A study published in the Journal of the American Geriatric Society has shown that dietary intake of magnesium is associated with an increase in bone mineral density in older men and women.
The study included 2,038 men and women aged 70-79 that were enrolled in the Health, Aging and Body Composition Study. Food frequency questionnaires were used to assess magnesium intakes and document any medications. The data also accounted for variations in age, body mass index (BMI), smoking status, alcohol use, physical activity, estrogen use, and supplemental calcium and vitamin D.
Higher magnesium intake through diet and supplements was positively associated with total - body bone mineral density (BMD) in older white men and women. For every 100 mg per day increase in magnesium, there was an approximate 2 per cent increase in whole-body BMD.
The results have important implications since osteoporosis currently affects over 10 million adults in the U.S. alone, with another 34 million suspected to have low bone mass. In addition, earlier dietary surveys have consistently shown that a large portion of adults do not meet the RDA for magnesium.

We often hear of the benefits for women of daily calcium supplements in the prevention of osteoporosis. In fact, many women make it a point to take a daily calcium supplement for this very reason. This piece of research is an important example of how minerals outside of calcium can benefit both women AND men.
When choosing a mineral supplement, it's especially important to note how the supplement is produced. It is commonly known that "chelated" minerals are most readily absorbed by the body.

Many consumers of nutritional supplements do not realize that there is an impending danger to their Right to take nutritional supplements. Codex Alimentarius, or 'Codex' for short, a part of the Central American Free Trade Agreement, CAFTA, could result in an international body, the World Trade Center (WTC), restricting or banning the personal use of nutritional supplements under the ‘harmonization’ of international standards. Supplement use is severely restricted in many European countries. To prevent this from happening here, consider supporting Dr. Ron Paul in his quest for the presidency of the United States. Ron Paul understands that individuals have rights and, as a Congressman, has introduced legislation to protect people's right to take nutritional supplements.
