Toxic L-tryptophan: Shedding Light on a Mysterious Epidemic
by William E. Crist
|
Preface by Jeffrey Smith
In chapter 4 of my book Seeds of Deception, I present the story of a deadly epidemic in 1989 that was linked to an L-tryptophan food supplement produced by genetically engineered bacterium. Much of the material was based on the research of William Crist, whose work is reproduced here.
I want to acknowledge William for his years of work, which has uncovered important information about this tragic event.
The material is presented in sequence.
