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

L-Glutamine is an amino acid available in a free-form supplement, recognised for its role in normal bodily functions and tissue support.

This formula uses L-Glutamine in its free-form form as the sole active ingredient, delivered in a vegetarian capsule. It is considered a conditionally essential amino acid that supports immune function and acts as a major nitrogen transporter, providing a primary fuel source for rapidly dividing cells.

What Does L-Glutamine Do?

L-Glutamine participates in supporting intestinal barrier function and maintains nitrogen balance, while serving as energy for enterocytes and immune cells, as described in EFSA-aligned evidence and related literature.

Research suggests that supplementation can contribute to brain health through its role in the glutamate transmitter system, with findings from Dr. Thompson of New York University School of Medicine indicating a neurotransmitter precursor function linked to neuronal health.

This product is not intended to diagnose, treat, cure, or prevent any disease.
