According to my biological dentist's instructions, I took glutathione, along with a bunch of other stuff, for the first six months after replacement (and for two weeks before). The other two weird-sounding ones were N-Acetyl Cysteine and Methionine. And I took a lot of vitamins which I am still taking- mostly the usual ones. Lately, I have added taurine and extra selenium and zinc. I did quite alright when taking the glutathione. Had some good days and some bad ones, but nothing I couldn't handle. I also have an easy time with sulpher, as far as I can tell.
