5-HTP, the intermediate metabolite between the amino acid L-tryptophan and serotonin, is extracted from the seed of an African plant (Griffonia simplicifolia). This dietary supplement is typically used as a sleep supplement and supports a positive mood and relaxation. 5-HTP supports the production of serotonin in the brain and central nervous system; serotonin can impact sleep, mood, appetite, and body temperature.
