The science behind every capsule.
Three Greek polyphenol sources, tested and documented — the honest guide to what makes Phenolia work.
The Science of
Olive Polyphenols
One of the most researched families of compounds in nutrition — and the most misunderstood number on a supplement label. Here is the honest guide.
What are polyphenols?
Protective plant compounds — in olives, a handful do the heavy lifting the research keeps returning to.
Hydroxytyrosol →
Among the most studied dietary antioxidants — researched for protecting LDL cholesterol from oxidation.
Oleocanthal →
The peppery catch at the back of a fresh oil — studied for its natural anti-inflammatory activity.
The broadest olive polyphenol panel — in one capsule
Different plant parts carry different polyphenols. Relying on one source leaves gaps. Phenolia combines three.
Olive Oil Extract
The hydroxytyrosol- and oleocanthal-rich fraction of premium oil — as a powder, without the oil or calories.
Olive Leaf Extract
Rich in oleuropein, a polyphenol the fruit alone doesn't provide in the same way.
Greek Mountain Tea
Sideritis — a traditional Greek botanical with its own distinct polyphenols.

The same oil. Two very different numbers.
A polyphenol figure is only as good as the test behind it. HPLC measures compounds directly and is the IOC-recognized gold standard. NMR can read 2–3× higher for the identical oil.

How many polyphenols do I actually need?
There's no single official target, but the EU recognizes a health claim for olive polyphenols at 5 mg of hydroxytyrosol per day. Consistency matters more than one big dose.
Do polyphenols survive being made into a capsule?
Yes — a powdered extract is more stable than liquid oil, which can lose roughly 40% of its polyphenols within a year. See our testing & certifications.
Are olive polyphenols safe to take daily?
They're a normal part of the Mediterranean diet. As with any supplement, talk to your physician if you're pregnant, nursing, or on medication.
