Evidence suggests alpha-lipoic acid may help extend the time that glutathione levels remain elevated after supplementation.L-methionine, 100mgtherapy resulted in a significant increase of hepatic glutathione levels both in patients with alcoholic and in those with non-alcoholic liver diseases as compared with placebo-treated patients.Vitamin E, 100IUglutathione level is significantly related to vitamin E level, and supplementation with vitamin E (100 IU/day) significantly increases glutathione and lowers lipid peroxidation and HbA1c concentrations in the erythrocytes of type 1 diabetic patients.Vitamin B2, 5mgis instrumental in the reduction of the oxidized form of glutathione (GSSG) to its reduced form (GSH).Selenomethionine, 200mcgstudies show that selenomethionine supplemented medium exhibited markedly elevated glutathione peroxidase activity and linear increases in abundance of GPx1 and GPx3 proteins
