GGT is the key detox metric.
While ALT/AST show liver cell death (damage), GGT (Gamma-Glutamyl Transferase) is a functional marker of biliary health. Elevated GGT (>30 U/L) suggests that your glutathione reserves are depleted and your liver is struggling to keep up with the oxidative load.
It is often the first marker to rise in response to environmental toxin exposure or alcohol, long before significant liver damage occurs.
