What Is Melatonin?

Melatonin and Your Body

Melatonin is a hormone that is naturally produced by the pineal gland in the brain. It essentially tells the body when to fall asleep and when to wake up. It does this by increasing the amount of melatonin in your system as the sun sets, making you feel sleepy, and decreasing the melatonin in your system as the sun rises, helping you wake.  

You create the most melatonin when you’re around 3 years old, and this steadily decreases as you get older. People age 70 or older have about a quarter of the amount of melatonin in their systems during sleep that teenagers do. While why this is the case is not known, it’s theorized that melatonin has important cognitive and development benefits. 

And, the amount of melatonin your body produces isn’t just based on the time of day or your age, it’s also impacted by the seasons. When days get shorter and darker during winter months, your body may produce melatonin in different amounts and at different times.

Your Circadian Rhythm

There is another element to your sleep schedule that may be impacting your sleep satisfaction: your circadian rhythm. Also known as your sleep-wake cycle, your circadian rhythm is your brain’s internal sleep clock. When it’s working as it should, you get drowsy around the same time each night and you wake up around the same time each morning. Your circadian rhythm may be different than those around you. So-called “night owls” and “morning birds” have different circadian rhythms, but by keeping predictable sleep schedules, both types should wake feeling well-rested and stay energized throughout the day. 

You can disrupt your circadian rhythm by staying up later than usual, sleeping in on weekends, and frequently traveling across time zones. A disrupted circadian rhythm can leave you feeling groggy when you should awake or restless when you should be asleep. 

Melatonin Supplements & ZzzQuil PURE Zzzs

A melatonin supplement can be a safe way to increase the amount of melatonin in your system when you’re having trouble falling asleep. Unlike more powerful prescription sleep aids, melatonin is a supplement, and can help you fall asleep naturally*. Melatonin supplements are also a great choice when experiencing daylight savings time, jet lag, or schedule changes that may affect your circadian rhythm.   

So what separates ZzzQuil PURE Zzzs from other melatonin supplements? The melatonin in our PURE Zzzs products affects your brain in the same way that the melatonin your body naturally produces does. It works by triggering your circadian rhythm to recognize that it’s time for sleep. What makes us different is our mindfully crafted formula.
