one tissue contains approximately 60% of the magnesium found in the body. One of the properties of magnesium within the skeletal structure is to help regulate calcium within the bones and teeth. For example, magnesium is needed in order for calcium to be bound to tooth enamel. In addition to an influence on the hormonal processes involved in bone calcium metabolism, magnesium may increase the activity of vitamin D (which, among other things, aids calcium absorption). Although calcium is the most abundant skeletal mineral and the best-known nutrient for maintaining bone density, in recent years the focus on the role of magnesium in bone health has increased considerably. In fact, many experts now feel that magnesium intake is at least as critical to skeletal health as calcium. Research indicates that osteoporotic women have less bone magnesium and that magnesium intake is a significant statistical predictor of bone mineral content.
