5-Hydroxytryptophan (5-HTP) is an intermediate in the natural synthesis of serotonin from the essential amino acid tryptophan. The enzyme tryptophan hydroxylase adds a hydroxyl (OH) group to tryptophan, forming the intermediate 5-HTP. In the body, 5-HTP is converted to serotonin by the removal of a carboxyl group (COOH) by another enzyme. 5-HTP is involved in the regulation of endocrine and cerebral activity responsible for emotions and sleep/wake cycles. In clinical studies, administration of 5-HTP improved REM sleep duration and promoted emotional well-being. The 5-HTP contained in this supplement is derived from a plant, Griffonia simplicifolia.
