Natural Factors 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.

L-Glutamine is a pharmaceutical-grade, free-form amino acid made through a natural fermentation process. It is available in two strengths in vegetarian capsule form, to be taken multiple times per day for the most effective absorption and use by the muscles. This is a fantastic choice for vegetarians, vegans, and anyone who is highly active and wants to recover faster after each workout.
