Melatonin, a hormone made by the pineal gland of the brain, helps regulate your sleep and wake cycles. Natrol® Melatonin is a nighttime sleep aid that assists with occasional sleeplessness, while also working to help reduce overall anxiety. It helps to establish normal sleep patterns to give you a more restful, relaxing sleep and in turn, better overall health by promoting a healthy immune system.† Adequate sleep is essential to overall health and performance, and plays a role in the ability to learn, create memories, solve problems and maintain a healthy mental outlook. By contrast, researchers have found that lack of sleep can result in mood swings and an inability to focus and respond quickly.† If you are just starting out and not sure how many mg is right for you, we recommend taking our 1mg tablets and move your way up as needed. † These statements have not been evaluated by the Food and Drug Administration.
