I heard someone talking (Maybe Dr.Oz?) about taking 5htp and green tea as a successful aid in weightloss. I am anti-diet pills, but 5htp seems to have other great uses (sleep aid, mood lifter, etc.) BUT I don't know much about the side effects, and I am wary of that. (I have mitral valve prolapse so am cautious.) Anyone take this or this combo? Was it useful? Or is it just a fad?
