The Science Behind High-Polyphenol Extra Virgin Olive Oil

ATSAS is naturally rich in polyphenols — plant compounds valued for their antioxidant properties. This page brings together the science, the EU-recognised health claim, and the evidence behind our high-polyphenol extra virgin olive oil.

Why ATSAS Is Different

ATSAS extra virgin olive oil is produced from organically grown olives in Cyprus, cold-pressed to preserve the full spectrum of naturally occurring polyphenols. Our focus on careful harvesting, small-batch production and independent laboratory analysis means every bottle delivers consistently high polyphenol levels — not just a premium label.

ATSAS is available as a traditional extra virgin olive oil, as a daily food supplement shot, and in beautifully presented gift sets — making it easy to include in any routine.

The EU Recognised Health Claim

This is one of very few food-specific antioxidant claims recognised under EU nutrition and health regulation — and ATSAS is produced with this standard in mind.

What Are Polyphenols?

Polyphenols are naturally occurring plant compounds found in olives and extra virgin olive oil. They are among the most researched antioxidant compounds in nutrition science, valued for their ability to help protect cells from oxidative stress. High-polyphenol olive oils — like ATSAS — contain significantly higher concentrations of these beneficial compounds compared to standard commercial olive oils.

A simple sign of a high-polyphenol olive oil is its taste: a pleasantly peppery, slightly bitter finish that signals active phenolic content straight from the grove.

What the Research Explores

Scientific interest in olive oil polyphenols has grown significantly over recent decades, particularly in the context of the Mediterranean diet. Research has explored several areas of interest:

• Oxidative stress and blood lipids — polyphenols help protect LDL cholesterol from oxidative damage, which is the basis of the EU health claim. Read article..
• Cardiovascular health — olive oil remains one of the most studied foods in relation to heart health, particularly within long-term dietary research. See the research..
• Inflammation — phenolic compounds including oleocanthal have been studied for their potential anti-inflammatory properties. More to explore..
• Brain health and healthy ageing — a growing area of research exploring the role of polyphenols in neuroprotection and cognitive function over time. Explore the research..
• Bone health — research has explored the role of olive compounds in supporting bone density and mineral metabolism, including synergistic effects with Vitamin D. Find out more..
• Gut health — emerging research into how polyphenols interact with the gut microbiome and digestive health. Read more..
