The tolerable upper intake limit is set at 350 mg for adults.

Magnesium requirements are increased during rapid growth in children and adolescents. The RDA for adolescent boys is 410 mg and for girls is 360 mg.

Magnesium recommended dailyStudies have shown that most people may not get sufficient magnesium in their daily diets. Some research indicates that the RDAs for magnesium may be inadequate and that those who exercise may need up to 500 mg per day. Dr. Mildred Seelig, a well-known magnesium researcher, has recommended a daily intake of 6 to 10 mg per kg of body weight per day for optimal health.

Less than 1 per cent of the total body magnesium is present in blood. Thus, blood serum measurements of magnesium that are routinely made in a clinical setting assess only a small part of the total magnesium stores in the body and magnesium in the blood does not necessarily correlate with the amount

of magnesium in other parts of the body. More sophisticated tests are not readily available in a clinical setting and even for these tests, results do not necessarily correlate with intracellular magnesium. Thus, there is no readily available test to determine intracellular/total body magnesium status. At present there is little information about the state of magnesium within body pools and deficiencies are difficult to pinpoint.
