L-Glutamine is used as a dietary supplement by those attempting to improve GI health, digestion, and reduce "leaky gut" and "intestinal permeability". Some clinical studies and some anecdotal evidence support this use. L-Glutamine is classified as an essential Amino Acid (it cannot be produced by the body and therefore must be consumed). If it is obtained insufficiently from food, then it must be supplemented for optimum health and to meet FDA guidelines. L-Glutamine is a building block of muscles and is essential for protein metabolism. L-glutamine has also been found to boost bicarbonate production, which buffers lactic acid produced during intense workouts, leading to decreased soreness. GUT LAB's L-Glutamine is 100% free-form and pure, which allows for maximum absorption (no competition among amino acids). GUT LAB uses a Good Manufacturing Practices (GMP) certified FDA-approved manufacturing facility in Coral Springs, Florida, and is headquartered in Jackson, Wyoming. GUT LAB's L-Glutamine is derived from vegetables and is thus vegan and vegetarian. However, the capsules are made from gelatin and thus are not. You can open the capsules and mix them into water if you are vegetarian.
