Solaray Magnesium Citrate 90 Vegetable Gel-Caps is a food supplement based on magnesium, a mineral indispensable to the body.<br /><br />Magnesium is a mineral essential to all biochemical processes of the body, and deficiencies are frequent. The minerals contained in this product were chelated with full rice concentrate rather than milk, yeast or soy protein, which are generally used to chelate minerals. The special rice concentrate used by Solaray is about seven times richer in amino acids than ordinary rice.
