Let's start with the great news about a true sleep breakthrough…

If you long for a deep and refreshing night of sleep, and you also want to feel calm, at-peace, and productive during the day as a result, no matter what stressors life throws at you…

There’s finally an easy and safe formula made with research-backed ingredients that we guarantee you will LOVE.

However, you deserve to know WHY and HOW this powerful formula can help you, and to understand that you first need to know the 2 BIG PROBLEMS working against you.

Big Problem #1?
Poor Zzzs Can Be Very Unhealthy

It’s not discussed nearly enough, but poor sleep is easily one of the biggest issues of our time.

A recent Consumer Reports survey of 4,023 U.S. adults found that 68% of folks polled – or an estimated 164 MILLION Americans (that’s more than half the population) – struggle to get a good night’s sleep at least once per week!¹

You likely don’t need to be reminded how… poor sleep feels, whether you’re trying to silence all the “monkey chatter” in your head while struggling to first fall asleep…

Or you awaken in the middle of the night or way too early in the morning and you toss and turn fighting hard to go back to sleep.

And things only get WORSE with how poor sleep makes you feel during the day, ranging on a scale from “feeling edgy” to “EVERYTHING irritates me!” to flat-out “barely-walking-and-talking zombie.”

However, while how it makes you feel is bad enough, a poor night’s sleep can also:

→ Make You Hungry for Junk.

Lack of sleep increases hunger and cravings – particularly for high-carb, high-fat junk foods your body does NOT need. One study found that poor sleep increases levels of the “hunger hormone” called ghrelin, and decreases levels of leptin, a hormone that helps you feel full and satisfied. Just one night of bad sleep led study participants to eat 559 more calories – a 22% increase – the next day compared to after a full night of sleep. Bottom line here is that bad sleep increases hunger and can reduce your ability to say “NO” to tempting foods!

→ Make You Fat.

In addition to increased hunger for high-calorie junk foods, poor sleep can lead to a slower metabolism, which is not good news at all for healthy weight management.³ In fact, another study found that just 5 days of poor sleep led to a 1 ½ pound weight gain.⁴ Add that up over just a month or a year and you’ll see poor sleep is BAD NEWS for your waistline, indeed!

→ Make You Look Older.

Research also shows that sleep quality impacts skin function and aging. In one study, researchers found that women who didn’t get a full night’s sleep showed signs of premature skin aging and a decrease in their skin’s ability to recover after sun exposure. The study also found that poor sleep quality was associated with diminished skin barrier function and lower satisfaction with appearance.⁵

→ Lead to Distraction and Forgetfulness.

You’ve certainly felt “foggy brained” after a bad night of sleep, right? Well, research shows not getting a full night’s sleep may literally impair memory… learning… attention… resilience… and logical reasoning!⁶ You see, it’s during sleep that the brain’s “clean-up crew” (called the glymphatic system) is most active, clearing out potentially neurotoxic waste from the brain.⁷

→ Lead to Bad Decisions and Risky, Self-Destructive Behavior.

Multiple studies have shown that an inadequate night of sleep adversely affects decision making. For instance, one study found that just two nights of short sleep impaired decision making and increased risk-taking behavior.⁸ These effects appear to be due to reduced regional cerebral metabolism within the prefrontal cortex, the brain region most responsible for higher-order cognitive processes, including judgement and decision making.

And the potentially harmful effects of poor sleep do not stop there!

Research shows it can, indeed, make you moody, irritable, angry, and feeling “down in the dumps”^9,10… It can make everything feel more challenging than it really is, such as your work¹¹… And it can make you slow to react, which can be annoying in areas like work, sports, and hobbies.¹²

The bottom line?

Poor sleep—just a single night, in fact—can make life far more difficult than it ought to be!

Feeling STRESSED?

Feel like you suffer from too much stress? Well, according to a Stress in America survey conducted by the American Psychological Association, stress keeps more than 40% of adults lying awake at night. Ironically, 45% of people report feeling more stressed after not getting enough sleep.¹³ YES, it can seem like a vicious cycle. The good news is, there’s finally a way out of it…

Big Problem #2?
Overhyped Solutions

Because poor sleep can affect virtually every aspect of life, it’s little wonder that people are willing to spend so much to help get a good night’s rest. According to a 2020 report by Infinium Global Research titled “Sleep Aids Market”, the global sleep aids market was valued at over $70 BILLION in 2018, and it’s estimated to exceed $114 billion in 2025, with a compound annual growth rate of 7% over the forecast period (2019 - 2025).¹⁴ That’s more than the GDP of many countries!

HOWEVER…

A Consumer Reports investigation of these so-called “solutions” found that some may “…be limited in their effectiveness and prone to potentially dangerous misuse”.¹

Toward that end, here are two key things to watch out for with some sleep “solutions”:

Long-term use of certain sleep agents may result in dependence and tolerance. On one hand, this means that more has to be taken over time to get the desired effect. On the other hand, it means that their discontinuation can cause withdrawal symptoms.¹⁵

Some sleep agents are known for a variety of negative side effects, such as drowsiness or feeling hungover.

Now, poor sleep impacts adults of all ages today. However…

Are You in Your “Middle Years” or “Golden Years”?

Because, generally speaking, studies show that age has an inverse relationship with quality of sleep. Put plainly: poor sleep and getting older go hand-in-hand.

