I have used L-Glutathione for years for stiffness or joint pain of any type. I works great. I am told it is the key to allow calcium and vit. D amd mag. into the osteoblasts. Without it very little gets in to keep them working properly and it works really well. It also detoxifies the liver. Also I use a product called colon tone by Dr.Eskeland. It is an oxygen based cleaner and one of the great things I noticed it also does is help with yeast infections which I have often, I am guessing the xtra oxygen in the colon kills bacteria. All I know is its great not to have to put up with those yeast infections constantly. I suppose you can find it on the web. Otherwise e-mail me and I can tell you where I get it. Also the glutathione is a very inexpensive supplement.
