Glutamine is the primary fuel for our immune system. After it is synthesized in our skeletal muscle, it is discharged into immune cells throughout the body. However, during an intense workout or endurance training session, L-Glutamine is depleted, ultimately leading to a temporarily weakened immune system. Supplementing can insure that adequate levels of the amino acid are available for the immune system to properly function.
Glutamine makes up approximately 60% of skeletal muscle tissue, making it the most abundant amino acid in the human body. The most widely-known benefit of L-Glutamine is its ability to help muscles repair and recover by increasing the rate of Muscle Protein Synthesis.
