L-GLUTAMINE – MASTER PROTEIN BUILDER L-Glutamine is an amino acid that may aid in muscle recovery, energy repletion, protein synthesis, muscle cell hydration, strengthening the immune system and helping combat illness. L-Glutamine is required by everybody that prioritises general well being and is essential for all serious athletes. This non-essential amino acid (building blocks of protein) is found in our muscles. L-Glutamine delivers protein to where it is needed most, helping the body create important nutrients, such as glutathione, glucosamine and vitamin B3. It may play an important role in helping to combat anxiety, addictions and stress, elevate energy levels in the brain, increase mental alertness, aid in surgical recovery and may positively support liver disease.
