Glutamine is a non-essential protein amino acid that accounts for up to 60% of the amino acid content of muscle cells. In stressful situations such as physical stress, stress, illness there is an increased release of glutamine from muscle cells, the so-called. to catabolism. Although the body can "produce" glutamine from other amino acids (valine, isoleucine, leucine, etc. Glutamic), this amount is not sufficient and must be supplied from the outside. High levels of physical stress and the concomitant long-term lack of this amino acid in the body result in loss of muscle mass, fatigue, an increase in the time required for regeneration, and a deterioration of the body's immune response.
