Glutamine
TL;DR
L-Glutamine is the most abundant amino acid in the body and conditionally essential during stress, illness, or intense exercise. It is the primary fuel for enterocytes (gut lining cells) and lymphocytes.
Overview
L-Glutamine is the most abundant amino acid in the body and conditionally essential during stress, illness, or intense exercise. It is the primary fuel for enterocytes (gut lining cells) and lymphocytes. Depletion during catabolic states impairs immune function and gut barrier integrity. Critical for recovery.

Interactions
synergistic. L-Glutamine fuels enterocytes and maintains tight junctions in the gut barrier while probiotics optimize the microbial ecosystem inside; complementary gut health support
synergistic. Glutamine provides the glutamate portion of glutathione (gamma-glutamyl-cysteinyl-glycine) while NAC provides the cysteine; together they supply 2 of 3 glutathione precursors
enhances. Glutamine is converted to ammonia in the body; in liver cirrhosis, impaired ammonia clearance can worsen hepatic encephalopathy
synergistic. Both support gut barrier integrity — glutamine fuels enterocyte metabolism while zinc stabilizes cell membranes and supports tight junction protein expression
