5-HTP 5 HTP (5-Hydroxytryptophan) is a compound produced in the body from the amino acid tryptophan. It is a precursor to the neurotransmitter serotonin and the hormone melatonin. 5-HTP is manufactured from the seeds of an African plant, Griffonia simplicifolia. The supplements have become popular because it is thought that providing the body with 5-HTP in pill form can boost the body’s serotonin levels, similar to the antidepressants that are thought to increase the amount of serotonin available to the brain.
5-hydroxytryptophan (5-HTP) is a chemical that the body makes from tryptophan (an essential amino acid that you get from food). After tryptophan is converted into 5-HTP, the chemical is changed into another chemical called serotonin (a neurotransmitter that relays signals between brain cells). 5-HTP dietary supplements help raise serotonin levels in the brain. Since serotonin helps regulate mood and behavior, 5-HTP may have a positive effect on sleep, mood, anxiety, appetite, and pain sensation.
