Why is healthy and restful sleep so important?
By now it should have penetrated even to the last strength athlete and bodybuilder: during intensive and brutal training sessions in the weight room and gym we only set a stimulus for building strength and new muscle mass. However, the actual building of strength and muscle takes place when we rest and recover from the workout. In other words, without adequate rest and recovery, gains in mass and strength cannot occur.
Just how important recovery is to most strength athletes is shown by the fact that hardly any of them would even think of foregoing their post-workout shake and other protein meals that follow later. Unfortunately, most overlook the fact that a healthy and restful sleep is at least as important for a quick and complete recovery. During sleep, when our bodies are at rest, the most important repair processes take place, without which no gains in strength and muscle mass would be possible. And without a restful sleep, we are not able to perform to the maximum during our next training session to stimulate a maximum build-up of strength and muscle mass.
A healthy night's sleep also helps your body cope better with stress - including training stress - and helps lower elevated catabolic cortisol levels that can result from stress and hard training, which can inhibit your muscle growth.
With our hectic lifestyles, adequate amounts of sleep are nothing more than a pipe dream for most of us. We forgo sleep because we have so much to do or are afraid of missing out, and try to banish our tiredness with the help of coffee or harder stimulants. And because of the stress many of us face, the quality of the little sleep we do get leaves a lot to be desired.
If you want to make maximum progress in the gym and build the body of your dreams, you can't go on like this!
Because we could no longer stand by and watch countless dedicated and potentially successful strength athletes and bodybuilders waste much of their time in the gym and weight room by not getting the amount of restful sleep and rest that is necessary for optimal gains in strength and muscle mass, we went to work and developed a sleep product that will help you reach your full potential while also making you more alert, rested and capable in your daily life.
The result of our efforts is Sleeper - the most comprehensive sleep and recovery supplement to ever leave our lab. Sleeper will help you fall asleep faster and sleep better through the night with the power of natural and safe ingredients. At the same time, Sleeper will help you get a deeper and more restful sleep, which means you can achieve maximum recovery and regeneration with less sleep to maximize your gains and performance in the gym, at work, and in your daily life.
But we wouldn't be GN Laboratories if Sleeper was "just" a sleep support product. That's why we've chosen Sleeper's ingredients to not only promote healthy and restful sleep, but also actively support your recovery and muscle building through a variety of different biological pathways.
Among other things, this includes an increase in the natural release of the body's own anabolic hormones that promote regeneration, such as IGF-1. In men, these ingredients also counteract a stress-induced reduction in the levels of the muscle-building male hormone.
Furthermore, by improving sleep, Sleeper can reduce catabolic cortisol levels caused by training and stress, thereby creating a more anabolic environment in the body that is more conducive to regeneration and building muscle mass and strength, which ultimately means nothing other than faster recovery and muscle building.
And as an added bonus, Sleeper can relax not only your mind, but also your hard-working muscles, alleviating exercise-induced muscle soreness and potential muscle soreness to get you ready for your next grueling workout session even faster.
If you want to speed up your recovery and optimize your performance while making maximum progress in building strength and muscle mass, Sleeper is exactly what you've been looking for!
On what active ingredients is the unique effect of Sleeper based?
In the development of Sleeper, we have combined the most effective natural ingredients to support healthy and restful sleep, paying special attention to active ingredients that can also promote rapid and optimal regeneration, as well as faster, maximum gains in muscle mass and strength through other mechanisms. It was at least as important to us to combine active ingredients that work synergistically together and mutually reinforce each other's effects.
It was also particularly important to us that Sleeper contains only natural ingredients that are safe for health, since the focus of this product is to support and promote natural, healthy sleep.
To show you that these are not just the same old empty promises that you may unfortunately be used to from other supplement manufacturers by now, we will take a look at each ingredient including its proven effects in the following sections.
