Overview

NOW Foods L-Glutamine provides 1000mg of free-form L-glutamine per capsule. Glutamine is the most abundant amino acid in the body, comprising 60% of the free amino acid pool in skeletal muscle. It serves as the primary fuel source for enterocytes (intestinal lining cells) and immune cells (lymphocytes). During intense exercise, illness, or stress, glutamine demand can exceed the body's production capacity, making supplementation beneficial. The capsule form provides convenience over powder for those who prefer precise dosing.
