Synergy
What is happening. Glutamine is a substrate for glutathione synthesis (via glutamate). Combined use supports antioxidant capacity in critical illness and gut health.
Mechanism. Glutamine feeds the gamma-glutamyl cycle that produces glutamate, a glutathione building block. Direct glutathione bypasses synthesis.
Recommendation. Combine for gut and oxidative support. Useful in IBD and post-surgical recovery.
