Magnesium is a mineral that is critical for energy production and metabolism, muscle contraction, nerve impulse transmission, and bone mineralization. &ampnbsp;It is a required cofactor for an estimated 300 enzymes. &ampnbsp;Among the reactions catalyzed by these enzymes are fatty acid synthesis, protein synthesis, and glucose metabolism. &ampnbsp;Magnesium status is also important for regulation of calcium balance through its effects on the parathyroid gland.*
