My 7-year-old has been using oral GSH (Theranatural's GSH Curc Caps) for just over 3 months now. In the beginning we didn't see much change, but then gradually she began to have better stools and began to eat better. We were thrilled. She gained weight and was eating at normal times and eating greater quantities. Unfortunately it didn't continue. She began to have loose stools again (keep in my mind we did not reduce her enzymes, but actually had to increase them, twice!). She also lost her appetite and was back to eating really bad. I don't believe the GSH caused this but I am not certain it is doing her much good either. But, since it doesn't seem to be causing any negative side-effects, we are going to continue for 3 or 4 more months to see if it has an affect in the long-term. Just wanted to share our story this far with all of you. Don't let our story deter you from using GSH. Several others have had great success. Best wishes to everyone!
