Supports antioxidant activity Altrient Glutathione helps to regenerate important antioxidant nutrients and is the perfect complement to a well-balanced antioxidant rich diet

However, cultured rat astrocytes can also synthesize the glutamate needed for GSH synthesis from ketoglutarate, glutamine, or proline and can generate glycine from serine (Dringen and Hamprecht 1996, 1998)

Until these studies are expanded to include simultaneous S and N-Balance determinations and biosynthetic studies in animals, and well controlled S-balance studies in humans are performed we will not be able to clearly answer this important question
