I read a short story about the tryptophan banning in a nutrition book.
Basically, the story is that a Japanese manufacturer of tryptophan sold 'bad'
quantities of it..'bad' because they were infected with a microbiological
organism (I forget the name) and caused several deaths.  As far as I know,
tryptophan is by itself, harmless within some range (and good for sleep
quality);  Its naturally high in milk and banannas (sp.? :>).  Of course my
info is from reading the book.
