> no, l-tryptophan is warned against with ads, especially the ssris,
Tryptophan, found as a component of dietary protein, is particularly plentiful in chocolate, oats, bananas, dried dates, milk, yogurt, cottage cheese, meat, fish, turkey, chicken, sesame, chickpeas, and peanuts.
So everyone is taking l-tryptophan with their AD's. I would question the need to take l-tryptophan as a supp at all, unless you are malnurished. It is abundant in most foods.
(no coinkidink that l-tryp was banned, then, magically prozac came to be)
>It was really a bad batch that caused EMS.
In 1989, a large outbreak of a new, disabling, and in some cases deadly autoimmune illness called eosinophilia-myalgia syndrome (EMS) was traced to L-tryptophan. The bacterial culture used to synthesize tryptophan by a major Japanese manufacturer, Showa Denko KK, had recently been genetically engineered to increase tryptophan production; with the higher tryptophan concentration in the culture medium, the purification process had also been streamlined to reduce costs, and a purification step that used charcoal absorption to remove impurities had been omitted. This allowed another bacterial metabolite through the purification, resulting in the presence of an end-product contaminant responsible for the toxic effects. The FDA was unable to establish with certainty that this was the sole cause of the outbreak. Tryptophan was banned from sale in the US, and other countries followed suit.
