NOW Magnesium 400MG CAP 20s

Magnesium is a mineral necessary for energy production and metabolism, muscle contraction, nerve impulse transmission, and bone mineralization.  It is a required cofactor for around 300 enzymes.  These enzymes catalyze several reactions, including fatty acid synthesis, protein synthesis, and glucose metabolism.  Magnesium status is also important for regulating calcium balance due to its effects on the parathyroid gland.
