In one embodiment, a method for increasing circulating and/or intracellular levels of glutathione includes administering an effective amount of S-acetyl-glutathione (SAG) in the form of delayed-release composition to raise the circulating levels of glutathione to achieve clinically beneficial effects
Its defining structural feature is the gamma-glutamyl linkage: the glutamate residue is joined through its side-chain carboxyl rather than the usual alpha-peptide bond, which makes the molecule resistant to most intracellular peptidases and means it is cleaved almost exclusively by gamma-glutamyl transpeptidase at the outer cell surface (Zhang, Forman and Choi, Methods in Enzymology, 2005)
