The Function of L-Glutamine Under Physiological Stress

L-Glutamine is the most abundant free amino acid in human muscle tissue. During strenuous physical exertion, muscle stores can drop sharply, adversely affecting both immune system cells and intestinal epithelial tissue.

Intestinal Epithelial Integrity and Nutrient Absorption

Enterocytes in the intestinal mucosa consume glutamine as their primary energy source. When availability decreases, the protein structures known as tight junctions that hold cells together weaken, which can lead to localized inflammation and reduced nutrient absorption.

Importance for Long-Term Performance

Methodical intake of pure L-Glutamine prevents the body from breaking down muscle protein to meet immune system demands. The preparation is best mixed with lukewarm water and consumed immediately after training to accelerate the restoration of cellular balance.
