Glutamine
Ingredient research · L-Glutamine
L-Glutamine is a conditionally essential amino acid that transports nitrogen and fuels cells in the intestine and immune system. The body usually makes enough, but demand can rise during major illness or injury; a prescription oral formulation can reduce sickle cell disease complications, while routine benefits for exercise recovery or gut health are less certain.
- Supports selected intestinal-barrier, absorption, and bowel-function measures in postinfectious IBS-D and during fluorouracil chemotherapy.
- Supports selected glycemic and incretin markers, including glucose-related measures and GLP-1, in diabetes or older-adult metabolic contexts.
