In the body, glutamine functions as a major nitrogen transporter and is critical for the maintenance of healthy nitrogen balance.* Glutamine also acts as the primary fuel for the rapidly growing cells of the immune system and GI tract.* NOW® L-Glutamine Powder is a pure, free-form, non-essential amino acid and is the highest grade available.
