Thorne L-Glutamine Thorne L-Glutamine is a pure amino acid supplement designed to support gastrointestinal health, immune function, and recovery from physical stress.* L-glutamine is the most abundant amino acid in the bloodstream and is found in especially high concentrations in the gastrointestinal tract, where it plays a critical role in maintaining intestinal integrity.* Formulated by Thorne, L-glutamine helps support the cells lining the small intestine, making it particularly beneficial during periods of increased physiological demand.* Factors such as intense athletic training, malnutrition, illness, or injury can reduce glutamine availability and impair absorption in the GI tract.* Research suggests that supplemental L-glutamine supports gastrointestinal and immune health and helps restore plasma glutamine levels depleted after prolonged or exhaustive exercise.* It also plays an important role in tissue repair, making it valuable for recovery following physical stress or injury.* Thorne L-Glutamine is ideal for athletes, active individuals, and anyone seeking foundational GI and recovery support.
