The body uses tryptophan to help make melatonin and serotonin. Melatonin helps regulate the sleep-wake cycle, and serotonin regulates appetite, sleep, mood, and pain. The liver can also use tryptophan to produce niacin (vitamin B3), which is needed for energy metabolism and DNA production. Tryptophan supplements can be used as natural relaxants to help relieve insomnia. Tryptophan can promote relaxation & positive mood. Dose: Take 2-1 capsules 2 to 3 times daily on empty stomach final dose before sleep.
