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

L-Glutamine is an amino acid that fuels cellular energy for muscle tissue and backs immune function. This product uses pharmaceutical-grade L-glutamine with no fillers or flavours, delivering a pure, single‑ingredient supplement formulation.

This form is pharmaceutical-grade L-glutamine supplied as a free‑form amino acid, created for easy mixing and broad compatibility with other products.

What L-Glutamine Do?

L-Glutamine helps keep muscle repair on track and backs immune health by fueling lymphocytes and supporting gut integrity. It participates in protein synthesis to help support recovery after tough workouts and keep muscle mass when training's intense.

Studies show that glutamine supplementation can support recovery and may help reduce exercise-related muscle damage, contributing to normal bodily functions linked to training adaptations.
