Magnesium plays an important role in the human body working synergistically with calcium. Solaray® Magnesium Asporotate™ 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. This 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.
