Reverse T3 was tested as well and came up within normal ranges.
I'm taking a little bit of vitamin C and E in a multivitamin. In the past I have taken Vitamin C up to 7 grams a day for a month or so at a time and whatever the max safe dose of Vitamin E is.
Right now I have some reduced glutathione I'm getting ready to try for a while before retesting the GSH levels. Vitamin C and E will definitely be on my list of things to try if the reduced glutathione fails. I've been reviewing my whey protein isolate and find that it probably isn't of a kind to correct my GSH, might have to look into some bioactive whey at some point as well if there are problems raising those test levels.
