5-HTP may have a positive effect on sleep, mood, anxiety, appetite, and pain sensation. When taken with gamma aminobutyric acid (GABA), 5-HTP might help people fall asleep faster, decrease sleep latency, increase duration of sleep, and improve the quality of sleep.
5-HTP can be produced as a supplement from the seeds of an African plan called Griffonia simplicifolia.
Tryptophan, an essential amino acid obtained through food, is converted by the body to 5-HTP via the enzyme tryptophan hydroxylase. 5-HTP is then converted into serotonin, a prominent central nervous system neurotransmitter that regulates mood and behavior.
