Cal/Mag 2001 tablets from Douglas Laboratories® provide 750 mg of elemental calcium from a calcium complex, together with significant amounts of magnesium from an aspartate/ascorbate complex, as well as vitamin D-3. Other nutrients are also included to assist the body in maintaining healthy bone structure.
The adult human body contains approximately 1,200 g of calcium, about 99% of which is present in the skeleton, and 20-30 g of magnesium with about 60% located in bone. Bone is constantly turning over, a continuous process of formation and resorption. In children and adolescents, the rate of formation of bone mineral predominates over the rate of resorption. In later life, resorption predominates over formation. Therefore, in normal aging, there is a gradual loss of bone.
