Natural Factors uses carbonate as the calcium source and it is better tolerated by individuals who are allergic to citrus products. Calcium is vital to our body for the maintenance of healthy bone density and strength. It regulates heartbeat, prevents blood clotting and helps with muscle contraction. Magnesium, an important mineral needed for Calcium absorption, plays a key role in nerve and muscle transmission as well as energy production. Natural Factors also included Vitamin D in this formula to enhance the absorption of Calcium. Daily intake of Natural Factors 2:1 Calcium & Magnesium will give your strong and healthy bone.
