Magnesium plays an important role in the human body working synergistically with Calcium. Solaray Magnesium Asporotate formula consists of three different forms of Magnesium Magnesium Aspartate, Magnesium Citrate and Magnesium Orotate. Aspartic Acid, Citric Acid, and Orotic Acid have been combined for a natural chelation process. Our superior formula derives its Orotic Acid from a special delactosed whey protein concentrate. This product contains none of the yeast or soy commonly found in full range amino acid chelates.
