Melatonin is a natural hormone made by the body to help regulate sleep-wake timing. Supplemented melatonin may help you drift off to sleep faster. Melatonin has been found to have antioxidant effects and maybe the most effective lipophilic antioxidant. Melatonin has been found to interact with the immune system and promote a healthy inflammatory response. NutraBio uses only the best, and this product is no exception.
