WHY CHOOSE SLEEPSYL

FOR BLISSFUL, UNINTERRUPTED SLEEP?

Most other sleep aid supplements do not provide a dual-action solution that aims to relax and calm your mind to grant you a high quality night's sleep as well as combat fatigue symptoms to ensure you wake up refreshed and alert. Most sleep aid supplements do not include L-ornithine, an amino acid that has proven to be effective in reducing stress and improving sleep quality. Most other supplements do not have the dynamic duo of Valerian and Hops, which together function as an anxiolytic to induce a sense of calm. Moreover, this pairing helps increase GABA (gamma-aminobutyric acid) levels in the brain which are responsible for calming the active neurons in the central nervous system to promote restful sleep. Most other sleep aids do not include a potent 6 mg serving of Melatonin which is essential for balancing circadian rhythms to support a healthy sleep routine.

Due to extensive research and our firm understanding of what makes an effective sleep aid, we have created a product that is uniquely formulated to boost relaxation levels, regulate sleep cycles, improve the quality as well as the duration of sleep, promote serotonin levels for a better mood and get rid of morning grogginess leaving you feeling fresh and alert for the rest of your day.

Each ingredient was carefully selected, based on years of research and clinical studies. Over 20 years of safety and efficacy research has been documented on what ingredients should be included in a quality sleep aid to get the very best results possible with absolutely no side effects.

HOW DOES

SLEEPSYL WORK?

White Sleepsyl supplement bottle with blue label.

Sleepsyl is formulated with clinically proven ingredients that provide the ultimate sleep aid support to help shorten the ‘awake’ period, sleep for longer and deeper as well as prevent feelings of grogginess in the morning. The ingredients in Sleepsyl were selected by a team of doctors and scientific researchers based on clinical data and designed to get results more effectively than any other sleep aid available.

Sleepsyl is your ultimate solution against sleepless nights. Key herbs such as Valerian, Hops, Chamomile and Lemon Balm relieve anxiety or stress to support peaceful sleep. Melatonin is included to help balance circadian rhythms to restore healthy sleeping patterns. Sleepsyl also contains L-ornithine, an amino acid that helps boost sleep quality to ensure you wake feeling refreshed and alert.

This dual-action, top quality sleeping aid provides the 4 essential elements of success: Relax, Improve, Restore and Boost - nourishing the body to ensure an optimal night’s sleep.

In terms of quality and purity of ingredients, there is nothing else in the market that comes close to Sleepsyl.

    STEP #2 - IMPROVE

    Sleepsyl includes ingredients such as Valerian and Hops that help increase GABA (gamma-aminobutyric acid) levels in the brain. Healthy GABA levels help improve the two deepest sleep periods: slow-wave sleep and REM which in effect ensure a higher quality sleep.

    STEP #4 - BOOST

    The unique combination of ingredients found in Sleepsyl is especially effective at boosting levels of Serotonin. Serotonin has been shown to be beneficial in stabilizing mood and general feelings of well-being and happiness to ensure you wake feeling rested and revitalized.

What's THE WORD ON Sleepsyl?

If you're ready, join the thousands of Americans who have already experienced the benefits and seen the results!

Sleepsyl is not like any other sleep aid supplement I’ve tried. As soon as I take these capsules, very shortly after I already feel sleepy. The best part for me is that I wake up refreshed in the morning. I really feel like I’ve had a deep sleep and don’t feel tired at all during the day.

Sleepsyl does exactly what it says it will do. It has helped me calm my nerves in the evening, helps me relax and fall asleep. This really helped turn things around for me. I’ve been going through a very stressful situation which was affecting my sleep which obviously then makes it worse, because a...

I’ve been taking these for about a week now and am quite pleased. They make me tired enough to fall asleep easily but without leaving that groggy feeling in the morning. So far I haven’t had any bad side effects from these. Sleepsyl gets my 5 star approval for sure!

I work in shifts, so my hours are all over the place which makes it extremely difficult to keep a regular sleeping pattern. I struggle to fall asleep many times when my hours are not consistent.

I have a problem that the minute I lie down I have a million thoughts going through my head all at once and I can’t seem to manage to clear my mind and fall asleep. It lands up that I only get a couple of hours of sleep a night and then struggle to function during the day. Sleepsyl has saved my...

I had surgery a while back and for a long time after I struggled with falling asleep. I happened to come across Sleepsyl and decided to give it a try. I felt an immediate effect.

I feel like I’ve tried every sleep aid available! I’ve tried so many I could write a book. This is the only one though that does it all. It helps me fall asleep quickly, and I don’t have any feelings of grogginess in the morning. I was super skeptical since everything else I tried seemed to fail....
