Glutamine is a non-essential amino acid that the human body can produce on its own. Besides helping to regenerate and build muscle, it is also known for its beneficial impact on the immune system. Since glutamine accounts for up to 60% of the amino acids in muscle cells, it is recommended to take it in regular and high-intensity workouts. It is also perfect nutritional supplement for weight loss.

Sources of glutamine

As an amino acid, glutamine is a part of protein-rich food. It is found in meat, dairy products, eggs, legumes, white rice or tofu. It is a common ingredient of nutritional supplements for athletes, especially for its anti-catabolic effects. It prevents the muscle breakdown and promotes function of muscle cells.


Why is glutamine necessary for the body?

Glutamine is the most abundant amino acid in the body. It is found in muscles, brain, blood, liver and lungs. Although the body can produce it itself, there are times when it is necessary to supplement glutamine.


It is necessary to increase glutamine intake for those who consume little meat and dairy products or perform intensive workouts. Although, glutamine does not directly contribute to muscle mass growth, it will support muscle regeneration after a demanding workout or during a stressful period, leading to faster recovery and thus support muscle growth. Its role is to normalize growth hormone, promote glucose utilization after training, promote muscle hydration and suppress lactic acid in the muscles, thereby relieving muscle stiffness.


Glutamine is a suitable nutritional supplement for intensive workouts as well as to boost immunity. A demanding exercise leads to a glutamine deficit, resulting in a deterioration of white blood cell function, and this leads to a weak immunity. You can take it alone or in combination with your favorite protein shake.


Glutamine and its use

The recommended dosage of glutamine is about 5 grams 3 to 4 times a day.

How does glutamine synthetase work?

Glutamine is the most abundant amino acid in the body. It is produced in the muscles and distributed through the blood to the organs. It is a necessary element for both protein and glucose production in the body. During stress, glutamine promotes the immune system and bowel function. However, muscle mass loss may occur if the body uses more glutamine than the muscles themselves due to stress. This process occurs in people suffering from AIDS.


Futher uses of glutamine

Glutamine is also used as a nutritional supplement in medicine. It is a convenient means of eliminating the side effects of cancer treatment, nerve, muscle, joint, and digestive tract pain caused by the disease. It is suitable as a nutritional supplement after bone marrow transplantation. People suffering from AIDS take glutamine to prevent weight and muscle loss. Positive impact of glutamine has also been observed in the treatment of depression, moodiness, irritability, anxiety or insomnia.
