Minerals for LifeTM provides the wide range of elements ("minerals") proven essential to human life functions. Its constituents and cofactors support the diverse metabolic pathways that facilitate life, from the survival level up through the most sophisticated organ functions. They activate enzymes which control thousands of metabolic pathways operating simultaneously in all the 100 trillion cells of the living body. They are essential to cell membranes, the dynamic action centers of the living cell. These essential elements become depleted from the body by stress (emotional or chemical), poor diet, negative lifestyle factors, and surgical operations or other tissue trauma. EDTA chelation therapy also can contribute to loss of essential elements. The sources used have been exhaustively researched to ensure highest bioavailability.
