Did you know that plastic storage containers might have a devastating effect on your sleep? What you may have thought is that water resting in plastic can increase plastic content in your water. Gulp that down, and you may face an unwelcomed accumulation of toxins that disrupt the necessary systems that regulate sleep.
These systems ensure you are in the highest spirits during the day and well-rested at night. Imagine how chaotic things might be if your sleep patterns changed out of nowhere. Numerous studies confirm that sleep deprivation can seriously ruin your quality of life. Where are we headed with this? Well, the only way to find out is to stick with this review of Sleep Revive until the very end.
What is Sleep Revive?
Sleep Revive is a deep sleep supplement that supports the natural sleep cycle. When taken as directed, it can help increase relaxation, calm the mind, and ultimately rejuvenate sleep. According to the creators, Critical Nutrition Labs, this formula aims to counteract the effects of two particular toxins on our circadian rhythm, a system known to influence our mental, physical, and behavioral changes.
The moment this duo enters the bloodstream, it supposedly wreaks havoc on the body’s 24-hour internal clock, which oversees cycles of wakefulness and sleepiness (also known as our circadian clock). This could disrupt one’s sleep.
Days of high productivity will turn into increased sleepiness, memory problems, and so on. Likewise, nights of restful sleep might be filled with increased alertness instead. As repetitive as this might be, poor sleep patterns affect several health areas, leading to chronic conditions. Now, let’s face the elephant in the room: which two toxins are the Critical Nutrition Labs team referring to? The answer will be revealed in the next section.
Sleep Revive: Try it now, you won't be disappointed!
How does Sleep Revive work?
Previously, we highlighted that Sleep Revive reverses the consequences of two toxins that affect our sleep cycle. The culprits are none other than bisphenol-A (BPA) and phthalates. BPA is an “industrial chemical used to make certain plastics and resins.” The same source reported that BPA in BPA containers could seep into food or beverages, entering the human body. Research on the effects of BPA on well-being has shown that plastic might increase blood pressure, type 2 diabetes, and cardiovascular disease and may harm the brain and prostate glands of fetuses, infants, and children.
One study examining the implications of BPA on sleep adequacy in U.S. adults found that exposure to BPA may be associated with fewer hours of sleep. The latest research on this relationship confirmed that even a low dose of BPA can have devastating effects. This animal study of adult mice found that low doses of BPA changed their daily activity, social behaviors, and brain activity. Such a disruption is linked to increased suprachiasmatic nucleus (SCN) neurons, which affect the circadian clock.
Phthalates, which are yet another group of chemicals, are used to make plastic soft and flexible. Interestingly, they are also in our bodies. Although phthalates do not live forever in our tissues, accumulated exposure might negatively impact reproductive health, child development, and many organ systems. Excessive exposure could even increase the chances of dying (even from cancer). Like BPA, phthalates have also been demonstrated through modeling that increased exposure to phthalates led to a significant increase in sleep problems (at least in females, based on this study).
People have overlooked this angle for a long time, but with more research coming to light, it’s no wonder there’s growing awareness about BPA-free products (as there should be).
Now that the foundation of this formula is out of the way let’s go through the ingredients.

