The olive oil shot is everywhere.

So is the influencer in a lab coat telling you how to take it. The advice is almost always the same: choose an extra virgin olive oil “rich in polyphenols.”

Good advice. But how would you know?

Not a hack. A regimen.

If you’re reading this, you probably already take your health seriously. You read labels. You know your dose and where it comes from. You don’t take things on faith, and you shouldn’t.

High phenolic olive oil belongs in that company. The EU registered a health claim for olive oil in 2012. Its wording speaks of “olive oil polyphenols,” and it rests on EUROLIVE, a randomized trial of 200 healthy people led by Dr. María-Isabel Covas in Barcelona, built on more than a decade of her research.

The claim: at least 5 mg of the derivatives of hydroxytyrosol and tyrosol in 20 grams of olive oil a day (about 250 mg/kg) protects blood lipids from oxidative damage. Specific level, specific dose. That is a regimen, not a trend.

But a regimen is only as good as what goes into it. A dose that exists on the label and not in the bottle is no dose at all.

A spoonful of olive oil is not new. My partner Athan’s grandmother kept hers in the root cellar, cold even in summer, in Chaidefto, an inland village near Kavala with a name that means caress. In the fifties and for centuries before, there were no doctors in the villages. There was the oil, and there was the cellar. His grandfather had a shot with red wine in the morning before a day in the fields. Simple foods, simple expectations. Long and strong life.

In 2012, Athan took a ferry to nearby Thassos to hear Dr. Prokopios Magiatis present the health benefits of extra virgin olive oil. His first interview with Dr. Magiatis is still online: [YouTube]. That’s when we got hooked and moved to Greece.

Lots has happened since then. Hundreds of producers changing methods. Thousands of people searching for real remedies for wellness as well as illness. Along comes the health claim and on the heels of that, along comes the hype.  “Rich in polyphenols” is a phrase anyone can print on a bottle. It is also a catch-all: a whole family of compounds, and each does different duty. It doesn’t tell you who measured, how, or when. It doesn’t tell you what happened to the oil afterward.

What a regimen is for

I imagine most people reading this are thinking about the long game, like Athan and I do.  The mental acuity and physical vitality you’ll have at seventy. How you recover at fifty. Whether the focus you rely on today will still be there.

The research on high phenolic olive oil and cognitive health, performance and recovery is still early, and I’d rather say so than oversell it. These are questions people are studying, not claims we’re  making. What I can say is this: we’ve witnessed much first hand, the science is backing it, but the caveat is whatever you’re hoping it will do for you, it can only do it if what’s in the bottle is what’s on the label.

This is why we created Aristoleo Certification.

Not to tell producers what to make. Not to tell you what to buy. But to ask three questions, and to insist the answers come from a source other than the one selling the oil.

Is the phenolic content verified?

We require qNMR, which measures the individual active biophenols directly. This matters because each compound does different duty. Other methods give you a total, and a total can hide a lot. And each oil is tested again every harvest.

Is the oil free of defects?

Rancidity first. Our check looks for defects only, not a full sensory panel for flavour and balance. That is a different question. That’s for the olive oil in your kitchen. We’re only talking about the functional food type olive oil. The one with the health claim. High phenolic content doesn’t protect you from rancidity.

Athan once had an oil that tasted off. We have a direct line to a lab, so we tested it. The number was extraordinary [many times the EU threshold]. The oil was rancid, “unfit for human consumption”. On paper, the numbers told one story. In the spoon, another.

Here’s why a number can mislead. The EU claim is written in terms of hydroxytyrosol and its derivatives, and the wording confuses a lot of people. Even the word polyphenols is not exact. In a fresh oil, what you find are the derivatives of hydroxytyrosol, tyrosol, and oleuropein complex: active biophenols, which are the powerhouse within certain oils, based on cultivar, cultivation, harvest time, production, and ultimately maintenance.

When this olive oil is not properly kept, these phenolic compounds revert to the original elements which indicate degradation is in process.

Was it protected after it was made?

Athan’s grandmother didn’t need a standard for maintaining the fresh early harvest olive oil, with its bitterness and pungency. She had a cellar. It was traditional folk medicine dispensed by the thimbleful. Precious. Her grandmother told her.

Active biophenols can degrade by as much as 50% within 12 months when heat, light, air and time are allowed to work on them. Many producers store their oil at 18°C. Our CoolChain™ standard for certification is 12.5 to 15°C, through production, shipping and storage.

What to ask for.

You don’t have to take our word for any of this, or anyone’s. Ask the producer for the phenolic analysis for the current harvest, not a number from some earlier year. Ask which method measured it. Ask whether anyone checked for defects, and ask how the oil was stored and shipped on its way to you. A producer who has the answers will give them readily. One who doesn’t has told you something too.

The phenolic content on the day an oil was bottled is a fact about the past. What you take as a dietary supplement is the oil in your hands today. We recommend buying directly from the producer who has answered these questions, or from a Aristoleo Certified facility that maintains the CoolChain™ standard.

So the next time you’re told to choose an oil “rich in polyphenols,” ask 3 simple questions:

What’s in it, actually?

Is it lab verified fresh?

Protected how?
