what is a zma
ZMA is a combination of two essential dietary minerals (zinc and maganesium) and vitamin B6. Zinc and magnesium are sometimes not adequately supplied in the diet, while vitamin B6 generally is. The zinc is in the chemical forms zinc methionine and aspartate; the magnesium is in the aspartate form. There is no scientific evidence for any claim that ZMA has any effects beyond those of taking equivalent amounts of zinc, magnesium and vitamin B6 in any other form. All of these substances are healthy and thus the combination will also be healthy so long as it is not overdosed.
ZMA is a synergistic blend of two minerals, zinc and magnesium, and a vitamin, Vitamin B-6 or pyridoxine. All three of these compounds are extremely important in biological processes, and USDA studies have shown that less than 70% of Americans get enough zinc, and less than 40% get enough magnesium.
