L-Glutamine is an amino acid used by sports people to aid them in achieving their nutritional and performance goals. L-Glutamine is one of the most valuable amino acids to supplement with. L-Glutamine stores are largely depleted due to extreme exercise so it is often supplemented in the diet when partaking in intensive training or physical exercise. The body is capable of manufacturing L-Glutamine on its own, but in most cases can never manufacture enough to fill the daily needs of sports people, therefore protein rich foods and L-Glutamine supplementation should be included in a nutritional diet.
If you're working hard in the gym each day, there's no question that you'll want to be taking care of your body during training. Each time you lift weight, a large amount of stress is placed on the body. Unless something is done to help your body recover during training, fatigue will always be there to ruin your training.
Additionally, longer recovery time means longer time to reach your goals. The body can lose up to 50% of its glutamine levels during training, and if your immune system or other parts of your body become glutamine-deficient, the muscles' glutamine stores are first to be robbed, creating the risk for catabolism. Help your body progress, not go backwards.
Often overlooked as a simple amino acid, Glutamine is one of the best anti-catabolic ingredients around, so start sending in those reinforcements and supporting your body's battle in the gym or the training field.
