L-Glutamine - 500 mg. 60 caps

L-Glutamine 500 mg capsules, provided by Douglas
Laboratories, contain 500 mg of pure crystalline Lglutamine
(USP).
FUNCTIONS
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 and
endogenous glutamine is crucial in maintaining normal
function of the entire gastrointestinal tract, including the
liver and pancreas. Glutamine helps maintain normal
intestinal permeability, mucosal cell regeneration and
structure, especially during periods of physiological
stress.
The human intestinal tract removes as much as 12-13% of
circulating blood glutamine in addition to the glutamine
absorbed from dietary origin. Intestinal mucosal cells
need glutamine as a nitrogen donor for the biosynthesis of
a number of important compounds, including nucleotides
needed for cell division, amino sugars for building the
glycosaminoglycans of intestinal mucous, and many
amino acids that are crucial for protein synthesis.
During physiological stress, such as starvation, physical
trauma, or surgery, the intestinal tract uses very large
amounts of glutamine. This often results in a fall of blood
glutamine, and skeletal muscle is broken down to supply
more glutamine.
The immune cells of mucosa, mesentery and the liver
depend on glutamine as a key nitrogen donor and energy
source.
