5-HTP (5-hydroxytryptophan) is a naturally-occurring amino acid. Bulk product is usually extracted from Griffonia Simplicifolia Seed. Though 5-HTP is found in food only in insignificant quantities, it is an intermediate in the metabolism of tryptophan, an amino acid found in turkey, milk, potatoes, pumpkin, and various greens. 5-HTP is a precursor of neurotransmitter serotonin. Serotonin is a neurotransmitter which is responsible for mood, hunger and sleep. 5-HTP works through increasing the amount of serotonin produced in central nervous system tissue. Many researches show that 5-HTP may support suppressing appetite, weight loss[1-3], anti-depression, good mood conditions, sleep aid, and cognitive enhancement.

On the other hand, because 5-HTP has not been thoroughly studied in a clinical setting, possible side effects and interactions with other drugs are not well known.

[1]. Eating behavior and adherence to dietary prescriptions in obese adult subjects treated with 5-hydroxytryptophan.Cangiano C, Ceci F, Cascino A, Del Ben M, Laviano A, Muscaritoli M, Antonucci F, Rossi-Fanelli F. 3rd Department of Internal Medicine, University of Rome, La Sapienza, Italy. Am J Clin Nutr. 1992 Nov;56(5):863-7. Previous observations have shown that oral administration of 5-hydroxytryptophan (5-HTP) without dietary prescriptions causes anorexia, decreased food intake, and weight loss in obese subjects. To confirm these data over a longer period of observation and to verify whether adherence to dietary restriction could be improved by 5-HTP, 20 obese patients were randomly assigned to receive either 5-HTP (900 mg/d) or a placebo. The study was double-blinded and was for two consecutive 6-wk periods. No diet was prescribed during the first period, a 5040-kJ/d diet was recommended for the second. Significant weight loss was observed in 5-HTP-treated patients during both periods. A reduction in carbohydrate intake and a consistent presence of early satiety were also found. These findings together with the good tolerance observed suggest that 5-HTP may be safely used to treat obesity.
