How It Works...
It All Starts With Deactivating Nighttime Overthinking.
In a world that never seems to slow down, our minds are often stuck in a cycle of relentless activity, racing with thoughts and stress long after the day is done.
This overthinking keeps our bodies tense and prevents the natural relaxation needed for quality sleep.
This is where 4GREATSLEEP shines through.
At the heart of 4GREATSLEEP is an innovative approach called the Nocturnal Worry Release System (NWRS).
NWRS is the breakthrough formulation that powers our 4GREATSLEEP supplement. It combines natural stress-reducing amino acids and calming herbs that deactivate nighttime overthinking, promoting deep relaxation and uninterrupted sleep.
4GREATSLEEP’s Nocturnal Worry Release System combines scientifically-backed ingredients to address both the mental and physical barriers to quality sleep:
- It stops overthinking in its tracks: Stress-reducing amino acids like GABA and L-Tryptophan calm an overactive mind.
- It encourages relaxation: Calming herbs like Hops and Ashwagandha promote relaxation and prepare your body for sleep.
- It supports the natural sleep cycle: Ingredients like Melatonin ensure you fall asleep faster and stay asleep longer.
When you make 4GREATSLEEP a part of your nightly routine, you’ll:
- Drift off effortlessly without tossing and turning.
- Stay asleep longer and wake up feeling truly refreshed.
- Wake up clear-headed and ready to tackle the day.
NWRS works with your body to naturally calm your mind, making it easier to drift into restorative sleep and wake up feeling refreshed.
4GREATSLEEP is designed to break this cycle by delivering a targeted blend of calming nutrients and herbs that your body needs but can’t always get from diet alone.
By soothing your mind, reducing stress, and supporting your natural sleep cycle, 4GREATSLEEP helps you drift into deep, restful sleep and wake up feeling refreshed and ready to take on the day.
4GREATSLEEP's Science-Backed Ingredients:
The Perfect Sleep Cocktail
We Started With The 3 Most Important Herbs For Better Sleep
Supports Natural Sleep Cycles and Promotes Restful Sleep
Melatonin is a hormone naturally produced by the body to regulate your sleep-wake cycle, playing a vital role in signaling your body when it’s time to rest.
Research shows that melatonin helps people fall asleep faster and stay asleep longer, making it ideal for anyone struggling with disrupted sleep or nighttime restlessness.
By working with your body’s natural rhythms, the melatonin in 4GREATSLEEP promotes deeper, uninterrupted sleep without the grogginess associated with many synthetic sleep aids. Our precise dosage ensures effective results, helping you wake up feeling refreshed and rejuvenated.
Relaxes Muscles and Calms the Mind for Better Sleep
Magnesium is a critical mineral involved in hundreds of biological processes, including muscle relaxation and nervous system regulation, both of which are essential for restful sleep.
Studies have shown that magnesium supplementation can improve sleep quality by calming the mind, reducing stress, and easing physical tension. It’s particularly effective for those experiencing restlessness or difficulty relaxing before bedtime.
4GREATSLEEP uses a bioavailable form of magnesium to ensure it’s easily absorbed by the body, helping you unwind naturally and drift into restorative sleep with ease.
Calms the Mind and Reduces Stress for Easier Sleep
GABA (Gamma-Aminobutyric Acid) is a naturally occurring neurotransmitter that plays a key role in calming the nervous system and promoting relaxation.
Studies have demonstrated that GABA helps reduce overthinking, lower stress levels, and quiet the mind, making it easier to fall asleep and stay asleep. It’s especially beneficial for those whose racing thoughts keep them awake at night.
4GREATSLEEP includes an optimal dose of GABA to help your body transition from wakefulness to restful sleep naturally, without the need for harsh chemicals. By calming your mind and body, GABA ensures a more peaceful and uninterrupted night’s rest.
These 3 Ingredients Alone Will Transform Your Sleep ~ But To Make It Even More Powerful, We Also Included:
Promotes Relaxation and Reduces Restlessness
Hops, commonly known for their role in brewing, have a long history of use as a natural sedative. They are particularly effective in promoting relaxation and easing tension, making them a powerful ally for improving sleep quality.
Studies show that hops can help calm an overactive nervous system, reduce restlessness, and support the transition into deeper, more restorative sleep.
4GREATSLEEP includes a carefully balanced dose of hops to help you unwind naturally and create the perfect conditions for a peaceful night’s sleep.
Reduces Stress and Enhances Sleep Quality
Ashwagandha, a revered adaptogenic herb, is renowned for its ability to reduce stress, lower cortisol levels, and improve overall sleep quality. Its calming properties make it ideal for people struggling with anxiety or stress-induced insomnia.
Scientific research highlights Ashwagandha’s ability to promote relaxation and help the body adapt to stress, enabling you to fall asleep faster and enjoy deeper, more restorative sleep.
4GREATSLEEP incorporates an appropriate dose of Ashwagandha to soothe your mind and body, ensuring you wake up refreshed and revitalized.
Supports Serotonin Production for Better Sleep
L-Tryptophan is an essential amino acid that plays a crucial role in producing serotonin, a neurotransmitter that regulates mood and promotes relaxation. Serotonin is then converted into melatonin, which helps regulate your sleep-wake cycle.
Research shows that L-Tryptophan can help you fall asleep faster and improve sleep duration and quality, making it a vital component of any effective sleep solution.
4GREATSLEEP uses L-Tryptophan to naturally enhance serotonin and melatonin levels, creating a calming effect that helps you drift into a deep, peaceful sleep.
