NOW Foods L-Glutamine 1000mg
by NOW Foods
"The gut and immune amino acid — 1000mg L-glutamine for intestinal barrier integrity and immune cell fuel"
Overview
NOW Foods L-Glutamine provides 1000mg of L-glutamine per capsule — the most abundant amino acid in the body and the primary fuel source for intestinal epithelial cells and immune cells. Glutamine is 'conditionally essential' — during stress, illness, intense exercise, or gut inflammation, the body's demand exceeds its production capacity. Glutamine supplementation supports intestinal barrier integrity (preventing 'leaky gut'), immune function, and muscle recovery. It's one of the most widely used supplements in clinical nutrition for gut health.
