Formulation Notes

Magnesium is a mineral that is critical for energy production and metabolism, muscle contraction, nerve impulse transmission, and bone mineralization. It is a required cofactor for an estimated 300 enzymes. Among the reactions catalyzed by these enzymes are fatty acid synthesis, protein synthesis, and glucose metabolism. Magnesium status is also important for regulation of calcium balance through its effects on the parathyroid gland. Magnesium Citrate is easily absorbed, and NOW Magnesium Citrate Softgels are provided in a liquid base with chelated forms for superior bioavailability.

Natural color variation and oil separation may occur in this product.
