What is a high polyphenol olive oil?

High polyphenol olive oil is extra virgin olive oil with a total polyphenol content above 250 mg/kg — the level required to carry the EU health claim. Our range includes oils from 320 mg/kg to 736 mg/kg, all verified by independent laboratory analysis with published certificates.

What polyphenol level should I look for in olive oil?

Research typically recommends oils in the 400–800 mg/kg range for maximum benefit. Any oil above 250 mg/kg carries the EU-authorised health claim. The highest polyphenol olive oil stocked by the Artisan Olive Oil Company is the Le Ferre Coratina at 736 mg/kg, harvested November 2025 in Apulia, Italy.

Does high polyphenol olive oil taste different?

Yes. Polyphenols are responsible for the characteristic peppery, pungent finish felt at the back of the throat. Higher polyphenol oils tend to be more intense, grassy, and sometimes bitter. This intensity fades as the oil ages, which is why early harvest oils consumed fresh have the highest polyphenol counts.

How much high polyphenol olive oil should I take daily?

Most research supporting cardiovascular and anti-inflammatory benefits uses a daily intake of around 20 ml — approximately 2 tablespoons. The EU health claim for olive oil polyphenols is based on this same daily amount.

How do I know polyphenol figures are accurate?

Every polyphenol figure at the Artisan Olive Oil Company comes from a certificate of analysis issued by an independent, accredited laboratory. These certificates are published on each product page — unlike most retailers who list polyphenol counts without any supporting documentation.

High polyphenol olive oils

Understanding Polyphenols

Polyphenols are bioactive substances renowned for their antioxidant properties. In high-polyphenol EVOO, these compounds have been linked to supporting heart health, reducing inflammation, and offering neuro-protective effects. Not all EVOOs are created equal; studies suggest that higher polyphenol content may lead to better health outcomes.

Understanding polyphenol levels

High polyphenol extra virgin olive oils are not all equal. At the Artisan Olive Oil Company, every oil in this range has been independently laboratory tested and achieves a polyphenol content of at least 400 mg/kg — well above the EU health claim threshold of 250 mg/kg. Several of our oils exceed 700 mg/kg, placing them among the most antioxidant-rich olive oils available to buy online in the UK. All oils in this range are: cold-extracted, produced from an early harvest in the season to maximise polyphenol content, from award-winning producers with independent quality certification, and available with UK delivery from our warehouse near London.
