5-HTP

5-HTP is a naturally-occurring bodily synthetic compound creating the mood-regulating hormone, serotonin. The compound is also produced naturally in numerous types of plants. This is includes a West African shrub, griffonia simplicifolia, producing 5-HTP in the seeds. 5-HTP works in the brain and central nervous system by expanding the production of the chemical serotonin (one of the things responsible for sleep, appetite, temperature, feeling pain, and sexual stimulation functions).
