I feel it aids in gut health, recovery, helps keep my immune system healthy, plenty of bcaa's in chicken, beef, fish, eggs..not to mention all the artificial sweeteners.
Athletes
Athletes who train for endurance events (like marathons) may reduce the amount of glutamine in their bodies. It is common for them to catch a cold after an athletic event. Some experts think that may be because of the role glutamine plays in the immune system. For this select group of athletes, one study showed that taking glutamine supplements resulted in fewer infections. The same is not true, however, for exercisers who work out at a moderate intensity.
Inflammatory bowel disease (IBD)
Glutamine helps protect the lining of the gastrointestinal tract known as the mucosa. For that reason, some researchers believe that people who have IBD (ulcerative colitis and Crohn disease) may not have enough glutamine. However, two clinical trials found that taking glutamine supplements did not improve symptoms of Crohn disease.
As you can see glutamine is a waste of money for a bodybuilder and you taking it for gut health would be like a person with no pain taking a painkiller.
