5-HTP, or 5-hydroxytryptophan, is a precursor to serotonin—a neurotransmitter which is essential for controlling mood, sleep and pain levels. 5-HTP may help promote serotonin production in the brain, which may support healthy mood. For best results and quickest absorption, take 5-HTP supplements on an empty stomach. Do not take 5-HTP for more than three consecutive months without consulting a healthcare practitioner.
