Researchers say that melatonin is perfectly safe and also shows promise in preventing cancer and the build-up of cholesterol. Melatonin originates in the pineal gland, the part of the brain that keeps the body's clock in synch. When the sun goes down, the eyes signal the gland to start pumping melatonin. In response, the body temperature falls, metabolism slows and we prepare for sleep. As we age, the pineal gland pumps less and less melatonin, which may be why many elderly people have trouble sleeping.
