Government guidelines suggest 420 milligrams (mg) per day for men, 320 mg for women. We recommend that both men and women aim to get 400-500 mg of magnesium per day. It may be tough to get all the magnesium you need from food, so top up your daily intake with a multivitamin that contains at least 100 mg of magnesium.

Current magnesium intakes in the US population are below recommended levels (400-420 mg/day for men and 310-320 mg/day for women). Dietary sources rich in magnesium include green leafy vegetables, unrefined grains, legumes, beans, and nuts.

This is a question that comes up often. A lot of people wonder how much magnesium is too much magnesium. Magnesium toxicity is a concern for some. I felt it was time to explore the symptoms of a magnesium overdose. Personally, I take 500 mg of magnesium a day. I have been using JigSaw Magnesium w/SRT for a while and have been pretty happy with the results.

The Linus Pauling Institute supports the latest RDA for magnesium intake (400-420 mg/day for men and 310-320 mg/day for women). Following the Linus Pauling Institute recommendation to take a daily multivitamin/mineral supplement may ensure an intake of at least 100 mg of magnesium/day. Few multivitamin/mineral supplements contain more than 100 mg of magnesium due to its bulk.

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.

The adult human body contains about 25 grams of magnesium. Over 60% of all the magnesium in the body is found in the skeleton, about 27% is found in muscle, 6% to 7% is found in other cells, and less than 1% is found outside of cells (1).

One study in adolescent boys found that magnesium absorption was lower when protein intake was less than 30 grams/day, and higher protein intakes (93 grams/day vs. 43 grams/day) were associated with improved magnesium absorption in adolescents (5).

This makes it always important to check the labels of these supplements carefully before consuming them. A good oral magnesium supplement will provide between 150 mg and 400 mg of magnesium per dose. Oral magnesium supplements are available in tablet, capsule or chewable tablets for children. Magnesium supplements are best taken with a meal so that they are more readily absorbed into the body.

It is my opinion that without blatant disregard for recommended daily magnesium dosage you should not see any side effects of too much magnesium. As I mentioned earlier, I take 500 mg of magnesium daily in supplement form. This is on top the magnesium I receive from magnesium rich foods. I do not plan on taking any more than 500 mg in a day. This is not a “more is better” situation.
