The Active Ingredient Is: L-Glutamine

L-Glutamine is a non-essential amino acid that is the most abundant free amino acid in the body and serves as a building block for proteins. It supports normal energy needs in cells and helps maintain functioning of tissues such as muscle, immune cells, and the gut lining.

This form is an amino acid supplement intended to support tissue health and metabolic resilience. The primary role of L-Glutamine is to provide a source for muscle and immune cell metabolism and to support gut integrity. This formula also has included other ingredients, which help to support the primary role of L-Glutamine.

What Does L-Glutamine Do?

L-Glutamine is involved in energy supply for immune and gut lining cells and participates in protein synthesis, contributing to normal muscle maintenance. It also acts as a precursor to glutathione, an antioxidant that helps protect cells from oxidative stress.

In health, these functions support everyday tissue health and immune function through normal physiological processes, as recognised by EFSA and NHS guidance where applicable.
