Magnesium eases depression

Magnesium plays a role in energy metabolism in the brain. In the first phase of this study, doctors measured magnesium levels in people with depression. In the second phase, doctors evaluated participants who were deficient in magnesium—below 1.8 mg per deciliter of blood in men and below 1.9 mg in women—and who had a score representing at least minor depression on the standard Beck Depression Inventory questionnaire. The 60 people who continued in the study took two 250 mg tablets of magnesium oxide per day, or a placebo. After two months, those taking magnesium saw a 50 percent greater improvement in depression scores. By the end of the study, about 90 percent of those in the magnesium group had returned to normal circulating levels of magnesium, compared to about half of those in the placebo group.
