Nutricost L-Glutamine Powder 5000mg
by Nutricost
"Pure L-glutamine powder for gut health, immune function, and muscle recovery — 100 servings at bulk value"
Overview
Nutricost L-Glutamine Powder provides 5000mg of pure L-glutamine per scoop — the most abundant amino acid in the body and the primary fuel source for intestinal cells (enterocytes) and immune cells (lymphocytes). Glutamine supplementation is most valuable for gut health (intestinal barrier integrity), immune function during intense training, and muscle recovery. Glutamine levels can become depleted during intense exercise, illness, or stress, making supplementation beneficial during these periods. The unflavored powder mixes easily into any beverage.
