What Is L-Glutamine?

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

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

L-Glutamine Benefits

• Supports healthy muscle mass
• Helps maintain energy levels under heavy stress
• Helps maintain optimal immune function & gut health

Glutamine can be found circulating in the blood, as well as stored in the skeletal muscles and liver, in concentrations ranging from 10- to 100-fold higher than any other amino acid.

Glutamine is utilized in a number of vital functions, including protein synthesis and production of the nucleotide units that make up DNA and RNA. Because of its importance in many cellular functions, glutamine is consumed at especially high rates during activities involving intense exercise. It is an important energy source for cells lining the gut and immune cells and critical for healthy gut and immune function. It is also a precursor of the brain neurotransmitter glutamate.

The function of glutamine in stimulating glycogen synthase, the enzyme that controls the synthesis and storage of glycogen fuel in muscles and liver, may provide a mechanism by which glutamine supplements promote enhanced fuel stores.

People who engage in heavy exercise can affect their glutamine levels, causing stress to their body and immune systems. Supplementing with glutamine can be important to a serious athlete, someone challenged with muscle loss or someone who wants to help maintain optimal immune function and energy level under heavy stress.

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