L-Glutamine is the most plentiful amino acid in the body and is viewed as essential for gut lining integrity and muscle preservation. This form is free-form L-glutamine, shown up in a vegetarian capsule for delivery as a single-ingredient supplement.

This product uses a high-strength, single-ingredient amino acid formulation with the capsule shell and tiny stabilisers picked to minimise allergens and maximise purity.

What Does L-Glutamine Do?

L-Glutamine helps support intestinal mucosal integrity and may aid in keeping barrier function up during metabolic stress. It's also tied to muscle recovery contexts in athletic and clinical settings, aligning with evidence on gut and muscle health support.

Scientific discussions recognise its role as a fuel source for cells of the gut lining and immune system, with studies noting improvements in intestinal barrier function and GI comfort under stress. NHS and EFSA guidance emphasise normal physiological roles of amino acids in metabolism.

Dr. Zuhl from the University of Idaho found that glutamine supplementation can improve markers of intestinal barrier function and reduce GI symptoms in stressed or athletic individuals.

This supplement isn't intended to diagnose, treat, cure, or prevent any disease.
