NOW Foods L-Glutamine Powder 1 lb provides pure pharmaceutical-grade L-glutamine in a convenient 1 pound unflavored powder — the most commonly used size for athletes and those supporting gut health with regular daily supplementation. Glutamine is the primary fuel for intestinal cells and immune cells, and is depleted by intense exercise, stress, surgery, and illness — making supplementation important for gut barrier integrity, muscle recovery, and immune defense. The powder format allows easy dosing in water, juice, smoothies, or protein shakes. NOW Foods glutamine is pharmaceutical-grade, free from fillers and artificial additives, and manufactured in their GMP-certified facility with identity and purity testing. An affordable, versatile foundation supplement for anyone prioritizing gut health and recovery.
