Dietary supplements, particularly multi-ingredient weight loss products and illicit anabolic steroids, are a significant and increasing cause of drug-induced liver injury (DSILI), often leading to acute liver failure and transplantation.

Do not assume dietary supplements are safe simply because they are marketed as 'natural' or 'for health.' Products like green tea extract, usnic acid (found in fat burners), and anabolic steroids carry a real risk of severe liver injury, including acute liver failure. If you are taking these supplements, be aware of symptoms like jaundice or fatigue, and disclose their use to your healthcare provider, as they are often underreported.

ModerateSupportsMEDIUM confidence
The occurrence of HDS-related liver toxicity ranges from 2% to 16% of all identified cases of hepatotoxicity included in different drug-induced liver injury (DILI) Registries in Western countries with an increasing prevalence over time in the US... DSILI constitutes an important cause of ALF in transplantation centers.

Why this rating

Evidence is based on case reports, case series, and registry data rather than randomized controlled trials, limiting causal certainty for specific ingredients.
