Liver supplements: what is actually compared

Last reviewed 21 October 2026 · SupplementScore editors · No sponsorships

Best for liver is a shop label. This page does not crown a winner the trials did not crown. It points at the comparisons already published and at the claims to ignore.

Start with the comparisons we already publish

• Milk thistle vs TUDCA
• TUDCA vs NAC
• Milk thistle, TUDCA, NAC
• TUDCA article

Those pages carry their own citations. This one does not paste new percentages on top of them.

What to skip

• Detox teas and liver flushes. See why detox teas are dangerous. A supplement does not rinse a liver.
• Stacking preformed vitamin A. Cod liver oil is discussed on fish oil vs cod liver oil and on vitamin A toxicity. Do not add a vitamin A pill on top without reading that.
• A GLP-1 nickname for a liver pill. Berberine's glucose data are not a liver-cure claim. See GLP-1 supplements.

Questions people ask

What is the best liver supplement?

There is no new winner on this page. Use the milk thistle, TUDCA, and NAC comparisons, and skip detox teas and flushes.

Can a supplement clean the liver?

Nothing we publish here shows a rinse or a flush. Those words are marketing.
