BEST Pure L-Glutamine Powder - 300 grams




Product benefits:





  • Supports protein synthesis and muscle mass.


  • Improves immune function.


  • Participates in the production of BCAAs.


  • Helps regulate water distribution in the body.


  • Suitable for vegans and free of GMOs, gluten and soy.






Glutamine is a key amino acid that plays an important role in maintaining muscle mass and overall health. As an important regulator of protein synthesis and breakdown, it supports the normal structure of muscle fibers. According to research, glutamine also plays an important role in the synthesis of BCAAs (branched-chain amino acids), which are essential for muscle regeneration and growth.




Additionally, glutamine supports the immune system and improves water distribution in the body, which is beneficial for athletes and active people. It is important to mention that the supplement is safe for vegans and does not contain GMO, gluten and soy, making it suitable for various dietary needs.




Warning: Avoid use if you are pregnant, breastfeeding or have liver disease. If you are sensitive to monosodium gluconate (MSG), there is a risk of a reaction to glutamine, as the body can convert it to glutamate. When taking L-Glutamine for a long time, it is recommended to supplement with B vitamins.




Important: Do not exceed the recommended dose! Keep out of the reach of children! The supplement cannot replace a varied diet. Store in a cool, dry place (maximum 25°C) in the original packaging. After opening, store closed in the original packaging. Best before: See packaging.
