Are you taking L carnitine, Alpha Lipoic Acid and Benfotiamine? Making sure the Glutathione level is good is important. I take Lipsomal Glutathione and NAC, Alpha Lipoic acid and l carnitine for the work they do for the nerves and they also raise the level of Glutathione for the nerve healing. ALA and Benfotiamine have been amazing for my healing. Whey protein has glutathione precursers also. I put that in a smoothie every day.
