The Active Ingredient Is: L-Glutamine

L-Glutamine is a conditionally essential amino acid that acts as a primary nutrient for numerous body systems. This product carries pure L-Glutamine in powder form, supplied as a single-ingredient supplement.

It is characterised by its role as an amino acid found in this simple, single-ingredient powder mix.

What Does L-Glutamine Do?

L-Glutamine helps to support immune cell function and enterocyte (gut lining) activity, and it is taken up by muscle cells where it could help support muscle protein synthesis during stressful periods.

Dr. Gleeson from a university found that L-Glutamine is a main fuel for intestinal cells and can take part in muscle recovery processes, reinforcing its role in gut health and post-workout recovery.
