Admittedly my doubts are solely based on the fact that I see the 5-HTP next to the fish oil pills and other non-FDA approved supplements at the pharmacy.  It fits into the profiled of what I consider &quot;alternative medicine,&quot; and generally I agree with the idea that if alternative medicine actually worked, it would be called medicine.<p>You&#x27;ve done more research than me though.  I&#x27;ll defer to your judgment here.
