5-Hydroxytryptophan—commonly known as 5-HTP—is a compound made naturally in the body. 5-HTP helps the body to produce more serotonin.
Serotonin is a neurotransmitter that plays a key role in regulating mood and sleep-wake cycles. Healthy levels of serotonin contribute to a positive mood and outlook and also promote restful sleep. Serotonin also plays an important role in many other of the body’s functions, including digestion, appetite reduction, and pain perception.
