A key amino acid for intestinal health and immune function, providing 4,000 mg of pure L-glutamine per serving.‡
The amino acid glutamine plays a key role in the metabolism, structure, and function of the entire gastrointestinal (GI) tract and its extensive immune system. Glutamine is the most abundant amino acid found in
blood, and is a vehicle for nitrogen transport. In muscle, lung and other tissues, glutamine is formed from
glutamic acid and ammonia through amino acid breakdown. The GI tract, liver, and immune system use
glutamine for the synthesis of nucleotides, proteins, and amino sugars. Glutamine also carries potentially toxic
ammonia to the kidneys for excretion, which helps maintain normal acid-base balance.
