Serum magnesium levels are inversely related to the risk of death from ischemic heart disease, a researcher from the US Centers for Disease Control and Prevention. Serum magnesium concentration, independent of other risk factors, was inversely associated with death from all causes and from heart disease.

COMMENT: Magnesium is one of the most important minerals to supplement, as most of us do not get enough. If you were to juice large amounts of organic vegetables, you probably do not need any mineral supplements. However, most of the rest of us do. As you may know, magnesium is one of the best solutions for constipation. One must be careful, though, and balance some calcium with the magnesium. If one does not do this, muscle cramps are likely to result. The precise ratio is probably not too important; many advocate a 2:1 calcium/magnesium ratio. My gut feeling is that the reverse ratio of 2:1 magnesium/calcium, or equal amounts of both, would work as well. When using magnesium, it is important to avoid magnesium oxide, as this is one of the worst forms of magnesium supplementation. The best would be organically bound magnesium, which is found in organic green leafy vegetables.
