Is it true L-glutamine is more for the small intestine?

I have never heard there was a distinction in the benefits. I guess I always thought statements like this one to be true for any intestinal issue. If this is NOT the case, maybe someone with more experience will chime in?

What is Glutamine?

Glutamine is the most abundant amino acid in the body and is involved in more metabolic processes than any other amino acid. When the body does not have a readily available source of glucose, the body converts glutamine into glucose. Glutamine serves as a source of fuel for the cells lining the intestines, and without it, these cells may waste away. It is also important for immune function, as it is important for the function of white blood cells. In animal research, glutamine has shown anti-inflammatory effects. Glutamine is found naturally in high-protein foods such as meat, fish, beans, and dairy products.

The proven roles of glutamine include:

promoting gut mucosal integrity by acting as an energy source and preventing bacterial translocation;


providing a major fuel source for cells of the immune system; and,
improving nitrogen balance in times of stress.
