What are olive oil polyphenols?
Short answer: polyphenols (or phenolic compounds) are natural antioxidants present in virgin olive oil. They give the intense and bitter character in the mouth and protect the oil from oxidation. The most studied are hydroxytyrosol and its derivatives (including oleuropein and tyrosol). Their value goes beyond taste: they are at the heart of a health claim recognised at European level.
The polyphenol level depends on the variety (intense oils contain more of them), on the maturity of the olives at harvest and on freshness. In Tunisia, the Chetoui variety (North) often exceeds the regulatory threshold, which makes it a differentiation argument against mild oils. The technical terms are defined in the glossary.
The EFSA health claim: what regulation 432/2012 says
Direct answer: EU regulation 432/2012 authorises, on the basis of an opinion from EFSA (European Food Safety Authority), a health claim for olive oil polyphenols. The validated wording is:
"Olive oil polyphenols contribute to the protection of blood lipids from oxidative stress."
This claim can only be used if two conditions are met:
- The content threshold: the oil must contain at least 5 mg of hydroxytyrosol and its derivatives (for example the oleuropein complex and tyrosol) per 20 g of oil — i.e. ≥ 250 mg/kg.
- The reference portion: the beneficial effect is only obtained with a daily consumption of 20 g of olive oil, which must be indicated to the consumer.
It's the only health claim officially authorised for olive oil in the Union. Any other unregistered health claim is prohibited and exposes you to a withdrawal or a blockage.
Key takeaway: the claim is not an optional decorative label: it's a conditional right, framed by a quantified threshold and an imposed wording.
The 250 mg/kg threshold in practice
| Element | Value / requirement |
|---|---|
| Regulatory threshold | ≥ 250 mg/kg of hydroxytyrosol and derivatives |
| Regulatory equivalence | ≥ 5 mg per 20 g of oil |
| Reference portion | 20 g of olive oil / day |
| Wording | Imposed by regulation 432/2012 (see above) |
| Required category | Virgin or extra virgin olive oil |
| Proof | Laboratory measurement, reported on the lot's COA |
The measurement of polyphenols does not enter into the classification into categories (see the quality & standards guide): an oil can be a perfect extra virgin with a level below 250 mg/kg. The EFSA threshold is an additional requirement, independent of the criteria of acidity, peroxide or UV.
Check your oil's category with the quality classifier, then request the polyphenol measurement on the lot's COA.
Why it's a major B2B selling point
For a buyer (brand, distributor, e-tailer), being able to display an official health claim changes the value proposition:
- Shelf differentiation: very few oils reach and document the threshold; the claim justifies a premium positioning.
- Reassuring compliance: it's the only authorised health claim, therefore legally safe if the conditions are respected — no risk of blockage for an unregistered claim.
- Consistency with the health trend: the market values antioxidants and the Mediterranean diet.
- Tunisia advantage: intense varieties (Chetoui) frequently reach the threshold, offering a differentiation at a competitive price against Italy.
A high polyphenol level often goes hand in hand with better preservation: these antioxidants slow down the oxidation of the oil. See the preservation guide.
Sidebar: buyer side / seller side
The polyphenol claim is worked on from both sides.
| Angle | What the EFSA claim changes for you | Reflex |
|---|---|---|
| Buyer (importer/brand) | An official health argument adds value to your range | Require the measurement on the COA and check the 250 mg/kg threshold |
| Seller (exporter who sells) | A documented level justifies a premium price | Measure intense lots systematically and communicate the figure |
| Exporter (Tunisia operations) | Claim compliance avoids a blockage | Use the exact wording of regulation 432/2012 |
Seller / exporter side
Having the polyphenols measured and documenting it on the COA turns a simple lot into a value-added product. Offer the figure spontaneously for intense varieties — it's a concrete commercial differentiator. See the quality process.
How to claim the health claim step by step
- Have the polyphenols measured by a competent laboratory, on the lot concerned.
- Check the threshold: at least 250 mg/kg of hydroxytyrosol and derivatives (≥ 5 mg / 20 g).
- Confirm the category: the oil must be virgin or extra virgin.
