    A: Glutamine is the primary fuel source for rapidly dividing immune cells, including lymphocytes and macrophages. During periods of stress, illness, or intense exercise, the body demand for glutamine increases dramatically. Supplementation helps ensure immune cells have adequate fuel to function optimally.

    A: Glutamine is the preferred energy source for intestinal epithelial cells (enterocytes) that form the gut barrier. It helps maintain the integrity of the intestinal lining, supports tight junctions between cells, and promotes healthy gut permeability — often called supporting a healthy gut barrier.
