L-Glutamine Powder

L-Glutamine powder, supplied by Douglas Laboratories®, provides 4 grams of pure L-glutamine (U.S.P.) per teaspoon.


The amino acid glutamine plays a key role in the metabolism, structure, and function of the entire gastro- intestinal (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. Many clinical studies support the fact that dietary/endogenous glutamine is crucial in maintaining normal function of the entire gastrointestinal tract, including the liver & pancreas.


L-Glutamine powder may be a useful dietary supplement for individuals wishing to support their gastrointestinal system.
