Melatonin is a key component of your body's "sleep-wake" cycle, signaling your body that it is time to sleep. Aging, stress levels, diet, exercise, and external factors such as blue-light emitting smart phones, tablets and computers can disrupt and minimize our body's ability to produce melatonin. Natrol® Time Release Melatonin helps you fall asleep faster, stay asleep longer, and wake up rested.† †These statements have not been evaluated by the Food and Drug Administration.
