Extra virgin olive oil
Polyphenols are the cardioprotective dose in olive oil. EU health-claim rules permit the blood-lipid oxidative-stress claim when olive oil provides enough hydroxytyrosol and derivatives, so I prioritize current harvest-linked lab values, producer transparency, exact product-page imagery, and current COA / certificate access over vague marketing or stale leaderboard carryover.
kyoord Extremely High-Phenolic, Pamako, and SP360 currently have the strongest live evidence package I could verify: exact product pages, current harvest-linked values, certificate/COA imagery or PDFs, and exact product imagery.
The caution list stays softer than the podium because current product-level proof is weaker than the older UC Davis market context. Low transparency, no harvest date, and smooth/mild supermarket blends remain the biggest red flags.

kyoord Extremely High-Phenolic Olive Oil
A newly verified current-harvest leader: official kyoord page, exact bottle image, in-stock product data, and a World Olive Center certificate image showing 2,012 mg/kg total polyphenols.

Pamako Monovarietal EVOO
The most conservative PDF-backed runner-up: exact product pages, exact bottle image, and linked analysis PDFs showing 2,000 mg/kg total polyphenols; the UK storefront now advertises 2,081 mg/kg for 2025/26, but the linked PDF still displays 2,000.

Bertolli Extra Virgin Olive Oil Rich Taste
Caution pick, not a fresh accusation: historical UC Davis issues plus weak current harvest and phenolic transparency.
Historical UC Davis 2010 caution · weak current phenolic proof
Pompeian Smooth Extra Virgin
“Smooth” remains a real quality red flag for EVOO, but I removed the non-verified image and softened the claim to a caution framing.

Filippo Berio Extra Virgin
Another cautious mass-market reference point, kept mainly for low-traceability blended EVOO concerns rather than fresh product-level proof.
