5-Hydroxytryptophan (5-HTP), also known as oxitriptan, is a naturally occurring amino acid and chemical precursor as well as a metabolic intermediate in the biosynthesis of the neurotransmitter serotonin.


5-hydroxytryptophan is a tryptophan derivative that is tryptophan substituted by a hydroxy group at position 5. It has a role as a human metabolite and a neurotransmitter.


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 (5-hydroxytryptophan) is a naturally occurring substance derived from the seed pods of Griffonia simplicifolia, a West African medicinal plant. In humans, 5-HTP is the immediate nutrient precursor to the neurotransmitter serotonin (5-HT). This means that 5-HTP converts directly into serotonin in the brain. Serotonin has many profoundly important functions, including a role in sleep, appetite, memory, learning, temperature regulation, mood, sexual behavior, cardiovascular function, muscle contraction, and endocrine regulation.
