Thanks Bex,
It is L-Selenomethionine 200 mcg. I haven't tried it yet. How long did the bad effects last for you? I'm not exactly keen on becoming more of a nutcase than I already am at the moment lol. I'm glad it helped you detox a little though. If it weren't for the high RT3 I don't think I would even try it because of the possible anxiety side effects. Only one way to find out I guess!
