Phenolia is the only supplement combining three complementary polyphenol sources — powdered high-polyphenol olive oil extract, olive leaf extract, and Greek Mountain Tea — for the broadest olive polyphenol panel available. Every batch is verified by HPLC, the gold-standard test, with certificates you can read yourself.

Polyphenols are protective plant compounds — in olives, the best-studied are hydroxytyrosol and oleocanthal. They're what give a truly fresh, early-harvest olive oil its peppery bite, and they're the reason the Mediterranean diet is researched for heart health and healthy aging.

We test every batch with both HPLC and NMR through independent laboratories. HPLC is the gold standard — it measures each polyphenol precisely. Some brands advertise only NMR numbers because they read higher. We publish both and lead with HPLC, because transparency is the whole point. Read: HPLC vs. NMR →

O-Liv is our verified high-phenolic extra virgin olive oil — a food you enjoy daily. Phenolia delivers the same concentrated polyphenol power as 1.5 tablespoons of high-phenolic oil in one capsule, without the oil or calories, plus polyphenols from olive leaf and Greek Mountain Tea that oil alone can't provide.

Early-harvest Koroneiki olives from Greece — the variety and timing that produce naturally high polyphenol levels. We test at the grove, at production, and per batch.

Polyphenol benefits build with consistent daily use. Many customers report changes in recovery and daily energy within weeks, and cholesterol improvements at their next bloodwork. Consistency beats timing — one to two capsules daily, with a meal.
