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 Capsules' claims are the statements authorized under its Natural Health Product licence, NPN 80014988.
Lower gut permeability during exercise in the heat
A controlled trial found acute oral glutamine reduced a lactulose:rhamnose marker of intestinal permeability after running in the heat, in a dose-dependent pattern.
Human RCTSupports the intestinal lining under inflammatory stress
In an experimental colitis model, glutamine reduced bleeding and diarrhea scores and increased protective heat-shock proteins in the colon lining.
Animal & cell studyOne of several amino acids that reinforce the gut barrier
A review of conditionally essential amino acids in intestinal disease lists glutamine, alongside glycine and aspartate, as contributing to intestinal barrier integrity and healthy gut microbiota composition.
ReviewStudied as part of post-exercise immune recovery
A review of nutritional strategies for exercise-induced immune changes in endurance athletes discusses glutamine among several nutrients studied for supporting immune status after heavy training.
ReviewOne of several nutrients studied around marathon racing
A review of strategies to support runners' immune function during the post-race recovery window examined glutamine alongside vitamin C and bovine colostrum.
ReviewA closer look across 8 glutamine trials in athletes
A systematic review and meta-analysis pooling supplement trials in athletes included 8 glutamine studies among carbohydrate and vitamin C trials, evaluating effects on post-exercise immune markers.
Meta-analysisBiochemical mechanisms behind exercise recovery
A narrative review describes how glutamine contributes to redox balance, energy sensing, anabolic signaling and intestinal barrier integrity during exercise-induced stress.
ReviewLower muscle-damage markers in athletes
A crossover trial in professional basketball players supplementing 6 g/day of glutamine reported lower blood markers of muscle damage (creatine kinase, myoglobin) than placebo.
Human RCTFaster strength recovery after eccentric exercise
A double-blind crossover trial found oral L-glutamine sped recovery of knee-extensor peak torque and reduced soreness ratings for 72 hours after eccentric exercise.
Human RCTA recognized role in modern ICU nutrition guidance
A 2026 review of evidence-based ICU nutrition strategies notes that, while routine intravenous glutamine is no longer recommended, enteral glutamine retains a specific role in major burn injury care.
ReviewA proposed mechanism in sepsis-related immune suppression
A laboratory study found glutamine restored macrophage bacterial clearance and improved survival in a sepsis model by supporting mitochondrial calcium-signaling pathways.
Preclinical studyTracking catabolism in major burn injury
A retrospective study of major burn patients (>=20% body surface area) used the urea-to-creatinine ratio to track the intense protein catabolism - the same muscle-breakdown stress response that depletes the body's glutamine reserves - through the first 30 days of care.
Clinical studyWell tolerated in a placebo-controlled trial in older adults
A double-blind, placebo-controlled trial giving older adults 12.4 g/day of oral glutamine for 60 days found no significant adverse changes in blood chemistry, inflammatory markers, or kidney and liver values.
Human RCTWell tolerated in a pediatric clinical trial
A randomized pilot trial of oral glutamine for vincristine-related nerve symptoms in children and adolescents with cancer reported the supplement was well tolerated, with no significant difference in side effects versus placebo.
Human RCTA safety track record across dozens of clinical studies
A review of glutamine in oncology summarized 36 clinical studies over two decades, concluding that appropriate oral or intravenous glutamine supplementation is generally safe across the patient groups studied.
ReviewHow glutamine compares with whole protein for muscle
A review of protein and amino-acid supplementation in sport found milk-protein supplements consistently support muscle protein synthesis and recovery, while single amino acids like glutamine, BCAAs or leucine show more equivocal results.
ReviewCompared against creatine, caffeine and flavonoids
A review of non-carbohydrate dietary factors for post-exercise glycogen recovery compared glutamine with creatine, caffeine and flavonoids, finding evidence for each - including glutamine - still limited and inconclusive.
ReviewTested alongside creatine, arginine and taurine
A crossover trial compared a multi-ingredient pre-workout containing glutamine, creatine, arginine and taurine against creatine alone and placebo, finding the combination produced greater improvements in fatigue markers after resistance exercise.
Human RCTHow glutamine crosses into cells
A molecular-dynamics study modeled how the ASCT2 transporter shuttles glutamine into cells, describing its role as a nitrogen and carbon source for cellular biosynthesis, including in the gut where dietary amino acids are absorbed.
Computational studyThe enzyme that puts glutamine to work
A mouse study of the enzyme glutaminase 1, which converts glutamine to glutamate for cellular energy metabolism, illustrates why glutamine is classified as a conditionally essential amino acid.
Animal studyInvestigated for its antioxidant and anti-inflammatory biochemistry
A systematic review of glutamine, described as a conditionally essential amino acid, found several trials reporting reduced inflammatory or oxidative-stress markers (CRP, MDA), though not consistently across every study.
Systematic reviewHow the body absorbs and clears oral glutamine
A population pharmacokinetic study found oral L-glutamine is absorbed and eliminated on a one-compartment model, with no significant drug accumulation across ascending doses taken with or without food.
Human PK studyMeasuring glutamine levels after a dose
A pharmacokinetic study in healthy adults developed a validated method to track plasma glutamine after oral 2 g and 4 g doses, supporting dose-comparison research.
Human PK studyRethinking the right research dose
A review argues that clinical glutamine doses for intestinal support should be modeled on the amount the small intestine actually metabolizes daily (around 30 g), rather than typical dietary intake levels.
