Which supplements turn up most often in liver injury?
The supplements that turn up most often in liver injury are green tea extract, high-dose turmeric, ashwagandha, garcinia cambogia, kava, black cohosh and bodybuilding products containing anabolic steroids. Herbal and dietary supplements now cause a meaningful share of drug-induced liver injury.
Natural does not mean gentle, and unregulated means the label may not match the bottle.
Tell your doctor everything you take, especially with abnormal liver enzymes, and stop supplements before repeat testing. Dark urine, yellowed eyes or deep fatigue while on any supplement means stop and get tested now.

The supplements that turn up in liver injury
| Result | In short | What it means |
|---|---|---|
| Anabolic steroids and muscle builders | The biggest single group | The most common supplement cause of serious liver injury, often sold as testosterone boosters or SARMs. |
| Green tea extract, concentrated | Well documented | Brewed green tea is fine. Concentrated extract in weight loss pills is the form linked to hepatitis, and a genetic subgroup is more vulnerable. |
| Herbal weight loss and detox blends | Frequent | Multi ingredient blends make the culprit hard to name, and some are contaminated with undeclared drugs. |
| Turmeric and curcumin, high dose | Rising | Case reports have climbed since piperine enhanced high dose products became common. |
| Vitamin A and niacin at high doses | Dose dependent | Both are predictable at high intake, unlike the others here, which are unpredictable reactions. |
| What injury looks like | Do not wait it out | Yellow eyes, dark urine, pale stool, itching, deep fatigue or right sided pain. Stop the supplement and get liver bloods. |
Most people take these with no trouble at all. The point is that supplements are not automatically harmless, not that they are dangerous. Check it against the guidelines.
