Sleep&Relax
(number of products: 136)Sleep & Relax is the key to optimal regeneration, better sleep, and stress reduction for physically active people. Gym training, fitness classes, martial arts, or other forms of activity require not only effort but also proper support for the body in the regeneration process. Products in this category, such as melatonin, ashwagandha, magnesium, or GABA, help calm the nervous system, improve the quality of sleep, and accelerate muscle regeneration. Thanks to them, you can train harder, achieve better results, and avoid overtraining. During sleep, the body rebuilds damaged muscle fibers, replenishes glycogen stores, and regulates hormone levels such as testosterone and cortisol. Sleep deprivation leads to decreased performance, slower regeneration, and even an increased risk of injury. Use intelligent support for your sleep and maintain the best results!

What are Sleep & Relax supplements, and how do they work?
Supplements in this category are carefully composed mixtures of plant extracts, amino acids, adaptogens and substances supporting the production of neurotransmitters responsible for sleep, peace, and regeneration. Their main task is:
- Shortening the time it takes to fall asleep
- Increasing the depth of sleep
- Reducing the frequency of awakenings
- Calming the nervous system
- Reducing cortisol levels (stress hormone)
Why is sleep the most important thing for an athlete?
Have you ever wondered what really happens in your body when you sleep? This is not a time of passivity. This is the period of your body's most intensive work, a real regeneration factory.
Nighttime Muscle Protein Synthesis and Fiber Regeneration
During training, your muscle fibers undergo micro-damage. This is a natural and desirable process that stimulates them to grow and adapt. However, the repair and build-up process (hypertrophy) occurs mainly at night, during deep sleep phases (NREM). This is when the body releases the largest amounts of growth hormone (GH), a key anabolic player that increases muscle protein synthesis. Short or shallow sleep drastically reduces GH levels, which directly translates into slower regeneration, smaller gains in strength and muscle mass, and an increased risk of overtraining.
Regeneration of the Nervous System - Reset for Your "Computer"
Intensive physical exercise is a huge burden not only for the muscles, but above all for the Central Nervous System (CNS). It is responsible for the recruitment of motor units, coordination, and strength of muscle contraction. An overworked CNS is a guarantee of a decline in form, lack of "spark" in training, and reduced motivation. Deep sleep allows the brain to "cleanse" of metabolic toxins (such as beta-amyloid) and fully regenerate the CNS. Thanks to this, you wake up with a "clear head", ready to take on new challenges and maximum concentration on training.
Hormonal Regulation and Your Sports Form
Sleep has a fundamental impact on hormonal balance, which determines your body composition and overall fitness.
- Cortisol vs. Testosterone: Sleep deprivation leads to chronically elevated levels of cortisol, the stress hormone. Cortisol has a catabolic effect - it destroys muscle proteins and promotes the accumulation of fat tissue, especially around the belly. At the same time, too little sleep reduces the production of testosterone, a key anabolic hormone. Such a hormonal balance of power is a recipe for disaster for any athlete.
- Leptin and Ghrelin: Sleep also regulates the hormones responsible for appetite. Lack of sleep causes a decrease in leptin (the satiety hormone) and an increase in ghrelin (the hunger hormone). In practice, this means ravenous hunger pangs during the day, especially for high-calorie, unhealthy foods, which effectively sabotages any reduction diet.
What dietary supplements for sleep should you choose?
Our offer is no coincidence. Each product and each ingredient has been selected based on solid scientific evidence and years of practice in working with athletes. Get to know your allies in the fight for better sleep.
Melatonin - Your Natural Sleep Regulator
Melatonin, often called the "hormone of darkness", is produced naturally by the pineal gland in the brain after dusk. It sends a signal to the entire body that it is time to rest. Unfortunately, exposure to blue light (smartphones, computers), shift work or intensive evening training can disrupt its production.
How does melatonin work? Melatonin supplementation helps shorten the time it takes to fall asleep, regulates the circadian rhythm (especially useful for jet lag) and improves the overall quality of sleep. For athletes, this is invaluable support in stabilizing the sleep-wake cycle, which is crucial for regular, effective regeneration.
GABA (Gamma-Aminobutyric Acid) - Soothing for the Nervous System
GABA is the main inhibitory neurotransmitter in the central nervous system. Its task is to "slow down" the activity of neurons, which leads to a feeling of relaxation, calmness and reduction of nervous tension. In a world full of stress and after a hard workout, when the nervous system is "speeding up", GABA acts as a natural brake.
