This amino acid is a primary energy source for your intestinal cells and is widely present in muscle tissue. Supplementation may be beneficial during physiological stress. Supplementing with L-glutamine may also support a healthy intestinal lining and immune function.

Glutamine is the most abundant amino acid in your body and helps form other amino acids, glucose, protein, and glutathione. Stored in your muscles, it is the primary metabolic fuel for cells in your small intestine, fibroblasts that make collagen, and cells in your immune system. Supplementing with glutamine can support cells that make up your gut lining, resulting in less intestinal permeability and better immune function.
