Now 5-htp

Posted by Reviewer2973134 on Nov 14, 2007

It is ok for the price, but I don't think it is quite as effective as another brand that I have used, and will go back to.

Consider St John's

Posted by Reviewer3197343 on May 23, 2008

I prefer St John's Wort to 5-HTP. However, the quality of the 5-HTP was good and as always iHerb comes through for me.
