is a risk factor for bone fractures.
