They say, the best kind of sleep is deep sleep! Melatonin is a hormone in your body that plays a role in sleep. The production and release of melatonin in the brain is connected to time of day, increasing when it's dark and decreasing when it's light. Melatonin production declines with age. Our Melatonin is infused with a natural hormone that not only helps you fall asleep, but also keeps you in a deep sleep throughout the night!
