I am beginning a new regimen of melatonin. Should I take 5-HTP along with melatonin to assure sleep?
A shopper on Dec 22, 2011
BEST ANSWER: You didn't state how much melatonin you are taking. Since Jarrow Formulas 5-HTP promotes the creation of melatonin by the body you don't want to take excessive amounts along with 5-HTP.
