A healthy gastrointestinal lining is essential for proper digestion, immune function, and overall health. Glutamine Plus features three key ingredients—glutamine, deglycyrrhizinated licorice (DGL), and inner aloe leaf—that are designed to support the integrity and healthy function of the gastrointestinal lining.*


  • Soothes and Supports Healthy Digestive Function*
  • Supports Intestinal Healing*
  • Helps Improves the Symptoms of “Leaky Gut”*
  • Supports Healthy Immune Function*
  • Helps Maintain Muscle and Improve Protein Metabolism*
  • May Reduce Delayed Onset Muscle Soreness*
  • Helps Reduce Sugar Cravings*

Glutamine is the preferred fuel source for the cells that line the small intestine, making it an indispensable component of any gut healing plan.* Glutamine is a “conditionally essential amino acid:” normally the body can make glutamine from other amino acids, but under stress—including emotional or physical stress, heavy exercise, or infections—glutamine becomes depleted, and has to be supplied by the diet.

Glutamine is also a central component of glutathione, the body’s most important and abundant antioxidant and detoxifier, and has been shown to enhance immune system function.1 In clinical research, glutamine has been found to reduce intestinal permeability and gut symptoms in irritable bowel syndrome as well as high-heat exercise.2,3

Deglycyrrhizinated licorice (DGL) and inner aloe leaf extract are soothing anti-inflammatory herbal remedies for the entire lining of the digestive tract. DGL and aloe both have a long history of use to heal stomach ulcers, reduce gastrointestinal inflammation, and ease heartburn symptoms.*[4,5] 

Whether you use it for digestive tract healing or to support an active lifestyle, we think you’ll love Glutamine Plus!

Glutamine Plus is a staple for our patients’ gut healing plans. We know the gastrointestinal tract is at the center of whole body well-being, and in our experience Glutamine Plus benefits nearly everyone! This simple but effective formula features potent doses of the optimized forms of glutamine, licorice and aloe:

Licorice naturally contains a compound called glycyrrhiza, which can increase blood pressure and water retention in some people. Glutamine Plus is formulated with deglycyrrhizinated licorice, which removes this potentially harmful compound for SAFE and targeted benefits.

Whole leaf aloe extract, which includes the outer latex portion of aloe leaves, is known as a strong laxative and may cause cramping. Glutamine Plus utilizes pure inner aloe leaf gel powder, which is NOT associated with these adverse effects.

Glutamine as an immunonutrient

Dietary supplementation with nutrients enhancing immune function is beneficial in patients with surgical and critical illness. Malnutrition and immune dysfunction are common features in hospitalized patients. Specific nutrients with immunological and pharmacological effects, when consumed in amounts above the daily requirement, are referred to as immune-enhancing nutrients or immunonutrients. Supplementation of immunonutrients is important especially for patients with immunodeficiency, virus or overwhelming infections accompanied by a state of malnutrition. Representative immunonutrients are arginine, omega-3 fatty acids, glutamine, nucleotides, beta-carotene, and/or branched-chain amino acids. Glutamine is the most abundant amino acid and performs multiple roles in human body. However, glutamine is depleted from muscle stores during severe metabolic stress including sepsis and major surgery. Therefore it is considered conditionally essential under these conditions. This review discusses the physiological role of glutamine, mode and dose for glutamine administration, as well as improvement of certain disease state after glutamine supplementation. Even though immunonutrition has not been widely assimilated by clinicians other than nutritionists, immunonutrients including glutamine may exert beneficial influence on diverse patient populations.

Glutamine supplementation reduces markers of intestinal permeability during running in the heat in a dose-dependent manner

Purpose: To examine the dose-response effects of acute glutamine supplementation on markers of gastrointestinal (GI) permeability, damage and, secondary, subjective symptoms of GI discomfort in response to running in the heat.

Methods: Ten recreationally active males completed a total of four exercise trials; a placebo trial and three glutamine trials at 0.25, 0.5 and 0.9 g kg-1 of fat-free mass (FFM) consumed 2 h before exercise. Each exercise trial consisted of a 60-min treadmill run at 70% of [Formula: see text] in an environmental chamber set at 30 °C. GI permeability was measured using ratio of lactulose to rhamnose (L:R) in serum. Plasma glutamine and intestinal fatty acid binding protein (I-FABP) concentrations were determined pre and post exercise. Subjective GI symptoms were assessed 45 min and 24 h post-exercise.

Results: Relative to placebo, L:R was likely lower following 0.25 g kg-1 (mean difference: - 0.023; ± 0.021) and 0.5 g kg-1 (- 0.019; ± 0.019) and very likely following 0.9 g kg- 1 (- 0.034; ± 0.024). GI symptoms were typically low and there was no effect of supplementation.

Discussion: Acute oral glutamine consumption attenuates GI permeability relative to placebo even at lower doses of 0.25 g kg-1, although larger doses may be more effective. It remains unclear if this will lead to reductions in GI symptoms. Athletes competing in the heat may, therefore, benefit from acute glutamine supplementation prior to exercise in order to maintain gastrointestinal integrity.
