L-Glutamine, an amino acid present in various cells in the body, exerts diverse effects. It serves as a precursor for the synthesis of glutamate and plays a role in the production of glutathione, which is formed from glutamic acid, cysteine, and glycine. Additionally, L-Glutamine is utilized by various cells for energy production, particularly muscle cells and intestinal mucosa cells. While the body can synthesize L-Glutamine under normal conditions, increased demand or insufficient endogenous production may necessitate dietary or supplemental intake. Notably, L-Glutamine is primarily synthesized in the muscles, where its concentration is highest. Increased demand for L-Glutamine may arise during periods of heightened energy requirements, such as during physical exertion or recovery from stress or injury. Conversely, decreased production may occur during stressful situations like intense physical activity or infections.
