Claimed mechanism

Supplements burden the liver; raised ALT/AST prove hepatocyte damage.

Claimed health effect

Liver injury.

Scientific assessment

Mostly false – Essential parts of the statement are not supported by the evidence or are strongly exaggerated.

Certainty of evidence: low – Further research is likely to change the assessment considerably.

1. What was claimed?

Every supplement damages the liver.

2. What is demonstrably correct?

Some supplements do cause liver injury; HDS-induced injury is an increasing share of hepatotoxicity cases, and product quality and contamination are real problems.

3. What is wrong or exaggerated?

The risk is concentrated in specific product classes (anabolic steroids, green tea extract, multi-ingredient products). Ordinary vitamins at recommended doses, whey protein and creatine are not established liver toxins; the statement that liver enzymes rise after 'any' supplement is not supported.

4. What remains unclear?

Long-term safety data for many multi-ingredient products are lacking.

5. Which studies support it?

Navarro 2017 (I-SUP-10) supports a rare, product-specific risk: liver injury was concentrated in anabolic steroids, green tea extract, multi-ingredient and adulterated products; simple vitamins/minerals were 6 of 85 non-steroid cases, and the population incidence of supplement-related liver injury was about 3 per 100,000 persons.

6. Which studies contradict it?

Kreider 2017 (I-SUP-11) on creatine safety (industry COI); Navarro 2017 (I-SUP-10) contradicts the universal parts ('all supplements', 'enzymes raised after any supplement').

7. What applies to Germany and Europe?

In the EU, food supplements are regulated as foods; BfR warns about specific high-dose products (not fetched).

8. What is known about Egypt?

Product quality and counterfeit products may differ; no Egypt-specific data reviewed.

9. What practical conclusion is appropriate?

Avoid bodybuilding 'stacks', anabolic products and multi-ingredient weight-loss products; do not assume that all supplements are equally risky.

Assessment details

Rationale for certainty of evidence

Herbal and dietary supplements cause about 20% of drug-induced liver injury cases in a US research network, mainly anabolic steroids marketed as bodybuilding products, green tea extract and multi-ingredient products – not standard vitamins, minerals, whey or creatine. An ISSN position stand (authors with industry ties) reports creatine to be safe in healthy people up to 30 g/day for 5 years. No evidence was found that 'any' supplement raises liver enzymes.

Source quality

Video statement generalising from real but product-specific hepatotoxicity.

Regional transferability

Supplement regulation is stricter for medicines than for supplements in both EU and Egypt; contamination risks vary.

Individual exceptions

People with liver disease, and users of bodybuilding or multi-ingredient weight-loss products, are at higher risk.

Regional scope of the claim

general (biological/medical)

Last reviewed

25 October 2026 provisional

In plain language

Some supplements, especially bodybuilding products that contain steroids, green tea extracts and mixed weight-loss products, can damage the liver. But ordinary vitamins at normal doses, and well-studied products such as creatine, are not known to harm the liver. The claim that every supplement raises liver values is not supported.

Studies on this claim

Regional context

Germany / EU

In the EU, food supplements are regulated as foods; BfR warns about specific high-dose products (not fetched).

Egypt

Product quality and counterfeit products may differ; no Egypt-specific data reviewed.

What applies in my country?

General scientific assessment

Mostly false Mostly false: liver injury is linked to specific products, not to supplements in general.

This statement concerns biological or medical relationships. The scientific assessment above applies regardless of the country; country-specific food data do not change it.
