5-HTP comes from the beans of Griffonia Seed, a vine native to Africa. In African folk medicine, Griffonia Seed is reputed to be an aphrodisiac, as well as an antibiotic and a remedy for diarrhea, vomiting, and stomachache. Recent research suggests that Griffonia Seed raises serotonin levels in the brain. Serotonin is important in regulating brain chemistry and is especially important in problems such as depression, insomnia, and eating disorders. Theoretically, supplementing with Griffonia Seed can raise serotonin levels and provide relief from depression and insomnia.
Griffonia Seed should also regulate appetite through the increase in serotonin, leading to weight reduction in obese persons, while helping normalize the weight of people suffering from anorexia nervosa. Griffonia Seed has also been used in treating fibromyalgia and chronic headaches in order to reduce pain.
5-hydroxytryptophan (5-HTP) can be converted to serotonin in the body. It is often used for depression. It has less evidence for insomnia and anxiety.
