From the 1996 FDA Science Forum. Abstract.
Since magnesium (Mg), an essential nutrient, is abundant in the environment and food supply, it is generally assumed that Mg deficiency is not a problem. However, the literature indicates that deficiencies may exist in both thirdworld and industrialized nations and may influence cardiac and vascular diseases, diabetes, bone deterioration, renal failure, hypothyroidism, and stress. Because Mg in certain forms is not easily absorbed and no classical symptoms exist, the problem of Mg deficiency is readily masked, especially in high risk groups such as diabetics, alcoholics, those taking hypertension medication, and some athletes. The current Recommended Daily Allowance (RDA) for the US is 6 mg/Kg/day, which translates to 420 mg for a 70 Kg man. The estimated intake in the US is 300 mg/day. Studies show that as much as 3 times this amount may be needed by the general population and especially by those predisposed to cardiac disease states. This report summarizes recent research on Mg in human diets and the results of Mg deficiencies.
