My we are now humble on this issue now. Apparently the FDA has traced the danger back to a single producer of L-tryptophan in Japan. The cause, as alot of rational folks suggested was from, contamination (or possibly an additive). I could not really understand how an essential amino acid, consumed even in "mega-doses", could cause such a drastic result. Now all I'd like to know is.... When will we see it back on the market? I will stay away from those "sale special" bottles of L-trypto..
