Calcium is required for strong bones, teeth and cardiac function. Calcium citrate may be the preferred form of calcium for those with low stomach acid.

Studies show that mineral citrates have superior absorption, even when taken on an empty stomach. Each capsule has calcium and magnesium in a one-to-one ratio that many health professionals now recommend.

As well as protecting the body from stress, magnesium works with calcium to provide help to these same body systems and participates in more than 50 different biochemical reactions.

The other minerals, including manganese, potassium and zinc, are also in the citrate form for better absorption and utilization by cells in the body, and all provide a valuable contribution to bone strength.

Vitamin D is included because it acts as a hormone that allows the body to absorb and properly use calcium.
