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

5-HTP is sold over-the-counter in the United States and Canada as a dietary supplement for use as an antidepressant, appetite suppressant, and sleep aid. 5-HTP in supplement form is typically sold in 50 mg or 100 mg gelatin or vegetarian capsules. It is usually sourced from the seeds of griffonia simplicifolia.
