  • 100% pure, never blended
  • Single-origin sourced from Italy
  • Third-party tested for purity and potency
  • Non-GMO and certified organic

A small-batch, early-harvest, 100% Italian Organic EVOO from 500-year-old olive trees in the Marche region of central Italy — pure, unblended, and cold-pressed within hours of harvest to preserve its naturally high polyphenol content.

Crafted by a multi-generation Italian family using strict organic methods, from ancient native cultivars including Carboncella, Sargano, Ascolana, Piantone, Frantoio, and Moraiolo.

Bold, peppery, and unmistakably fresh — the pepper is from the high concentration of polyphenols. The stronger the bite, the more of them are present!

Current bottles are from the 2025 Fall harvest.

Why Dr. Mayer recommends this

Most olive oils on the shelf are good enough to cook with, but very few are genuinely health-promoting. Ours comes from organically grown trees that have made enough polyphenols to thrive for hundreds of years. I know the owner personally, I have witnessed the harvest and the cold pressing many times, and I have studied polyphenols for decades.

Dr. Emeran Mayer, MD · Gastroenterologist & Cofounder

Crafted the Way It Should Be

This olive oil carries the mark of generations. Grown on a single Italian estate, each tree has been carefully tended over decades, many tracing back hundreds of years. Our olive oil is never blended, preserving the character of their specific grove and the subtle nuances of the region.

Small-batch production and direct-to-consumer availability ensure every bottle delivers a flavor and aroma that could only come from this place and these hands. It’s an oil that reflects history, tradition, and a commitment to craftsmanship.

What's Actually in the Bottle

Most olive oil producers never print polyphenol content on a label. There is no requirement to, and testing costs money. So most people are left guessing, or judging by how dark the bottle is. We test ours and publish the result.

Total polyphenols
773 mg/kg
~11 mg per tablespoon
Free acidity
0.19%
Against a 0.8% legal limit for extra virgin
Peroxide value
6.2 meq O₂/kg
Against a 20 limit for extra virgin
Pesticide screen
150+ residues tested
None detected

Acidity and peroxide value measure how carefully the fruit was handled and how fresh the oil is. Polyphenol content is what the research focuses on. All three come from lab analysis of the current lot.

Everything on the Label, Nothing Hidden

Most olive oil is blended from multiple farms and often multiple countries. Ours comes from a single estate in the Marche region, pressed from six native Italian cultivars: Carboncella, Sargano, Ascolana, Piantone, Frantoio, and Maraiolo.

Several of the trees are centuries old. They were planted by the family that still farms them, and they produce a fraction of what modern high-density groves yield. That is part of why this kind of oil stays small.

The six varieties are harvested and pressed together, which is what gives the oil its particular character. It is not a formula that can be reproduced elsewhere.

Polyphenols

The compounds that give early-harvest oil its bitterness and peppery finish. This bottle tests at 773 mg/kg, roughly 11 mg per tablespoon. Most producers never publish the number, which is part of why it varies so widely between brands.

Oleocanthal

The specific polyphenol behind the catch you feel at the back of your throat. It is present in fresh, early-harvest oil and fades as oil ages, which is why supermarket olive oil rarely has it. It is among the most heavily studied compounds in olive oil research.

Monounsaturated fats

Roughly three quarters of olive oil by weight is oleic acid, a monounsaturated fat. It is the reason olive oil holds up better to heat than most seed oils, and the component most often cited in Mediterranean diet research.

Committed to Science, Not Trends

Wellness has been overtaken by influencers and self-proclaimed gurus, most of them working without a scientific foundation. Meanwhile the real research on the brain-gut connection, polyphenols, and the microbiome sits locked in academic journals where almost no one reads it.

Mayer Nutrition exists to close that gap. Founded by Dr. Emeran Mayer, a gastroenterologist and neuroscientist who has spent his career studying the links between the gut, brain, and microbiome, alongside Dylan Mayer, MS, whose background is in neuroscience, nutrition, and human performance.

Every product is research-driven, built on ingredient integrity, and transparent by design. You should know exactly what you are putting in your body.

    Insane flavor & my new pantry staple!

    This is hands down one of the best EVOOs I’ve ever had! It has such a bold, fresh flavor and a peppery bite, you can literally taste how high quality it is! My favorite way to eat it is drizzled on top of salads or as a dipping sauce for fresh bread. It is so good that I actually prefer to use it by itself so the flavor can really shine. I will 100% be repurchasing & gifting to friends!!

    Better, cleaner taste

    Mayer Nutrition Extra Virgin Olive Oil has leveled up my salad game. I've been using quality organic olive oils on salads for a many years. I love olive oil. The good ones all seem pretty much the same to me, so I had no brand loyalty. Not anymore. Mayer Nutrition's just tastes better. Cleaner. Definitely will be ordering more.
