Magnesium is a mineral used by every organ in the body. By some estimates, up to 80% of Americans are not getting enough of this key mineral. Magnesium insufficiency has been implicated in a wide variety of health challenges. The importance of bioavailability is obvious. Signs of inferior mineral supplements include the use of cheap, poorly absorbed rock-salt minerals like calcium carbonate and magnesium oxide which can cause digestive distress. Magnesium Chelate-HP provides highly concentrated forms of chelated magnesium for optimal absorption and GI comfort.
