What is Glutamine?

L-glutamine, or simply glutamine, is a nonessential amino acid that plays a vital role in recovery and maintaining muscle mass. During times of extreme stress, illness, or injury, glutamine can become an important amino acid to aid in your recovery.

What Does Glutamine Do?

Glutamine is involved in a variety of functions in the body, including protein synthesis, which is essential for growing and repairing muscle. Glutamine also boosts immunity, supports digestive health, and aids in cellular metabolism.

Why Supplement With Glutamine?

If you are deficient in glutamine, your body will not function properly. Glutamine is the most abundant and versatile amino acid in the body, and it makes up approximately  60% of skeletal muscle tissue. Glutamine is the basic building block for protein synthesis, muscle repair, and muscle growth, as well as being a fuel source for your immune cells, especially lymphocytes and macrophages. As for digestive health, glutamine maintains the integrity of your intestinal lining, helping to keep your gut healthy and happy. Lastly, glutamine also transports nitrogen, which aids in getting your cells energy.

Glutamine is well-tolerated and has very few if any side effects for the general population. So, if you’re lifting heavy, running fast, or otherwise working out hard, your body needs more glutamine for muscle growth, muscle repair, and renewed energy. As for additional benefits, while studies are mixed about the efficacy of glutamine for weight loss, a meta-analysis of the literature has shown glutamine supplementation has helped to reduce weight significantly.[1] Other studies have shown Glutamine to help with peak contractions, better recovery times, and less perceived soreness.[2]
