What is it?

Glutamine is a conditionally essential amino acid and the most abundant amino acid in the human body. Glutamine can be found inherently in whey protein, wheat, corn, barley, peanuts, soybeans, and milk.

What does it do?
Glutamine is important for several bodily functions, and it is one of the building blocks for protein. Under conditions of stress, such as strenuous exercise or during illness, more glutamine may be needed to help restore glutamine levels in the body. Glutamine is also a major fuel source for the GI tract and helps support immune cells in the body for defense.
