Last updated: June 2026 · Reviewed by the FactoWiki Editorial Team for clarity and source accuracy
Quick summary
Ellagic acid is a polyphenol from berries and pomegranate, marketed for antioxidant and 'anticancer' support. Lab findings are promising; human evidence is limited.
What is Ellagic Acid?
Ellagic acid is a polyphenol antioxidant found in pomegranates, raspberries, strawberries and walnuts, sold as an antioxidant supplement. The body also converts related compounds into urolithins.
What Ellagic Acid is commonly used for
In supplements, Ellagic Acid is most often included for skin & anti-aging, men's vitality support. It is used as nutritional support, not as a treatment for any medical condition — the distinction matters, because the claims on a sales page are often stronger than the evidence allows.
How Ellagic Acid works
Ellagic acid has antioxidant and anti-inflammatory activity in the laboratory and, via gut conversion to urolithins, may influence cell and mitochondrial health, the basis for its marketing.
What the evidence says
Here's an honest snapshot of what published research suggests about Ellagic Acid — including where the evidence is limited.
- Most ellagic-acid evidence is from laboratory and animal studies; human trials are limited, so the antioxidant and 'anticancer' claims are not established. Eating ellagitannin-rich fruits is the proven, healthy route.
- Study quality and doses vary, and a result seen in research doesn't guarantee the same for any individual — use the sources below to check the current evidence on Ellagic Acid rather than relying on marketing claims.
Typical dosage used in studies
Supplement doses vary; absorption of ellagic acid is poor, with much of the benefit depending on gut conversion to urolithins. This is general information from research, not a personal recommendation or a dosing instruction.
Side effects and safety
Ellagic acid from foods is very safe; concentrated supplements have limited long-term data and may interact with medications processed by the liver. As with any supplement, it's sensible to introduce Ellagic Acid on its own, use a trusted brand, and stop if you notice any reaction.
Medication interactions and who should avoid Ellagic Acid
Medication & safety check
Ellagic Acid can interact with certain medications or health conditions in ways that aren't always obvious. If you take any regular medication, are pregnant or breastfeeding, or manage a health condition, confirm Ellagic Acid is appropriate for you before starting.
This is general information, not personal medical advice. If you take any medication, are pregnant or breastfeeding, or have a health condition, confirm it's safe to use Ellagic Acid with your doctor or pharmacist first.
