Life Extension, L-Glutamine, 500 mg, 100 vegetarian capsules

Glutamine is an amino acid that serves as a building block for proteins. It is also an important fuel for immune cells, promoting optimal immune function.

What is L-Glutamine?

Glutamine supplements are often associated with serious athletes, but it can be beneficial for anyone who wants to maintain not only muscle health but also immune and gut health.

Glutamine is the most abundant free amino acid in the body.

Benefits of L-Glutamine

• Promotes healthy muscle mass
• Helps maintain energy levels under heavy stress
• Promotes the maintenance of optimal immune function and intestinal health

Glutamine circulates in the blood and is stored in skeletal muscle and liver at concentrations 10 to 100 times higher than any other amino acid.

Glutamine is used in a number of vital functions, including protein synthesis and the production of the nucleotide units that make up DNA and RNA. Due to its importance in many cellular functions, glutamine is particularly commonly consumed during activities that involve intense physical activity. It is an important source of energy for cells lining the gut and immune cells, and is critical for healthy gut and immune function. Glutamine is also a precursor to the neurotransmitter glutamate in the brain.

Glutamine's function in stimulating glycogen synthase, the enzyme that controls the synthesis and storage of glycogen for energy in muscles and liver, may provide a mechanism by which glutamine supplements promote improved energy stores.

People who exercise a lot can affect their glutamine levels, putting a strain on their body and immune system. Supplementing with glutamine can be important for ambitious athletes, people who suffer from muscle wasting, or who want to help maintain optimal immune function and energy levels under high stress.

Studies indicate that supplementing with glutamine can effectively increase glutamine concentrations in the blood and muscle tissue, promote a healthy inflammatory response, and support antioxidant defenses to maintain muscle health.
