Bone is a living mineral structure, much more than a mere collection of dormant mineral salt crystals. Because it's living tissue, bone has diverse nutritional needs. Calcium serves numerous function in human metabolism. Calcium phosphate comprises about 85% of the mineral component in bones and teeth. Bone serves a myriad of functions beyond providing shape and support for the body. Bone tissues serve as storage sites for mineral salts and blood cells are formed in its marrow. In Nature, certain nutrients and extracts show remarkable abilities to support cellular health, increase bone density and maintain the bones in good state of repair to support healthy bone function.
