The Active Ingredient Is: L-Glutamine

L-Glutamine is basically a non-essential amino acid and the most plentiful free amino acid in muscle and plasma, playing a key role in supporting tissue repair and metabolic function.

This formula is derived from vegan fermentation and meets purity standards, delivering a high-quality, plant-based glutamine with strong solubility and assurance of quality.

What Does L-Glutamine Do?

L-Glutamine helps with immune function and gut health, and it acts as fuel for rapidly dividing cells in immune and intestinal tissues, contributing to normal tissue repair and protein synthesis.

Dr. Ziegler from the university notes that L-glutamine helps immune resilience and gut barrier integrity in physically stressed individuals, aligning with EFSA-backed mechanisms of amino acid metabolism.
