The Active Ingredient Is: L-Glutamine (L-Glutamine)

L-Glutamine is a conditionally essential amino acid that serves as a key fuel for rapidly dividing cells in the gut and immune system, and acts as a nitrogen shuttle for inter-organ transport.

This product provides pure L-glutamine produced by microbial fermentation, making it suitable for vegan diets and non-GMO. The formulation delivers the amino acid on its own, with inactive ingredients limited to plant-based binders where applicable.

What Does L-Glutamine Do?

L-Glutamine supports intestinal cell function and helps maintain intestinal barrier integrity, while contributing to the synthesis of other amino acids and nucleotides. It also serves as a precursor for the antioxidant glutathione, supporting cellular health in tissues such as the gut and immune system.

Overall, this amino acid participates in normal metabolic processes related to gut and immune system function, aligning with recognised nutrient roles in human physiology.