Ashwagandha Root Extract
Ashwagandha is a medicinal plant with adaptogenic effects, which has been used for centuries in the field of Ayurvedic medicine. As its German trivial name "Schlafbeere" already suggests, Ashwagandha has a calming, stress-reducing effect and sleep-promoting effect. What is particularly interesting here is that Ashwagandha not only promotes easier falling asleep, but at the same time has a positive effect on the quality of the deep sleep phases, which are so important for recovery and regeneration, and also prolongs them. These positive effects on sleep are based, among other things, on the fact that active ingredients contained in Ashwagandha, known as withanolides, mimic the activity of a neurotransmitter in the brain, which reduces the activity of the neurons and thereby develops a calming effect.
But Ashwagandha has a number of other positive properties that can promote and accelerate your regeneration. Studies have shown that Ashwagandha can reduce stress-related elevated catabolic cortisol levels by up to 27%. This is especially important during recovery after hard and intense training sessions, which mean a strong physical stress for your body and almost inevitably result in increased cortisol release. Ashwagandha can thus help you to reach an anabolic, muscle-building state again faster.
In addition, ashwagandha can prevent a stress-induced reduction in testosterone levels in men and significantly increase natural testosterone production (3), which will result in faster recovery and faster gains in muscle mass and strength. This acceleration of regeneration has been demonstrated in clinical studies (3) in athletes, including a reduction in creatine kinase levels, which are a marker of muscle damage.
L-Theanine
L-theanine is an amino acid that occurs naturally in tea and is practically not found in any other food. From a chemical point of view, theanine is a derivative of the amino acid glutamine, which is capable of crossing the blood-brain barrier and exerting its effects directly in the brain.
In the human brain, L-Theanine can increase the release of the neurotransmitters dopamine, serotonin, and GABA, all of which, as shown in previous sections, have positive effects on your sleep and recovery after hard and intense workouts. L-Theanine works synergistically with many of Sleeper's other ingredients, further enhancing their effects.
In addition, theanine has positive effects on the alpha waves in the brain, which are so important during sleep (13). These alpha waves promote restful relaxation and can significantly improve the quality of your sleep, resulting, among other things, in an increased ability to concentrate the following day, which will allow you to concentrate better and with maximum focus on your training.
Furthermore, alpha waves inhibit the release of cortisol and other catabolic hormones, which - as has already been mentioned several times - can noticeably accelerate both your regeneration and your muscle building.
L-theanine also helps reduce stress and promotes relaxation, both of which can help you fall asleep. In addition to this, it reduces the stimulant effects of stimulants.
The sleep-promoting effects of L-theanine have been confirmed in numerous human and animal studies (14).
L-tryptophan
L-tryptophan is an essential amino acid that occurs naturally in food and is needed by your body as a substrate for the production of a whole range of important neurotransmitters and hormones of brain metabolism. Tryptophan is one of the few amino acids capable of crossing the blood-brain barrier. Once in the brain, tryptophan is used, among other things, to produce the neurotransmitter serotonin (6). Serotonin can not only improve mood and help fight depression, but is also involved in regulating healthy sleep. Thus, it should not be surprising that a tryptophan deficiency results, among other things, in sleep disorders, which can be effectively counteracted by isolated administration of free tryptophan.
Serotonin is so important for healthy sleep not least because it is the basic substance from which the so-called sleep hormone melatonin is produced in the human brain, which is responsible for regulating the sleep-wake rhythm. An increase in serotonin levels simultaneously results in an increase in melatonin levels, which promotes healthy and restful sleep. Melatonin not only promotes falling asleep, but also prolongs the REM and deep sleep phases that are so important for the body's recovery and regeneration (7, 8).
5-Hydroxytryptophan
5-Hydroxytryptophan, which is better known by the abbreviation 5-hydroxytroptophan, is a derivative of the amino acid tryptophan that occurs naturally in some foods and is also the intermediate product formed in the synthesis of serotonin from tryptophan in the human brain. Like tryptophan, 5-hydroxytroptophan can cross the blood-brain barrier, where it can be converted into serotonin or melatonin even more quickly and easily than tryptophan, since it is one synthesis step closer to serotonin.
