Kosterina EVOO delivers clinically studied health benefits. Its polyphenols -- particularly oleocanthal, hydroxytyrosol, and oleuropein -- reduce inflammation, lower LDL (bad) cholesterol, raise HDL (good) cholesterol, and protect cells from oxidative damage. The landmark PREDIMED trial (7,447 participants, NEJM) found that a Mediterranean diet supplemented with EVOO reduced cardiovascular events by approximately 30%. Regular consumption is also associated with improved cognitive function and a 29% lower risk of dementia-related death (JAMA Network Open, 2024).