- Use the authorised wording of regulation 432/2012, without modifying it.
- Respect the conditions of use: indicate the reference portion of 20 g/day.
- Document the level on the COA of each lot — the threshold is verified lot by lot.
Mistakes to avoid with the polyphenol claim
- Believing every extra virgin reaches the threshold: the level depends on the variety and freshness; many oils are below 250 mg/kg.
- Modifying the wording: the text of the claim is imposed; paraphrasing it can render it non-compliant.
- Forgetting the 20 g portion: the condition of use must be communicated to the consumer.
- Inventing other health claims: only the one of regulation 432/2012 is authorised; the others are prohibited.
- Not measuring lot by lot: the level varies from one lot to another; a claim must rely on the lot delivered.
- Confusing polyphenols and category: a high level does not replace the criteria of acidity, peroxide and UV.
Golden rules
- EFSA threshold: ≥ 250 mg/kg of hydroxytyrosol and derivatives (≥ 5 mg / 20 g).
- Wording imposed by EU regulation 432/2012, to be reproduced identically.
- Reference portion: 20 g of oil/day, to be indicated.
- Virgin or extra virgin category required.
- Measurement documented on the COA of each lot — the threshold is proven lot by lot.

FAQ — Polyphenols & the EFSA claim
What are olive oil polyphenols?
Natural antioxidants present in virgin oil (including hydroxytyrosol, oleuropein, tyrosol). They give the bitterness and intensity in the mouth, protect the oil from oxidation and are at the heart of the only health claim authorised for olive oil in the European Union.
What is the polyphenol threshold for the EFSA claim?
≥ 250 mg/kg of hydroxytyrosol and its derivatives, i.e. at least 5 mg per 20 g of oil. Below this threshold, the health claim of EU regulation 432/2012 cannot be used.
What is the exact wording of the claim?
"Olive oil polyphenols contribute to the protection of blood lipids from oxidative stress." This wording is imposed by regulation 432/2012: it must be reproduced without modification to remain compliant.
Which regulation governs this claim?
EU regulation 432/2012, which establishes the list of authorised health claims on foods, on the basis of the scientific opinions of EFSA (European Food Safety Authority).
Can all extra virgin oils carry this claim?
No. The polyphenol level depends on the variety, on the maturity of the olives and on freshness. Many extra virgins are below 250 mg/kg. Only oils whose measurement reaches the threshold, and documented on the COA, can carry the claim.
Why are Tunisian oils interesting on this point?
The Chetoui variety (Northern Tunisia) is intense and often rich in polyphenols, frequently exceeding the threshold of 250 mg/kg. This allows a premium health differentiation at a competitive price against more expensive origins.
How do you prove the polyphenol level?
By a laboratory measurement reported on the lot's COA. Since the level varies from one lot to another, the claim must rely on the lot actually delivered, not on a generic value. See the guide to reading a COA.
Does the claim change the oil's category?
No. Polyphenols do not enter into the classification into categories (extra virgin, virgin). An oil can be a perfect extra virgin without reaching 250 mg/kg. The claim is added value independent of the category criteria.
Can you use other health claims on olive oil?
No. In the European Union, only the polyphenol claim of regulation 432/2012 is authorised for olive oil. Any other unregistered health claim is prohibited and exposes you to a blockage or a withdrawal.
Do you need to indicate a quantity to consume?
Yes. Since the beneficial effect is only obtained with 20 g of olive oil per day, this reference portion must be communicated to the consumer for the use of the claim to be compliant.
Does a high polyphenol level improve preservation?
Yes, indirectly. Polyphenols are antioxidants that slow down the oxidation of the oil, which contributes to better stability over time. See the olive oil preservation guide.
Does the polyphenol level drop over time?
Yes. Polyphenols are progressively consumed as they protect the oil from oxidation; their level decreases with age and poor preservation. A measurement therefore relates to the moment of analysis: favour a recent COA.
Add value to your polyphenol-rich oils
You know what polyphenols are, how the EFSA health claim works, what the exact threshold is and how to use it in compliance. The next step: have your lots measured and document the level to make it a selling point.
