What are polyphenols and why do they matter?

Polyphenols are the antioxidant compounds in real olive oil responsible for its bitterness and pepper. They help protect blood lipids from oxidative stress, an effect authorised by the European Food Safety Authority, and are a major reason the Mediterranean diet supports heart and brain health.

How much polyphenol does WOW Longevity olive oil contain?

WOW Longevity delivers 190 mg of polyphenols per 15 ml serving, far above typical supermarket olive oils, which are often largely stripped of them.

How do you take high-polyphenol olive oil?

One 15 ml spoonful a day, taken neat or poured raw over food just before serving. Avoid cooking with it, as heat destroys the polyphenols.

Oleocanthal: the olive compound that works like ibuprofen

The science · 4 min read · 2026-07-06

Oleocanthal is the polyphenol responsible for the peppery sting of fresh olive oil. A 2005 Nature paper found it inhibits the same COX enzymes as ibuprofen, despite having a completely different chemical structure.

Key points

Oleocanthal causes the throat catch you feel with a fresh, high-phenolic oil.
It inhibits COX-1 and COX-2, the same enzymes ibuprofen acts on.
It is highest in early-harvest, unrefined oil and fades with time and processing.
A spoonful is not a painkiller. It is a window into why the diet lowers inflammation.

Pour a genuinely fresh extra virgin olive oil and swallow it, and you will feel a sharp, peppery catch at the back of your throat, sometimes enough to make you cough. That sensation has a name, and a surprising mechanism behind it.

A discovery by accident

In 2005, a team led by Gary Beauchamp published a short paper in Nature. They had noticed that the throat sting of fresh olive oil felt strikingly like the sting of liquid ibuprofen. They investigated, and found a compound they named oleocanthal, from the olive. Structurally it looks nothing like ibuprofen, yet it inhibits the very same COX enzymes in the inflammatory pathway.

Bitterness as a signal

Oleocanthal is one of the polyphenols, and like the others it is highest in early-harvest, unrefined oil and fades with time and processing. The intensity of the throat catch is a rough, real-time signal of how much of it your oil still contains. Smooth and mild usually means very little. The wider family of these compounds is covered in polyphenols: the whole point of olive oil.

What it does and does not mean

This is not a claim that olive oil is a painkiller, and a spoonful is not a dose of medicine. It is a window into why a diet built on real olive oil is linked, again and again, with lower chronic inflammation and better long-term heart and brain health, as the PREDIMED trial showed. The compound is genuinely there, and you can taste it.

Common questions

What is oleocanthal?

A polyphenol found in fresh extra virgin olive oil. It is responsible for the peppery, stinging sensation at the back of the throat.

Does olive oil work like ibuprofen?

Oleocanthal inhibits the same COX enzymes that ibuprofen does, which was reported in Nature in 2005. It is not a painkiller and should never replace medication, but it does act on the same inflammatory pathway.

Why does good olive oil sting my throat?

That sting is oleocanthal. It is a sign the oil is fresh and high in polyphenols. A mild, buttery oil generally contains very little.
