Natural Factors Micronized L-Glutamine is an athletic support supplement used to restore the body’s glutamine levels after intense workouts and physical stress. Supplementation with L-glutamine enhances muscle tissue repair after heavy physical exertion, helping to accelerate post-exercise recovery and improve energy levels. L-glutamine also supports immunity and digestive system health, and has been shown to strengthen the intestinal barrier to protect it against exercise-induced intestinal permeability.

Glutamine is an amino acid found throughout the body, especially in the muscles, gastrointestinal tract, brain, and liver cells. Strenuous physical activity depletes the body’s glutamine levels, leaving the muscle and immune system cells more vulnerable to stress. Although L-glutamine can be made by the body and is found in many high-protein foods, it is most effective when taken as a free-form amino acid.

Micronized L-Glutamine is a pharmaceutical-grade, free-form amino acid made through a natural fermentation process. It uses micronization technology to minimize the particle size, making glutamine easier for the body to break down and absorb. This vegan-friendly 100% glutamine powder provides 5 g of micronized L-glutamine per serving.
