Be the first to review this product

Natural Factors: Calcium & Magnesium plus Potassium & Zinc (90 Tablets) is for the normal development and maintenance of bones and teeth.
Calcium is required for strong bones, teeth and cardiac function. Calcium not only builds strong bones and teeth but maintains bone density and strength. It helps to regulate heartbeat, blood clotting and muscle contraction. 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. That's why magnesium is so important to bone formation, nerve and muscle transmission, and energy production.

The other minerals, including manganese, potassium and zinc, are also in the citrate form for better absorption and utilization by the cells, and they provide a valuable contribution to bone strength. The chelated form is better tolerated by those with allergies to citric products for the calcium and magnesium.


1-2 tablets daily with meals, a few hours before or after taking other medications or as directed by a health care practitioner. For adult use only. Keep out of the reach of children.
