Medical student here. I first learned about glutathione when I was on an obscure clinical rotation for metabolic disorders. In some of these conditions, the kids had some serious toxic metabolite buildup in their system and glutathione was shown to relieve the effects of that due to it's antioxidant activity. After reading about liposomal glutathione, I found this brand and recopmmended it as a good supplement. I think that because this supplement is liposomal it is more biologically available and resistant to degradation by stomach acid/proteases. I take this because I am a busy grad student with lots of stress and an occasional smoker so I like the idea of investing in a good, energizing antioxidant boost. It's not cheap, so I'd say consult a doctor before buying this to find out if it might relieve whatever symptoms you are having. Overall I trust this brand and their formulations, I mean it.
