Glutamine can be found circulating in the blood, as well as stored in skeletal muscle and liver, in concentrations ranging from 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. Because of its importance in many cellular functions, glutamine is consumed at particularly high rates during activities involving intense exercise. It is an important source of energy for the cells that line the gut and immune cells and critical for healthy gut and immune function. It is also a precursor to the brain neurotransmitter glutamate.
The function of glutamine in stimulating glycogen synthase, the enzyme that controls the synthesis and accumulation of glycogen fuel in muscle and liver, may provide a mechanism by which glutamine supplements promote increased fuel reserves.
People who exercise intensely can affect their glutamine levels, causing stress on their body and immune system. Supplementing with glutamine may be important for a serious athlete, someone struggling with muscle loss, or someone who wants to help maintain optimal immune function and energy levels under severe stress.
Studies indicate that glutamine supplementation can effectively increase glutamine concentrations in circulation and muscle tissue, promote a healthy inflammatory response, and support antioxidant defenses to maintain muscle health.
