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

L-Glutamine is an amino acid that acts as a building block for proteins and supports everyday metabolic function.

This formulation uses L-Glutamine produced by microbial fermentation, offering a clean, vegan-friendly source with high bioavailability.

What Does L-Glutamine Do?

Muscle maintenance and recovery are helped as L-Glutamine contributes to tissue repair after exercise. It also supports immune and gut health under physical stress, aligning with EFSA-referenced functions for this amino acid.

Scientific research suggests these roles in response to stress and exercise, emphasising the nutrient's involvement in immune function and gut barrier support as part of ordinary physiology.

Dr. Novak of University of Copenhagen found that glutamine may support immune status and gut barrier function under stress in clinical contexts.
