how much magnesium daily
The Recommended Daily Allowance (RDA) of magnesium for young adults is around 400 mg/day for men and 310 mg/day for women. For adults over 30, the RDA is 420 mg/day for men and 320 mg/day for women. However, despite how easy it is to find magnesium, studies have shown that between 68% and 75% of American adults are magnesium deficient.
In the United States, however, the average daily magnesium intake is about 320 mg for men and about 230 mg for women, or 24% and 28%, respectively, below the RDAs. A recent study showed that elderly American men and women consume only about 225 and 166 mg/day of magnesium, respectively, or 46% and 48% below the RDAs.or adults aged 31 or older, the Food and Nutrition Board of the Institute of Medicine has set the Recommended Dietary Allowance (RDA) for magnesium at 420 mg/day for men and 320 mg/day for women (for adults aged 19â30, the figures are 400 and 310, respectively).
