5-HTP is the intermediate precursor in the natural synthesis of serotonin, a neurotransmitter that helps to regulate mood, appetite, and sleep/wake cycles. 5-HTP readily crosses the blood-brain barrier and clinical studies suggest that 5-HTP can support healthy serotonin levels. Serotonin is associated with positive mood and provides a substrate for the production of melatonin. This formula includes B-Vitamins as cofactors, and is further enhanced with Glycine, Taurine, and Inositol.
