An important amino acid, L-glutamine has many benefits for the body and muscle building.
What is it? How does it work?
Glutamine is classified as an amino acid, which are the building blocks of protein. However, it is not considered essential, as the body is able to produce it naturally. Still, glutamine has numerous benefits for the body. Firstly, it is helpful in aiding the body's immune system, as it is an important fuel for immune cells like white blood cells (1). It also helps improve your intestinal health as it acts as an energy source for intestinal cells, maintaining the barrier between the insides of your intestines and the rest of your body, protecting against a leaky gut and preventing harmful bacteria or toxins from leaking into the rest of your body (1). Glutamine has not shown to be effective in increasing muscle strength or gains; however, it has shown to improve strength recovery and alleviate muscle soreness.
My opinion: Is it worth the money?
As seen from above, glutamine does have a lot of benefits on the body. However, not only is it usually abundant in protein-rich foods and protein supplements, but it can also be produced naturally by the body. That said, if you are already consuming enough protein, it is unnecessary to spend extra money supplementing glutamine to your diet. If you still feel the need to supplement your diet with glutamine, below are some recommendations.
