Magnesium and Zinc Supplementation May Improve Bone Density

Magnesium and zinc also improve bone density. Although most of the media attention focuses on calcium, it actually plays a relatively small role in bone density (see Osteoporosis Overview ) This recent study explores the role of magnesium and zinc in having strong bones.

In this study involving postmenopausal women with osteoporosis (n=40), osteopenia (n=40), or normal bone mineral density (n=40), results indicate significantly lower serum magnesium and zinc status in osteoporotic women, compared to osteopenic and normal women. Serum concentrations of magnesium, zinc and copper were measured in the participants. Mean concentrations of magnesium and zinc were significantly lower in osteoporotic women than in both osteopenic and normal women. Additionally, mean concentrations of magnesium and zinc were significantly lower in osteopenic women than in normal women. However, no significant differences in mean concentrations of serum copper were observed between the three groups. Thus, the authors of this study conclude, "The clinical significance of these changes needs further elucidation, but trace element supplementation, especially with magnesium and zinc and perhaps copper, may have beneficial effects on bone density."
