I contracted Hep C around 1984. A friend mentioned an amino acid called "Alpha-Lipoic Acid" to lower my enzymes levels AST and ALT count. He showed me in a book that had a list of elements that were taken out of our school of medicine in 1950's. I have had a level of roughly 20 AST and 35 ALT ever since. My liver doctor about 10 years ago was completly surprised by the levels, and asked what I was doing to get these levels. I mentioned "Alpha-Lipoic Acid" and he did not recognize it. It is sad when we are controlling what doctors should and shouldn't know. Hope this helps those reading.
