Ed,
Why the rigorous controls and follow up, in the UK?
As I post lower down the thread, I've been prescribed a pharmaceutical grade Tryptophan by my Pdoc, here in Canada. It's manufactured by Apo. But we have no such strict follow-ups.The original N.American ban on OTC Trypt. was due to ONE bad batch of pills, manufactured in Japan, with a contaminated filler. (One, or more people died, several became ill). This was in the early 1990's I believe. The L-Tryptophan itself was later found to be safe, and the ban was lifted.
Taking a health food store product can be a risk, in terms of purity or quality.All the best,
Jas
