Title: Hard to rate supplements or their providers.
Review: I read recently where Amazon does not timely pay their outside providers. These are businessed who chose to market their products thru Amazon because of the large market. They have to sign an Amazon favored contract. Amazon has an ambiguous method of decieding how good the vendors are, and sometimes withholds payments. Thus is not good for a small business.This product and its supplier are very good; with low prices and timely delivery. 5-HTP has Tryptophan, an aid to rest and sleep. I have taken it with other medications for insomnia and other sleep problems. It is effective insofar as any supplement is effective. There are no side-effects.
