Glutamine

Glutamine is the most abundant amino acid in the body. Amino acids are building blocks of protein, and protein is the building block of muscles. Your body is making enough glutamine it needs. But, sometimes, when you go to the gym or when you are an athlete, the body might be needing more glutamine than it can produce. Glutamine is responsible for metabolism of protein, cell and energy regeneration. This makes you able to cope with the energy and protein demands of your activity, either work-out or athletic performance.
