L-Glutamine

Cellular recovery and metabolic support

L-glutamine is a conditionally essential amino acid that plays an important role in cellular metabolism and tissue maintenance. It is one of the most abundant amino acids in the body and serves as a key fuel source for rapidly dividing cells, including intestinal epithelial cells and immune cells.

In muscle tissue, glutamine participates in nitrogen transport and amino acid metabolism, processes that are involved in muscle protein turnover and recovery following physical activity. Because of this role in cellular metabolism, glutamine is commonly studied in relation to exercise, recovery, and metabolic support.

Glutamine also contributes to maintaining the integrity of the intestinal barrier, as intestinal cells rely on it as an energy source. For this reason, it is often included in nutritional strategies aimed at supporting both digestive health and overall physiological resilience (M. I. Lindinger, 2020).
