Did the stuff you read about glutathione say anything about taking n-acetyl cysteine as well? I've read stuff that says that NAC is a precursor of glutathione and if you want to boost your glutathione levels, this is the best way. Taking glutathione directly doesn't do anything apparently, unless you inject it intravenously, which they say is very expensive. Where did you do your liver detox profile? Did you send away to Great Smokies Labs or something like that or have a doctor do it?
