The Active Ingredient Is: L-Glutamine

L-Glutamine is the most abundant amino acid in the body and supports essential processes such as protein synthesis and tissue recovery.

This pure form is an amino acid used by the body to support muscle repair, immune function, and gut barrier maintenance.

What Does L-Glutamine Do?

Dr. Castell of the University of Toronto found that L-Glutamine participates in muscle recovery and supports gut barrier integrity, contributing to normal digestive function. It also assists with supporting immune system activity in line with EFSA-inspired understanding.

In everyday physiology, L-Glutamine participates in amino acid balance and glutathione formation, helping to sustain normal metabolism and cellular health.
