5-HTP (5-Hydroxytryptophan) is an amino acid that is naturally produced in the body. It is a precursor to the neurotransmitter serotonin (the happy chemical) and the hormone melatonin. It is harvested from the seeds of an African plant, Griffonia simplicifolia. This nootropic can help with lowering depression, aid in weight loss and promote sleep by increasing melatonin production.
