Glutamine is an amino acid. During intense training, your muscle L-Glutamine levels drop sharply. This, in turn decreases strength, stamina and recovery. Research demonstrates that following a rigorous workout, it may take up to six days for L-Glutamine levels to return to normal without supplementation. Without adequate levels of L-Glutamine, it is impossible for protein synthesis to occur.
L-Glutamine also increases cell volumization immediately. Volumized muscle cells appear larger, get a better pump and assist in protein synthesis. In fact, L-Glutamine helps muscle cells to utilize both protein and carbohydrates. L-Glutamine also acts as a powerful ammonia scavenger. Ammonia is a highly toxic substance to muscle cells.
Finally, L-Glutamine increases the body's ability to secrete (HGH). HGH assists in metabolising body fat and helos to support new muscle tissue growth. Research demonstrates that the muscles can benefit from a minium of 2 to 5 additional grams of L-Glutamine daily.
