liver values
You have had blood tests done and the results show elevated liver values. What does this mean exactly? Is it serious? And what can you do yourself? In this article, we explain what liver values are, which factors influence them, and how you can actively support the liver.
Liver values are enzymes and proteins in the blood that provide information about the condition of the liver. When liver cells are damaged, these substances leak into the bloodstream — similar to how a damaged cell loses its contents.
| Value | Normal value | Elevated in |
|---|---|---|
| ALAT (ALT) | < 45 U/L | Liver cell damage, hepatitis |
| ASAT (AST) | < 40 U/L | Liver and muscle cell damage |
| GGT (gamma-GT) | < 55 U/L | Alcohol use, bile duct problems |
| ALP (alkaline phosphatase) | 35–105 U/L | Bile ducts, bones |
Even moderate regular alcohol consumption can structurally increase GGT. The liver processes alcohol by converting it into acetaldehyde — a toxic byproduct that damages liver cells.
Overweight, insulin resistance, and a diet rich in processed carbohydrates are the main causes. ALAT and ASAT are often mildly to moderately elevated in fatty liver disease.
Paracetamol, statins, and contraceptive pills can all affect liver values. No reason to stop medication, but do support the liver additionally.
Mild elevations (up to 2–3× the normal value) are often monitored by doctors. For higher elevations, or with jaundice, abdominal pain, or extreme fatigue, further investigation is needed. Always consult a doctor for persistently elevated liver values.
Milk thistle (silymarin) — meta-analyses show significant reduction of ALT and AST in fatty liver and alcoholic liver disease.
NAC (N-acetylcysteine) — increases glutathione production and protects liver cells from oxidative damage. Clinical studies confirm reduction of ALT and AST in elevated liver values.