As just one example, in one study, researchers assessed sleep quality among a group of 170 men and women adults (age 18 - 60+), and they found that sleep quality in a group of people ages 46 – 60 was 59% worse than participants in the 18 – 30-year-old group.¹⁶ Various other studies further illustrate this inverse relationship between age and sleep quality,^17,18 but the bottom line is…

The older you are, the more important it is to take proper action against poor sleep! Therefore, here are…

6 Key Tips to Enjoy a Good Night of Sleep

Try to maintain a consistent bed and wake time every day, and get to bed before 11 pm.
Ensure a quiet, cool and dark environment in your bedroom
Avoid caffeine and other stimulants 6 hours or more prior to sleep
Block blue light and/or avoid light-emitting technology devices in the hours prior to sleep (e.g., avoid screens and shut off electronics at least an hour before bed)
Implement stress management techniques, such as setting boundaries, practicing yoga, meditating, taking a leisurely walk, and breathing deeply and slowly.
Exercise daily, but not too late, as that can raise core body temperature and levels of hormones that can keep you awake.

The 7 ESSENTIAL Nutrients for Zen-like Zzzs
(and feelings of calm and peace during the day, too!)

If you’re currently not doing many or even most of the 6 steps above, please do not worry – just take it step-by-step implementing them more and more into your life.

It’s also important to know that putting the right nutrients into your body makes a world of difference to support deep, refreshing, and restorative sleep (and all the benefits that come with it, including greatly reduced feelings of stress during the day and feeling more focused and upbeat!)

Toward that end, nature provides many helpful ingredients, but these are 7 research-based nutrients that are HIGHLY EFFECTIVE for Zen-like Zzzs:

L-Theanine

This relaxing amino acid helps support a healthy balance of compounds called neurotransmitters (such as serotonin and glutamate) to provide nutritional support that promotes relaxation, feelings of well-being, sleep quality and a healthy stress response.^19–21

Melatonin

Research shows this well-known natural compound can provide powerful support for reducing the time it takes to fall asleep… increasing total sleep time… increasing the amount of time sleeping in bed relative to overall time in bed… and improving overall sleep quality.^22,23 NOTE that melatonin levels in the body typically decline with age, making supplementation an increasingly important consideration as you age.²⁴ ALSO NOTE that contrary to myth, melatonin is not habit-forming and typically produces no “sleep-hangover” or other concerning side effects.^23,25

Magnesium

This essential mineral is crucial for many processes in the body, including a healthy stress response.²⁶ NOTE that many people – up to 75% of folks, according to some population-based research – don’t get enough magnesium in their daily diet.^27-29

Lemon Balm Extract

Lemon balm, also known as “Sweet Mary,” has been treasured for its health benefits by European and Mediterranean cultures for over 2000 years. And science shows those cultures were right, as it can provide powerful support for improving overall sleep quality for those experiencing difficulty sleeping due to stress… reducing how long it takes to fall asleep³⁰… reducing occasional feels of worry and uncertainty^31,32… and promoting healthy brain function and healthy moods!^33,34

Chamomile Extract

Perhaps the most famous herb to help with sleep, chamomile has been shown in research to support calm nerves and the easing of feelings like agitation and worry.³⁵ This is likely largely due to “apigenin,” a key component in chamomile that may help support a healthy balance of neurotransmitters (such as GABA) to help promote relaxation.³⁵

Passion Flower Extract

Derived from a special climbing vine that is native to the southeastern U.S. and Central and South America, passion flower is widely used for sleep support.³⁷ And research shows it may indeed support sleep duration, sleep latency (the amount of time it takes to fall asleep), and support overall sleep quality.^37,38

Vitamin B6

Many people think of B6 as being important for the metabolism of protein, fats, and carbs, but it’s also involved in the process of converting tryptophan to serotonin, which is the precursor to the sleep-regulating hormone melatonin.³⁹ In other words, consuming adequate B6 is important to support the body’s natural production of melatonin. Interestingly, it may also provide strong support for “good dreaming” because it may help enhance dream lucidity and the amount of dream content recalled!⁴⁰

The GREAT News: You Can Finally Get ALL 7
Of These Key Nutrients in ONE Easy-to-Take Capsule

The 7 nutrients covered above provide very powerful support for deep, refreshing, restorative sleep.

The problem is, it can be time-consuming and quite expensive to track down and buy several of these in top-quality forms, much less all of them.

As mentioned at the start, though, there’s finally a SOLUTION…

It’s called Zen-Zzz, and you’ll just take 1 or 2 easy-to-swallow capsules, 30 minutes before bed, to support what we believe you’ll agree is the best sleep of your life (and feeling calm, cool, and collected during the day, too, no matter what life throws your way!)

Because, YES, Zen-Zzz provides you all 7 of the key sleep nutrients – each in clean, premier-quality forms.

This includes premium quality L-Theanine… Melatonin… Magnesium… Lemon Balm Extract… Chamomile Extract… Passion Flower Extract… and Vitamin B6.

PLUS, it matters greatly what you’re not getting with Zen-Zzz.

Zen-Zzz is FREE of artificial sweeteners, flavors, colors, and preservatives. It’s non-GMO and soy-free, gluten-free, and dairy-free.

And finally, YES, it’s 3rd-party lab tested to ensure purity, potency, and safety.

Each bottle of Zen-Zzz provides you 60 capsules, which means a month or more of support for those “Zen-like” Zzzs, because, again, it’s SIMPLE TO TAKE: Just take 1 or 2 capsules, depending on your needs, before bedtime!
