Intensive training is a challenge for both the body and mind. On the one hand, it brings health benefits, but on the other, it can lead to sleep problems. Night-time regeneration is crucial for athletes, as the body rebuilds muscles and the nervous system during sleep. Modern science offers solutions that help improve sleep quality, such as SELANK and OKTAPEPTYD – NL-SELANK™.
Why do intense workouts make it difficult to sleep?
Many people struggle to fall asleep after a demanding workout. This problem stems from several factors:
- Elevated cortisol levels: Stress hormones such as cortisol are naturally elevated during exercise, but excess amounts can interfere with the body's ability to wind down in the evening.
- Physical and mental fatigue: Overtraining affects the nervous system, which can make it difficult to relax even after the day is over.
- Circadian rhythm disorders: Physical activity in the evening disrupts the natural sleep rhythm, making it difficult to fall asleep and shortening the regenerative phases of deep sleep.
That is why it is so important to support the body with appropriate supplements that alleviate these negative effects.
SELANK and OKTAPEPTYD – NL-SELANK™ peptides
Peptides are innovative substances that can significantly support recovery after exercise and improve sleep quality. SELANK and OKTAPEPTYD – NL-SELANK™ stand out from other preparations due to their unique properties.
- SELANK: This peptide is known for its anti-anxiety effects. It reduces stress, calms the nervous system and promotes peaceful sleep. It also supports concentration and mood, which is beneficial for athletes.
- OKTAPEPTYD – NL-SELANK™: This is a more advanced formula that helps regulate sleep patterns and facilitates the transition into deep sleep phases. Regular use of this preparation can help combat chronic insomnia.
- Relieving tension after training: Both peptides support the regeneration of the nervous system, which is extremely important after intense training sessions.
List of natural supplements that promote sleep
Peptides are not the only substances that can help improve sleep quality. There are also natural supplements available on the market that promote regeneration. It is worth paying attention to:
- Magnesium and vitamin B6: These ingredients support the functioning of the nervous system, help you relax and reduce muscle tension.
- Melatonin: A natural hormone that regulates the circadian rhythm, particularly effective for difficulty falling asleep.
- Ashwagandha: An adaptogen that reduces cortisol levels and helps calm the body.
- L-theanine: An amino acid known for its calming effect, often used before bedtime.
Incorporating these supplements into your daily routine can significantly improve night-time recovery.

How to use SELANK and NL-SELANK™?
SELANK and NL-SELANK™ peptides are increasingly chosen by athletes due to their versatile effects. However, their effectiveness depends on proper use.
- Consultation with a specialist: It is always a good idea to consult a doctor or dietitian about supplementation in order to select the appropriate doses.
- Regularity: The best results are achieved with regular use of peptides in accordance with the manufacturer's recommendations.
- Avoiding excessive strain: Combining supplements with properly planned rest and regeneration significantly increases their effectiveness.
Benefits of improving sleep quality
Sleep is the time when the body regenerates. Improving sleep quality translates into:
- faster muscle recovery after exercise,
- reduced risk of injury,
