Nutricost L-Glutamine Powder
by Nutricost
"200 servings of pure L-glutamine — 5g per serving for gut health, immune support, and muscle recovery"
Overview
Nutricost L-Glutamine Powder provides 5g of pure L-glutamine per serving with 200 servings per container — making it one of the best value glutamine supplements available. L-glutamine is the most abundant amino acid in the body and is the primary fuel source for intestinal epithelial cells (enterocytes) and immune cells (lymphocytes). During intense exercise, illness, or stress, glutamine demand can exceed supply, leading to gut permeability ('leaky gut') and immune suppression. Supplementation at 5-10g daily supports gut barrier integrity, immune function, and muscle recovery.
