Sensitive liver enzyme and marker of oxidative stress. Predicts cardiovascular and metabolic disease risk.
GGT (gamma-glutamyl transferase) is a liver enzyme that responds sensitively to oxidative stress, alcohol consumption, and certain medications.
Elevated GGT can be an early sign of fatty liver, even before ALT rises. It also indicates disruption of glutathione metabolism.
Research shows that lower GGT levels are associated with longer lifespan and lower chronic disease risk.
Note: GGT is extremely sensitive to alcohol consumption. Even moderate drinking can significantly elevate it. For accurate evaluation, consider retesting after 2-4 weeks of complete abstinence.
