Drugstore articles: L-Glutamine Video Guide

At 20%, L-glutamine is the most strongly represented amino acid in blood plasma. The highest concentration is found in the small intestine and muscles. L-glutamine is responsible for a number of synthesis reactions in the body. The amino acid provides nitrogen and forms amino sugars, nucleotides and purines. L-Glutamine is particularly important for strength athletes and competitive athletes, as it promotes muscle growth. However, for this anabolic effect a high dose of L-glutamine must be added

L-glutamine is classified as a non-essential amino acid. The body can produce a certain proportion of this amino acid itself. Nevertheless, a sufficient supply of glutamine via the diet is indispensable in view of the manifold functions in the human body. Especially in times of strong physical activity and stress, the body needs a lot of this amino acid in order to be able to perform processes such as

– supply of cells of immune system with energy- muscle build- muscle mass maintained- influence on concentration and memory- regulation of blood sugar level- water storage in body cells- increase of cell volume- supply of muscle cells and gastrointestinal tract with energy- transmission of nerve stimulus- regulation of base acid balance- support of immune system

Need for L-Glutamine

As a non-essential amino acid, L-glutamine can partly be produced by the body itself. However, the consumption of L-glutamine increases strongly during stress or injuries, so that sufficient amino acid must be supplied through the diet. In particular, people with recovery disorders or infections as well as competitive athletes have an increased need and must supply the body with more glutamine

Cocoa has the highest glutamine content of all foods at 4.8 g per 100 g. Foods such as dairy products, wheat products, soya products, smoked or raw meat, smoked or raw salmon, eggs and walnuts are recommended as suppliers of amino acids as part of the daily diet. However, L-glutamine is very sensitive to heat, so that the amino acid can easily be destroyed during the preparation of the food

L-glutamine deficiency can occur in the body if there are metabolic disorders, serious infections, operations or extensive injuries. Following major surgical procedures or after prolonged infection, a glutamine-rich diet is recommended to support the healing process and prevent complications

In the meantime, studies have shown that the daily intake of L-glutamine has a noticeable improvement in patients with resorption disorders such as Crohn’s disease. The amino acid is also used in the treatment of tumor diseases to increase immune competence, achieve accelerated regeneration after bone marrow transplantation and minimize the risks of chemotherapy and radiation therapy. Glutamine can also be helpful in the treatment of impotence, alcoholism and senility. In less drastic conditions, L-glutamine can positively influence individual body processes to bring about faster healing. L-glutamine supports kidney function, liver function, the transmission of stimuli and the energy supply of digestive organs and muscles
