Nature s Sunshine 5-HTP Power 60 Capsules

5-Hydroxytryptophan is a precursor to serotonin, an important neurotransmitter that helps regulate appetite, mood and sleep. 5-Hydroxytryptophan is converted into serotonin in the body, which may help elevate mood, assist in controlling hunger and promote restful sleep. 5-HTP Power blends three adaptogenic herbs-eleuthero, ashwaganda and suma-with 5-HTP to help the body adjust to changes. It also contains vitamin B6 and zinc, which support the action of 5-HTP.
