Polyphenols: A Key Compound In Olive Oil

The phenolic compounds unique to extra virgin olive oil and in particular hydroxytyrosol, lead to powerful health benefits through the following mechanisms...

Healthy Cholesterol

Phenolic compounds, such as hydroxytyrosol, protect cholesterol from oxidative damage in turn protecting the heart from harmful plaque buildup (atherosclerosis).

The evidence for this has been so strong that the European Food Safety Authority (EFSA) reports: “phenolic compounds from extra virgin olive oil are powerful antioxidants and protect LDL cholesterol from oxidative damage”.¹


Hydroxytyrosol neutralizes free radicals and reactive oxygen species protecting cellular molecules as lipids, proteins or DNA and affecting the development of aging, cardiovascular and neurodegenerative diseases.

Studies have shown that extracts of hydroxytyrosol and olive oil prevented oxidative DNA damage in human immune cells.² 


EVOO-derived phenolic compounds have been shown to reduce inflammation, a key mechanism of aging and cardiovascular disease.

In one prospective cohort study of 315 participants in the European Prospective Investigation into Cancer and Nutrition, hydroxytyrosol was significantly associated with lower levels of high-sensitivity C-reactive protein (hsCRP), a widely used marker of inflammation.³

"Those in the highest [olive oil] consumption category had 19% lower risk of cardiovascular mortality, 17% lower risk of cancer mortality, 29% lower risk of neurodegenerative mortality."

Heart Health

Fewer heart attacks.

Studies have associated high olive oil consumption with an 18% reduction in heart attacks.⁴

These results are derived from a prospective cohort study that included 61,181 women from the Nurses’ Health Study (1990-2014) and 31,797 men from the Health Professionals Follow-up Study (1990-2014) who were free of cancer, heart disease, and stroke at baseline and followed for a total of 24 years. 

Vascular Health

Improved Vascular health

Studies have associated high olive oil consumption with improved elasticity and flow through blood vessels.

These results are derived from a randomized controlled trial of patients with coronary artery disease treated with hydroxytyrosol-enriched olive oil and evaluated by Doppler echocardiography.⁵

Brain Health

Fewer Strokes

Studies have associated high olive oil consumption with a 26% reduction in strokes.⁶

These results are derived from a metanalysis including 38,673 participants from the PREvención con DIeta MEDiterránea (PREDIMED), the European Prospective Investigation into Cancer and Nutrition (EPIC), and the Three-City (3C) prospective cohort studies.

Medical Grade EVOO
  • Outer Capsule: Olivea ensures your daily dose of medical grade extra virgin olive oil sourced directly from Messinia, Greece - the home of the famed Kalamata olive.
20mg Hydroxytyrosol
  • Inner Capsule: We provide 20 mg of hydroxytyrosol in the inner capsule among other phenolic compounds surpassing the EFSA minimum requirements for promoting healthy cholesterol levels.
Capsule in Capsule
  • Olivea's Cap-in-cap technology ensures proper absorption of high amounts of hydroxytyrosol in their natural bioavailable environment.

A single olivea capsule
contains the same amount of hydroxytyrosol
