    What is glutamine? 

    Glutamine is the most abundant amino acid in the blood and muscles. It is not an essential amino acid because the body itself is capable of synthesizing it. It is mainly synthesized in the skeletal muscles. 


    Glutamine is particularly essential when the body is subjected to intense sports sessions, or when the body undergoes trauma, burns or infections. A decrease can be noted when the subject is in a state of prolonged stress (injury, sports practice, trauma, inflammation, healing). The latter is then exposed to several infections, the immune system being defective. In this case, glutamine becomes a semi-essential amino acid.


    Like other amino acids, glutamine exists in two different forms:

    1. L-glutamine

    2. and D-glutamine.

    Although they are almost identical, there is a small difference in their molecular structure. L-glutamine is the form found in foods and dietary supplements rich in glutamine. It is synthesized from glutamic acid, which is obtained by catabolism of other amino acids.


    However, some foods are truly important sources of glutamine. These include dairy products, legumes, grains, meat and fish. Consuming these foods will therefore promote the production of this amino acid. You can also consult our top 10 foods for bodybuilding.


    Glutamine has many scientifically proven roles. Don't think that athletes are the only ones concerned by taking glutamine, the positive effects on the immune system and the intestinal wall are for everyone.


    The benefits of glutamine


    1. A better recovery

    This is often the first argument we hear about taking glutamine: better recovery. This is mainly due to the ability of glutamine to improve the replenishment of muscle glycogen. Glycogen is the carbohydrate stores in the muscle cells, in other words an energy reserve for your muscles.


    Many studies have shown the impact of glutamine on the speed of replenishing muscle glycogen. This first advantage assures athletes the possibility of chaining intense training sessions.


    2. Increased protein synthesis

    Like all other amino acids, glutamine serves as a substrate for the formation of proteins. These are necessary for the functioning of the muscles. Without this amino acid, it is almost impossible to perform certain movements.


    L-glutamine participates in the development of muscle tissue by promoting protein synthesis and amplifying the action of Leucine. For cause, it has an anabolic effect. This means that it promotes an important secretion of proteins and muscle cells. 


    The anabolic effects of glutamine are not exclusively associated with its action on protein synthesis, but also with an increase in the production of natural growth hormone, and the ability to lower cortisol levels allowing for increased glycogen stores in the muscles.


    It can be noted that glutamine-rich supplements and BCAAs work together for protein synthesis and muscle mass gain.


    3. Cartilage and tendon repair

    Glutamine is responsible for the production of glucosamine. Glucosamine is involved in the cartilage and tendons of the muscles and facilitates their reconstruction. A good concentration of glutamine in the muscles ensures their solidity and resistance. Moreover, the chances of rapid recovery in case of muscular injuries are very high.


    4. Protection of the immune system

    An increase in glutamine in the muscles also reduces the risk of leucine oxidation. The formation of free radicals is therefore no longer possible, nor is the destruction of cells. The organism benefits from a better protection. On the other hand, a glutamine deficiency also leads to an imbalance in the immune system, fatigue, and can cause various infections (the intestinal wall becomes weaker).


    It should be noted that glutamine supplementation is used in the hospital environment in cases of chemotherapy or other treatments because it plays a positive role on the body.


    5. Maintenance of the integrity of the intestinal wall

    Glutamine is this amino acid that helps to correct porosity problems in the intestine. This improves the digestion process and facilitates the sorting out of this exchange wall. Glutamine plays a very important role in maintaining the integrity of the body.

    Glutamine is the best source of energy for enterocytes (cells in the small intestine) and for white blood cells.


    6. Maintenance of the acid-base balance

    To all this, we must add the importance of glutamine in maintaining the acid-base balance in the blood. It helps to fight against the acidity of the body's pH, often due to a poor diet and sustained physical activity.

    De même, elle favorise le ralentissement du vieillissement de la peau et améliore la qualité de sommeil.


    La glutamine dédiée aux sportifs ? 

    En raison de l’intensité des exercices auxquels ils se soumettent, les sportifs peuvent avoir besoin d’une supplémentation en glutamine, à ce titre nous pouvons associer différents sports : la glutamine musculation ou bien glutamine endurance. En effet, une forte activité physique provoque une importante baisse du taux de glutamine, ce qui fragilise dans une certaine mesure l’organisme. Un apport en glutamine permet donc de bénéficier d’une importante quantité d’énergie durant la séance.

    La présence en forte concentration de la glutamine dans les tissus musculaires favorise la réduction des douleurs musculaires ainsi que la récupération après des efforts physiques intenses. Il va s’en dire que glutamine et récupération vont de pair.


    Quand la prendre ? 

    La prise de glutamine est majoritairement conseillée après une séance de sport pour les différents bienfaits comme la récupération et la synthèse des protéines. 


    Certains sportifs professionnels l'utilisent avant et pendant le sport pour atténuer la fatigue constaté.
