5-HTP (5-hydroxytryptophan) is a naturally-occurring metabolite of the essential amino acid tryptophan. 5-HTP for use in dietary supplements is derived from the seeds of the Griffonia simplicifolia plant. Metabolism and absorption of 5-HTP 5-HTP (5-hydroxytryptophan) is formed by the addition of a hydroxyl group (-OH) to the 5 carbon of the indole ring of tryptophan. Conversion of tryptophan to 5-hydroxytryptophan is catalyzed by the enzyme tryptophan hydroxylase. 5-HTP functions as the precursor for serotonin, and is converted to serotonin in a pyridoxal phosphate (vitamin B6) dependent reaction catalyzed by the enzyme L-amino acid decarboxylase. Synthesis of serotonin in the brain requires an adequate supply of either tryptophan or 5-HTP as precursors. The supply of tryptophan available for conversion to 5-HTP depends on a number of factors, including nutritional status and competition between tryptophan and other amino acids for transport across the blood brain barrier. Brighten your mood and promotes sound, restful sleep. Helps the body produce serotonin the neurotransmitter which regulates sleep and emotions.
