Abstract:
Disclosed are two novel crystalline forms of S-acetyl glutathione (SAG) called Form A and Form B, obtained by crystallization of SAG from mixtures of water-acetone, water-ethanol or water acetone under controlled conditions. Forms A and B can be advantageously used as ingredients of pharmaceutical or nutraceutical formulations.
