NAC FOR ANTIOXIDANT SUPPORT
NAC (n-acetylcysteine) is a form of the amino acid cysteine, which is more readily taken up by the cells. It is a precursor in the body to the cellular antioxidant glutathione (GSH), which is produced intracellulary, particularly in the liver. Cells cannot absorb preformed GSH, making preformed glutathione supplements of minimal effectiveness. Intracellular levels of reduced glutathione are best maintained with R(+)-lipoic acid, the natural form of this key antioxidant.
