GlyNAC consists of the two molecules glycine and N-acetyl-cysteine. Together, they form an effective precursor complex for glutathione - the most important antioxidant in the human body.Glutathione is found in almost all cells of our body, where it acts as a kind of guardian and firefighter together. All the biochemical processes in our cells produce free radicals, which cause damage in excess. Glutathione neutralizes these radicals by means of electrons. In addition, glutathione can regenerate other antioxidants, such as vitamins C and E. Another important task of the molecule is detoxification by making toxic substances water-soluble. Glutathione is, to put it simply, one of our most important helpers in keeping our cells healthy.
