MAGNESIUM is an essential mineral nutrient. This vital mineral is needed by over 300 of the body's enzymes. It plays an important role in bone formation, stress, mood, PMS and chronic fatigue. Trophic, by pre-chelating Magnesium with amino acids, relieves the body of trying so hard to absorb the mineral. Trophic's patented Albion Magnesium, chelated with natural amino acids, provides superior biological activity or bioavailability and absorption.
