I have been using GSH orally for about 4 years now. It has helped a LOT. I get mine from www.Iherb.com
You can learn about GSH and what it does by going to these links..........

I myself have never bothered with NAC, because NAC does help the body to produce glutathione but it can be toxic if you take too much. Taking Glutathione ( GSH) itself seemed the most logical recourse to me since thats exactly what the body needs. It isnt toxic, and I figured why go the long way to get it, when i can just take it directly?
although like Jody, i always keep an open mind. Since all of these are still in the experimental stages who really knows which is truely better? What works for one may not work for the other.
