Magnesium is a mineral that is essential for a wide range of fundamental cellular functions as it is a cofactor in at least 300 different enzymatic reactions. Magnesium is well known for its roles in healthy cardiovascular function and bone formation and mineralization. It is also critical for the regulation of muscle contraction and nerve conductivity through its influence on cell membrane permeability, as well as on the maintenance of the proper charge balance of the bodily fluids. In addition, Magnesium is essential for the production of cellular energy from the metabolism of carbohydrate and fat. These softgels combine Magnesium Citrate with Magnesium Glycinate for superior bioavailability.
