5-HTP 100 mg 60 vegcaps promotes an increase in brain serotonin levels to support mental wellness, appetite control, and balanced sleep patterns*. 5-Hydroxytryptophan is a precursor in the body's natural process of synthesizing tryptophan to serotonin. This enzyme-catalyzed reaction requires the addition of a hydroxyl group (OH) to the amino acid tryptophan to form 5-HTP, then a second enzyme removes a carboxyl group (COOH), producing serotonin. Serotonin supports the regulation of endocrine and neurological activity, responsible for mood, satiety, and sleep/wake cycles. Clinical studies indicate that 5-HTP supports serotonin production. These vegcaps contain 5-HTP sourced from Griffonia simplicifolia plants*.