How does GABA work on sleep? GABA supplementation helps reduce anxiety, facilitates calming down before sleep and promotes deeper phases of sleep. It works synergistically with melatonin, creating ideal conditions for falling asleep and uninterrupted rest.
ZMA (Zinc, Magnesium, Vitamin B6) - Nighttime Anabolic Support
ZMA is a synergistic combination of three key microelements for athletes. This is not an ordinary vitamin set – it is a formula designed specifically for night-time regeneration.
- Zinc: It is involved in the synthesis of proteins and testosterone. Its deficiencies are common in physically active people, which can negatively affect anabolic processes.
- Magnesium: Crucial for the functioning of the nervous system and muscles. It helps in muscle relaxation, reduces spasms and facilitates falling asleep by activating GABA receptors.
- Vitamin B6: Increases the absorption of zinc and magnesium, and also takes part in the production of neurotransmitters, including serotonin, which is a precursor of melatonin.
How does ZMA work? The ZMA complex supports deep sleep, optimizes the night-time production of anabolic hormones (testosterone, IGF-1) and contributes to the full regeneration of the nervous and muscular systems.
Adaptogens to the Rescue - Ashwagandha and L-Theanine
Adaptogens are a unique group of plants that help the body adapt to unfavorable conditions, including physical stress and mental.
- Ashwagandha (Withania somnifera): The queen of adaptogens. Used for centuries in Ayurvedic medicine to reduce stress and improve vitality. Ashwagandha effectively lowers cortisol levels, which is crucial for athletes. Lower cortisol means better regeneration, less muscle catabolism and better well-being. It helps calm the mind and prepare the body for sleep.
- L-Theanine: An amino acid found naturally in green tea leaves. It has the unique ability to promote relaxation without causing drowsiness. L-Theanine increases alpha brain wave activity, which is associated with a state of calm alertness and creativity. Taken in the evening, it facilitates the transition to a state of calm, reduces stress and improves the quality of sleep without causing a feeling of "foggyness" in the morning.
5-HTP (5-hydroxytryptophan)
A precursor to serotonin, which in turn is converted into melatonin. 5-HTP supplementation helps improve mood, has antidepressant effects and regulates circadian rhythm.
Valerian extract (valerian)
A herb known for its calming and sleep-inducing effects. It helps you fall asleep, but also improves the quality of your sleep, without feeling groggy in the morning.
What is the best sleep supplement?
There is no single "best" supplement - the effectiveness depends on the cause of the sleep problem. Below are recommendations tailored to your specific needs:
Do you have trouble falling asleep? Melatonin + L-theanine
Do you wake up at night and have shallow sleep? GABA + Magnesium (glycinate) + Valerian extract
Mental fatigue, stress, excess responsibilities? Ashwagandha + L-theanine + 5-HTP
Do you train in the evening and do you have an overactive nervous system? Apigenin + Magnesium + GABA
Do you work shifts or have an irregular lifestyle? Melatonin + 5-HTP + Passiflora
What vitamin am I missing if I can't sleep?
Sleep problems, difficulty falling asleep or waking up frequently at night may be the result of deficiencies of certain vitamins and minerals that play a key role in the functioning of the nervous system and the regulation of the circadian rhythm.
Vitamin B6 (pyridoxine)
Participates in the production of serotonin and melatonin - two neurotransmitters responsible for sleep and well-being. Its deficiency can result in anxiety, tension and insomnia.
Vitamin D3
Influences the regulation of the circadian cycle, brain functions and sleep quality. Its low level is often associated with insomnia, especially in the autumn and winter.
Vitamin B12 (cobalamin)
Plays a role in regulating the circadian rhythm, and its deficiency can lead to fatigue, daytime sleepiness and problems falling asleep at night.
Vitamin C
Helps reduce the level of cortisol (stress hormone), which, in excess, can make it difficult to fall asleep and worsen the quality of sleep.
What minerals are missing in insomnia?
In addition to the previously mentioned vitamins, it is also worth paying attention to deficiencies minerals that very often accompany sleep disorders:
Magnesium (especially magnesium glycinate or taurate)
Necessary for proper nerve conduction and muscle relaxation. Its deficiency is one of the most common causes of problems with falling asleep, tension and restlessness at night.
Zinc
Supports the production of melatonin and has a stabilizing effect on the nervous system.
Iron
Iron deficiency can disrupt the functioning of the nervous system, leading to the so-called "restless legs" and insomnia.
Do sleep supplements really work?
Yes - provided they are well-matched to the cause of the sleep problem.
Sleep supplements are not a "magic pill", but an effective support for the body's physiology.
