Magnesium Bisglycinate utilizes Magnesium bound to the amino acid Glycine, which facilitates intestinal absorption. Magnesium is a mineral that activates an estimated 300 enzymes, including those that regulate functions critical for energy production and metabolism, muscle contraction, nerve impulse transmission, and bone mineralization. In addition, Magnesium is required for fatty acids synthesis, protein synthesis, and glucose metabolism. Magnesium status is also important for regulation of Calcium balance through it effects on the parathyroid gland.
