I have heard that L Tryptophan could be used for several conditions, including anxiety and depression. Still, I have also heard that it is not favorable in U.S. even though it can be acquired by internet. Why is that? I guess that I am thinking of using this product because it looks to me that it is more natural then the other substances that affect the brain in the therapy. What do you think?
L- tryptophan is sold as a dietary product. Beside anxiety and depression, it is said that it can deal with the problems regarding sleep problems, PMS, problems with quitting smoking etc. The problem with it was certain number of fatal cases, all of them used L tryptophan. This happened in 1989. and it was determined that there were impure ingredients in the L tryptophane produced by some company from Japan. After that no similar cases were found, but still the doubt remains.