How effective 5-hydroxytroptophan is in this respect is shown by the fact that this compound was the drug of choice for treating serotonin deficiency in the field of medicine before the development of selective serotonin reuptake inhibitors. To this day, 5-hydroxytroptophan is used in the medical field to treat sleep disorders because it stimulates melatonin production and promotes REM sleep, which is so important for recovery and regeneration, resulting in shorter time to sleep, better sleep quality, and longer sleep duration (5, 6). In principle, everything that has already been said about tryptophan applies to 5-hydroxytroptophan.
However, 5-hydroxytroptophan can contribute much more to faster and better regeneration, as it has direct effects on the body's production of a number of important hormones that play important roles in regeneration, metabolism and muscle building. Scientific studies conducted with athletes, which concluded that 5-hydroxytroptophan promotes regeneration and thereby enables more frequent and more intense training sessions, clearly show that this is not just pure theory.
In addition to increasing the body's production of growth hormone, 5-hydroxytroptophan can also increase levels of IGF-1, which is the body's most anabolic growth factor. In addition to this, 5-hydroxytroptophan can stimulate the formation of sattelite cells, which can fuse with muscle cells and thereby promote and accelerate regeneration and muscle growth. Of particular interest is the fact that 5-hydroxytroptophan promotes the formation of endogenous follistatin. Follistatin is an endogenous myostatin inhibitor that inhibits the formation of myostatin. By now, word should have spread that myostatin acts as a kind of natural brake on muscle growth in the human body and that a complete blockade of this inhibitor would allow quasi-unlimited muscle growth without natural genetic limits. Of course, 5-hydroxytroptophan doesn't go that far, but even a little less myostatin can work wonders when it comes to better recovery and faster muscle growth.
Melatonin
Melatonin is the human body's natural "sleep hormone" produced by the pineal gland in the brain. Melatonin, which is primarily secreted in the evening hours, is responsible for regulating the body's biological clock and the sleep-wake rhythm.
Sleep problems in general - and especially problems falling asleep - can often be traced back to insufficient natural melatonin production, for which there can be numerous reasons. In addition to an age-related decrease in natural melatonin production, stress, illness or quite banal triggers such as too much light can also lead to insufficient melatonin production.
Melatonin has been shown in numerous studies to help people fall asleep and not only reduce the time to sleep, but also significantly improve sleep quality (9, 10).
Another bonus is that melatonin can reduce the negative symptoms of jet lag by getting the body clock back on track (11, 12). The latter applies not only to jet lag, but also to shift workers, whom it can help cope better with constantly changing bedtimes.
In practice, a combination of compounds such as 5-hydroxytroptophan and tryptophan, which support natural melatonin production, combined with small amounts of melatonin in pure form has been shown to be the most effective way to alleviate sleep problems associated with insufficient endogenous melatonin production.
St. John's wort extract
St. John's wort is mainly known as a natural remedy for the treatment of depression and anxiety. Less well known is that St. John's wort may also have positive effects on sleep. The mechanisms thought to be responsible for this include stimulation of the GABA receptor - a key pathway for sleep-inducing chemicals in the brain - and stimulation of serotonin production, both of which can promote falling asleep.
In addition, studies suggest that St. John's wort may increase the duration of deep sleep by delaying REM sleep (17, 18). Deep sleep is the phase of sleep that is most important for physical and mental recovery, which in other words means that your sleep will be more restful and your recovery will be enhanced.
Warnings: Both melatonin and St. John's wort may interact with certain medications, increasing or decreasing their effects, which may lead to unwanted side effects and risks. Please discuss the use of Sleeper in advance with your treating physician if you are taking prescription or over-the-counter medications. Sleeper should never be combined with antidepressants, birth control pills, sedatives, or blood thinners.
