Throughout life‚ cells known as osteoblasts construct bone matrix and fill it with calcium. At the same time‚ osteoclasts work just as busily to tear down and resorb bone. This fine balance is regulated by many factors‚ including systemic hormones and cytokines. Bone mass reaches its peak by the middle of the third decade of life and plateaus for about ten years‚ during which time bone turnover is constant‚ with bone formation approximately equaling bone resorption.
As our bodies age‚ this fine balance is lost. As the relative hormone levels shift in midlife — more drastically in women than in men — the osteoclasts gain the upper hand and bone mass begins to dwindle. Some bone is already being lost by the time women reach menopause‚ but the rate of loss can increase up to tenfold during the first five years after menopause.
Bone density loss is not just associated with calcium deficiency‚ but also with an insufficient intake of a host of other nutrients including magnesium and vitamin D3. In order for calcium to help maintain healthy bones‚ adequate amounts of vitamin D3‚ zinc‚ magnesium‚ manganese‚ and other nutrients should be available so that calcium and phosphorus can be incorporated into the bone matrix. Additionally‚ many forms of calcium are not particularly well absorbed.
While loss of bone mineral density is more commonly experienced by women‚ aging men can also have this issue. Both men and women may experience significant deficits of magnesium if they do not supplement. Bone Restore now contains 300 mg of magnesium. Magnesium is not only needed to maintain strong bones‚ but it is critical to promoting a healthy vascular system. In fact‚ magnesium is critical for facilitating hundreds of enzymatic reactions that our bodies require to maintain optimal health.
