L-Glutamine is an amino acid that can be found throughout the body, especially in the brain, gastrointestinal tract, muscles, and liver cells.
After periods of physical stress, L-glutamine helps support a healthy immune system and digestive system, and helps restore depleted glutamine levels in the blood and muscle. Glutamine is the most abundant amino acid in skeletal muscle and plasma and is known to be an important nutrient for cell proliferation, survival, and repair; defending the body against inflammation and infection; and helping the body recover from illness or stress.
More glutamine is used during periods of prolonged or heavy exercise, trauma, inflammation, immune system dysfunction, and some illnesses. These states may result in a glutamine deficiency, leading to impaired immune response and increased risk of infection. 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.
Natural Factors L-Glutamine Free Form Amino Acid is natural muscle food contained within vegetarian capsules. This is especially beneficial to vegetarians, vegans, or people following restricted diets who may not get enough L-glutamine through food sources alone. Glutamine supplementation is ideal for athletes who want to prevent problems associated with intensive training, and for anyone who would like to recover faster from over-training.
