The Numbers
All 7 Lab-Verified High-Phenolic Olive Oils, Compared
Every oil below publishes independent laboratory results — NMR or HPLC — rather than marketing claims. A typical supermarket extra-virgin measures 100–250 mg/kg of polyphenols; the EU health claim (Regulation 432/2012) starts at 250 mg/kg.
| Oil | Polyphenols (mg/kg) | Verified by / method | Standout |
|---|---|---|---|
| kyoord — Extremely High-Phenolic | 2,012 | HPLC, third-party (re-tested after 3 months) | Highest oleocanthal verified here: 1,260 mg/kg |
| HYPERELEON — Ultra-High-Phenolic (Organic) | 2,000+ | HPLC; certified by Univ. of Athens & World Olive Center for Health | One of the highest verified organic counts in the world |
| The Governor (Organic) | 1,174–1,316 | NMR, World Olive Center for Health | Fresh third-party results published every harvest |
| PJ Kabos — Family Reserve Robust (Organic) | ~699 | HPLC and NMR published | Rare dual-method transparency; USDA Organic, Kosher |
| Blueprint — Cold-Pressed High-Polyphenol | 425 | HPLC; full COA every harvest | Only oil tested non-detect for lead, cadmium, mercury, arsenic (Lead Safe Mama, 2025) |
| Sakellaropoulos — Fyllikon First Harvest (Organic) | High-phenolic (NMR) | NMR-verified; carries the EU health claim | Used in a Harvard T.H. Chan Mediterranean-diet trial |
| Bona Furtuna — Early Harvest (Organic) | 250–400 | Lab-tested | Single estate; trees up to 1,000 years old; 0.12–0.16% acidity |
Figures are from each producer's published lab results, linked on the product pages. Bonham Brands reviews published testing — we are not a laboratory and do not conduct our own testing.

Which One Should You Buy?
For maximum potency: kyoord — 2,012 mg/kg total polyphenols and the highest oleocanthal we've verified (1,260 mg/kg), founded by a cancer researcher, with a stability re-test after three months of storage. If you want certified-organic at the same altitude, HYPERELEON measures 2,000+ mg/kg with certifications from the University of Athens and TÜV Hellas.
For verified freshness every season: The Governor — same-day pressed in Corfu and re-verified by NMR at the World Olive Center for Health every single harvest (1,174–1,316 mg/kg, 0.17% acidity).
For heavy-metals purity: Blueprint — the only olive oil Lead Safe Mama tested non-detect for lead, cadmium, mercury, and arsenic (June 2025), with a full certificate of analysis published every harvest. Its 425 mg/kg is the most modest count here, but no other oil matches its contaminant transparency.
The remaining three — PJ Kabos (rare dual HPLC + NMR transparency), Sakellaropoulos (NMR-verified, included in a Harvard T.H. Chan Mediterranean-diet trial), and Bona Furtuna (single Sicilian estate, 1,000-year-old trees) — each earned a Bonham Gold Label on the same standard: published, independent verification.
How Bonham Brands Verifies
Where These Numbers Come From
Bonham Brands investigates and verifies — we do not run a lab. Every figure above traces to a published source: NMR analyses from the World Olive Center for Health (a non-profit founded by University of Athens pharmacognosy professors), HPLC certificates of analysis published by the producers, and independent heavy-metals testing by Lead Safe Mama. Each product page links the primary sources so you can check them yourself.
