Pure L-Glutamine powder providing 5 grams per serving to support digestive health, gut lining integrity, and immune-cell energy metabolism.^‡

Glutamine is a key fuel source for intestinal cells, helping support the structure and function of the gut lining.^‡ A healthy gut lining supports digestive resilience and balanced immune function. Immune cells also rely on glutamine for energy, especially during periods of increased metabolic demand.^‡

A clean, unflavored powder tested for purity, potency, and contaminants. Built for daily foundational support.
