Melatonin is much more than the hormone of sleep. While it is a hormone secreted primarily by the pineal gland in the brain in response to darkness, and helps us become sleepy, it is also made in the eyes, retina, bone marrow, digestive system and lymphocytes.
Besides promoting an optimal sleep pattern, melatonin has been shown to be one of the most potent antioxidants in nature, protecting your body from free radical damage. Melatonin levels can affect cardiovascular function and women's cycles, and melatonin is a potent tumor suppressor that has been shown to protect against many types of cancer, including breast cancer and prostate cancer.
Many anti-aging researchers believe that melatonin is one of the keys to optimal health and longevity.
