What the research says about L-glutamine
Peer-reviewed studies and reviews on the amino acid L-glutamine - shared for education, not as claims about this finished product. AOR L-Glutamine's claims are the statements authorized under its Natural Health Product licence, NPN 80005719.
Fuel for the gut lining
Reviews describe L-glutamine as a primary energy substrate for enterocytes that supports the structure and function of the intestinal mucosa.
ReviewGlutamine and the gut microbiota
A review summarized glutamine's role in the interaction between the gut microbiota and intestinal health.
ReviewConditionally essential under stress
Glutamine demand rises during catabolic stress, when intestinal cells draw heavily on it as fuel.
ReviewSupports tight-junction integrity
Experimental work describes glutamine's role in protecting epithelial tight junctions that form the intestinal barrier.
Lab & reviewBarrier function under stress
Reviews link adequate glutamine to maintenance of intestinal permeability during physiological stress.
ReviewMucosal protection mechanisms
Glutamine is described as supporting mucosal growth and repair pathways in the gastrointestinal tract.
ReviewFuel for immune cells
Lymphocytes and macrophages consume glutamine at high rates; a classic review explains why it matters to immune-cell function.
ReviewImmune function & supplementation
A comprehensive review covered glutamine metabolism, immune function and clinical translation.
ReviewAfter prolonged exercise
An early trial examined oral glutamine and post-exercise immune-related outcomes in athletes after exhaustive exercise.
Human studyStrength recovery after eccentric exercise
A controlled trial reported faster recovery of muscle strength and reduced soreness with oral L-glutamine after eccentric knee-extension exercise.
Human RCTAnti-fatigue role in sport
A review discussed glutamine as an anti-fatigue amino acid in sports-nutrition contexts.
ReviewReleased from muscle under stress
Glutamine is stored in skeletal muscle and mobilized during physical stress, linking muscle reserves to recovery.
ReviewNitrogen transport
Glutamine is a major carrier of nitrogen and carbon between tissues, central to whole-body amino-acid metabolism.
ReviewMost abundant free amino acid
Reviews note glutamine is the most abundant free amino acid in blood and the body's free amino-acid pool.
ReviewNon-nutritive signalling roles
Beyond fuel, glutamine has signalling and regulatory effects on cell metabolism described in the literature.
ReviewGlutathione precursor support
Glutamine contributes to glutathione synthesis, part of the body's antioxidant defence system.
ReviewRedox balance under stress
Reviews link glutamine's antioxidant role - via glutathione - to redox balance during the oxidative stress of critical illness.
ReviewHeat-shock & protective pathways
Glutamine has been linked to expression of protective heat-shock proteins in stressed cells.
Animal studyStudied in clinical nutrition

ReviewWhat glutamine is
L-glutamine is a non-essential amino acid that becomes conditionally essential when the body's needs outpace what it can make.
ReviewWhere it's stored
Skeletal muscle is the body's main glutamine reservoir, supplying other tissues on demand.
ReviewWhy supplement
Reviews note that dietary or supplemental glutamine can help meet elevated demand during physical stress.
