The key to night recovery

  • Ingredient combination designed for before sleep
  • Boosts recovery.
  • Newest formula. 

During sleep our body completes important cognitive and physiological functions, more so in the case of athletes. Night rest is as relevant as any training session because during sleep the muscles grow, assimilate training stimuli and produce the adaptations you seek in every repetition and series you do in the gym.

Today’s hectic lifestyle, shift work, the use of electronic gadgets and, ultimately, any interference in the sleep-wake cycles, can alter night sleep and have a negative impact in your results.

SleepinG disorders have been associated with endocrine disruption, lower cognitive abilities and changes in the metabolic function, as a slower glucose regulation.

It is not unusual that athletes, especially when they do intense training, have problems to rest and that their performance, training capacity on even their health may be affected.

In Weider we are so focused in helping you reach your goals that we have designed an innovative product to help you rest and perform at your maximum potential.

Key ingredients in Weider Premium Night X:

  • Gamma-Aminobutyric Acid: neurotransmitter also known GABA that favors relaxation. It is used to favor sleep and promote an optimal natural production of growth hormone.
  • KSM66: highest concentration and purity Ashwagandha root. Adaptogen that aids the body to adapt to trainings and contributes to the feeling of wellness. In addition, it may modulate the activity of GABA receptors.
  • L-Glycine: non-essential amino acid that works as a neurotransmitter and favors relaxation and the subjective sensation of having a good rest.
  • L-Tryptophan and 5-Hidroxitriptophan: amino acid that, once in the brain, favor the natural production of serotonin, substance linked to the feeling of happiness.
  • Resistant Dextrin: Carbs ease the entrance of tryptophan in the brain.  Resistant dextrin is absorbed slowly without producing blood glucose peaks.
  • Magnesium: essential mineral for the functioning of the nervous system. The right intake of magnesium guarantees healthy sleep.
  • Choline: aids in the adequate fat metabolism.
  • L-Theanine: amino acid contained in tea with the capacity to favor feeling wellbeing and peace.
  • Zinc: boosts hormonal and immune systems and testosterone production.
  • Vitamin B5: involved in the metabolism of fat acids, amino acids, steroid hormones, etc.
