The EU olive oil health claim is the only health claim Europe allows for olive oil polyphenols: "Olive oil polyphenols contribute to the protection of blood lipids from oxidative stress." An oil may carry it only if 20 g (about 1½ tablespoons) contains at least 5 mg of hydroxytyrosol and its derivatives, which works out to about 250 mg/kg. The label must also say the effect comes from 20 g a day. It is an EU rule; it does not apply in the US.
What does the EU olive oil health claim say?
The wording is fixed in law. Commission Regulation (EU) No 432/2012 lists it as:
"Olive oil polyphenols contribute to the protection of blood lipids from oxidative stress."
"Blood lipids" here means fats carried in the blood, mainly LDL particles. "Oxidative stress" means damage from oxidation. The claim says the polyphenols help protect those particles from being oxidised. It does not say olive oil lowers cholesterol, prevents heart disease or treats any condition, and a product carrying it may not say so either.
What are the conditions of use?
The regulation attaches two conditions to the claim:
- A minimum content. The claim may be used only for olive oil that contains at least 5 mg of hydroxytyrosol and its derivatives (for example the oleuropein complex and tyrosol) per 20 g of olive oil.
- A daily amount on the label. The consumer must be told that the beneficial effect is obtained with a daily intake of 20 g of olive oil.
Where does the 250 mg/kg figure come from?
It is the same threshold written per kilogram. 5 mg in 20 g is 0.25 mg per gram. Multiply by 1,000 g and you get 250 mg/kg. When you see "above the EU threshold" or "250+" on an olive oil, this is the line it refers to.
| Per serving | Per kilogram | In kitchen terms |
|---|---|---|
| 5 mg per 20 g of oil | 250 mg/kg | About 1½ tablespoons a day of an oil at that level |
Two cautions. First, the threshold counts hydroxytyrosol and its derivatives, not every phenolic compound in the oil, so a "total polyphenols" figure is not automatically the same number. Second, the regulation does not name a test method. Laboratories use different HPLC approaches, and an NMR figure measures a different set of compounds in a different way. Our guide to HPLC vs NMR testing explains why the method matters.
Who decided this, and on what evidence?
The European Food Safety Authority (EFSA) reviewed the science in 2011. Its panel concluded that a cause-and-effect relationship had been established between eating olive oil polyphenols and protecting LDL particles from oxidative damage (EFSA, 2011). The key human evidence included the EUROLIVE trial, in which 200 healthy men took three olive oils that differed only in phenolic content (Covas et al., 2006). The European Commission then authorised the claim in law in 2012.
The same EFSA opinion looked at other proposed claims for olive polyphenols and did not accept them. EFSA authorised one effect, and that is the only one the law allows.
Does the claim apply in the United States?
No. The EU claim is European law. The US Food and Drug Administration has not authorised it. The FDA has a separate qualified health claim for oils high in oleic acid, including olive oil, which is about replacing saturated fat, not about polyphenols. A US brand quoting the EU threshold is using it as a benchmark, not making an FDA-approved claim.
How do you know if an oil meets the threshold?
Only a lab test can tell you. Look for:
- A certificate of analysis that names the laboratory, the method and the test date.
- A batch or harvest that matches the bottle you are buying.
- A recent date. Polyphenols fall as oil ages, so a result from a year ago may overstate what is in the bottle now.
Pomoni's 2025-harvest oil measured 635 mg/kg total polyphenols by HPLC at Modern Olives in July 2026, and 612 mg/kg at PharmaGnose in February 2026. Both labs also reported the individual compounds that make up hydroxytyrosol and its derivatives. The certificates are on our testing page, and our hydroxytyrosol guide explains the compound behind the claim.

Frequently asked questions
What is the EU olive oil health claim?
"Olive oil polyphenols contribute to the protection of blood lipids from oxidative stress." It is authorised by Regulation (EU) No 432/2012 for olive oil with at least 5 mg of hydroxytyrosol and its derivatives per 20 g.
Why is the threshold 250 mg/kg?
Because 5 mg per 20 g is the same concentration as 250 mg per kilogram of oil.
How much olive oil do you need for the claimed effect?
The regulation ties the claim to a daily intake of 20 g, about 1½ tablespoons, of an oil that meets the threshold.
Does a high-phenolic label mean the oil qualifies?
No. "High phenolic" has no legal definition. Only a dated lab result for that batch shows whether the oil reaches 5 mg per 20 g.
