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

L-Glutamine is a non-essential amino acid that acts as a key nutrient for different bodily functions and tissue support. This product offers L-glutamine in a free-form form suitable for everyday use as a single-ingredient supplement.

This formulation is vegan and free from major allergens, highlighting a pure, single-ingredient source of L-glutamine with minimal added components to support routine energy and resilience.

What Does L-Glutamine Do?

L-glutamine is involved in providing energy to intestinal cells and supporting immune cell function, contributing to normal gut and immune system activity. It also helps with muscle recovery by supporting protein synthesis and tissue maintenance, as recognised in nutrient function discussions.

Aligned with EFSA and NHS-informed guidelines for nutrient roles, L-glutamine helps maintain mucosal integrity and overall cellular function, helping everyday vitality and resilience.

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