5-HTP acts as an intermediate metabolite between the L-Tryptophan amino acid (tryptophan) and the neurotransmitter Serotonin (serotonin). Tryptophan is converted to 5-HTP, which in turn converts to serotonin. Serotonin plays an important role in many organic functions such as appetite control, mood stability and sleep.