What’s inside each Sleep Revive serving?
Each Sleep Revive serving consists of:
Magnesium (225 mg)
Magnesium is a nutrient that acts as a cofactor in over 300 enzyme systems and is responsible for different biochemical reactions in the body. In the context of sleep, there are numerous mechanisms worth considering. First, it regulates gamma-aminobutyric acid (GABA) levels in the central nervous system, calming the CNS down. As such, a sedative effect is stimulated, pushing people into sleep. Second, it has been shown to block another neurotransmitter called the N-metyl-D-aspartate receptor. Doing so relaxes the muscles, improving general relaxation and sleep.
Third and central to sleep is magnesium’s effect on melatonin (the sleep hormone) production. A decrease in melatonin disrupts the circadian rhythm, causing undesirable changes to our day-night cycle. Finally, magnesium might lower cortisol levels, preventing individuals from remaining consistently in the fight-or-flight response. Magnesium’s role transcends sleep, as it may help lower the risk of being diagnosed with type 2 diabetes, lower blood pressure levels, reduce the symptoms of migraines, and lower the risk of osteoporosis.
Valerian Extract (250 mg)
Valerian is an herb called “nature’s Valium” several times, as it has been historically used to treat insomnia. One source that assessed its effectiveness in inducing sleep summarized the findings of several studies before concluding. Their research shows this plant consists of diverse compounds that might benefit sleep. These include valepotriates, monoterpenes, sesquiterpenes, carboxylic compounds, lignans, and even GABA. Valerenic acid and valerenol act on GABA the same way magnesium does. This duo might destroy enzymes known to eliminate GABA, thereby helping regulate sleep and mood.
Preliminary research on valepotriates pointed to their anti-anxiety and antidepressant effects, but more research will be needed to confirm this. Aside from directly influencing sleep, some indirect avenues, as hinted briefly, include easing symptoms of anxiety and stress, leaving individuals feeling somewhat sedated. A 500 to under 800 mg valerian dose might help people fall asleep faster, remain asleep longer, and reduce how often they wake up in the middle of the night.
L-Theanine (200 mg)
L-theanine is an amino acid. Unlike most amino acids involved in protein synthesis, l-theanine is a non-proteinogenic amino, meaning it doesn’t contribute to protein synthesis. Instead, it has been proven to relax the brain, reduce stress, and possibly induce sleep. One review that covered this non-proteinogenic amino acid’s effect on sleep confirmed that though it isn’t a sedative, it does promote good quality sleep through anxiolysis. In other words, it might reduce anxiousness. While one might argue that reducing anxiety makes it a sedative, its effect is too mild to be classified as such.
Another source that covered the mechanism by which l-theanine induces sleep explained that it has no problem crossing the blood-brain barrier, allowing it to affect the central nervous system dramatically. Moreover, it might prevent glutamate from binding to cells in the brain, which means ideal levels of GABA, dopamine, and serotonin and decreased levels of our fight-or-flight hormones. Interestingly, doses ranging from 50 to 200 mg might increase alpha brain waves, attributed to increased relaxation or drowsiness.

Lemon Balm Extract (150 mg)
Lemon balm extract, made from the Melissa officinalis plant, is a member of the mint family. Like many of the ingredients in Sleep Revive, it is renowned for its calming effects. Lemon balm was heavily used in the Middle Ages to “reduce stress and anxiety, promote sleep, improve appetite, and ease pain and discomfort from indigestion,” writes one source. Regarding sleep and anxiety, this ingredient is usually paired with similar plants and herbs (e.g., valerian, hops, and chamomile) to reduce stress and promote sleep.
From the looks of things, a dose of lemon balm extract at 600 mg might significantly improve mood, calmness, and alertness and stimulate sleep among people with minor sleep problems. Does insomnia count? Probably not, especially if this extract is taken alone. As for the underlying mechanism, a pilot study reported that lemon balm extract, combined with other herbs, might prevent the breakdown of GABA. When this neurotransmitter is broken down into smaller molecules, the risk of neuronal firing rises, disrupting sleep-wake cycles, memory, and overall brain function.
Rutaecarpine (100 mg)
Rutaecarpine is an alkaloid derived from the Chinese Euodiae Fructus herb. Historically, it has been used as a treatment for gastrointestinal disorders, headaches and related symptoms, and diarrhea episodes, to name a few. Preclinical models have proven that rutaecarpine, among other alkaloids in Euodiae Fructus, has anticancer, antibacterial, anti-inflammatory, and anti-cardiovascular disease effects.
The same review underscored the need for further research to confirm its utility in human nutrition and health. In Sleep Revive, rutaecarpine traps and removes large amounts of BPA and phthalates from the body. For caffeine consumers, this compound breaks down caffeine in the body while enhancing the liver’s ability to process caffeine. This might be useful for those whose sleep cycles have been affected by caffeine intake.

Concluding Remarks
Based on the analysis above, Sleep Revive was formulated to reverse the effects of BPA and phthalates on our sleep cycles. This formula aims to mitigate the damages caused by accumulated BPA and phthalates. They claim Sleep Revive achieves this by inducing sleep by increasing GABA activity (and blocking enzymes that catabolize GABA), relaxing the mind, easing symptoms of depression, anxiety, and stress, eliminating caffeine from the body, and boosting melatonin levels.
Sleep Revive is unique in that the Critical Nutrition Labs team avoided using melatonin supplements. While melatonin puts people to sleep, it increases feelings of grogginess in the morning. Also, it might induce mild side effects, introduce changes to hormones, and induce the feeling of needing it to sleep. Such habit-forming effects are unlikely with Sleep Revive, which is reassuring.
The question is whether it is better to supplement with a single underlying mechanism or multiple mechanisms. The answer varies from person to person, with each option offering its own set of pros and cons. In light of this, individuals should use this review as a starting point for their research to see whether Sleep Revive is a good fit.
