Magnesium Linked to Bone Health
A new study shows magnesium plays a key role in bone fracture risk in older adults. Research suggests adequate blood levels of this essential mineral—along with calcium and vitamin D—can help reduce the risk for fractures associated with bone loss and osteoporosis.
Results of the study, which were published in the European Journal of Epidemiology, indicate low blood levels of magnesium increase the risk of bone fractures and high blood levels decrease the risk. The study involved 2,245 middle-aged men. Over the course of the study—20 years—participants with low blood levels of magnesium had a significantly higher risk of bone fractures—especially fractures of the hip. High levels of magnesium were associated with a 44 percent lower risk of fracture, and very high levels prevented fractures altogether in the study.
However, research does not show a correlation between dietary intake of magnesium—which is found in leafy green vegetables, legumes, nuts, seeds, whole grains, and fortified foods, according to the National Institutes of Health—and bone health. Digestive disorders, as well as some medications, can interfere with the absorption of magnesium from food and supplements may be necessary.
