More Info 5-hydroxytryptophan (5-HTP) is obtained from the seeds of the African shrub Griffonia simplicifolia. In the body, 5-HTP has a variety of ways it may support healthy brain function.* 5-HTP is converted in the body to serotonin, which can affect sleep, appetite, temperature, sexual behavior, pain sensation, and mental states.* Serotonin is further converted into melatonin, the well-known sleep hormone.* Vitamin B6 is required for amino acid, carbohydrate, and lipid metabolism.* It is required for numerous metabolic transactions in the body, including the conversion of 5-HTP to serotonin.* The typical form of B6 in supplements is pyridoxine, which requires further transformation to have its full effect. The coenzyme form of B6, pyridoxal-5-phosphate, is the active form of pyridoxine, and supports metabolic needs for a wider range of individuals.*
