In GNC they had something on sale for about $17.00. It was L-Tryptophan. When I looked in the back for the ingredients it said: "L-Tryptophan L-ONE***" or something like that. Other ingredients included Magnesium, Glucose, etc. Would this be good enough to use as my L-Tryptophan or would you recommend a different company? Thanks.
