Magnesium is an essential mineral for health, strength, and longevity; it functions as the required bio-inorganic catalyst in over 350 enzyme reactions. Magnesium is necessary for energy (ATP) production; sustaining heart health and healthy blood vessels; maintaining adequate blood flow to the brain to support healthy neurons and nerves; and for optimal skeletal muscle function. Mag Complete is a blend of four bioavailable forms of magnesium, designed to provide optimal absorption and utilization of magnesium.
