Daily high-polyphenol EVOO is one of the most studied dietary habits in longevity research. The PREDIMED trial (7,447 participants, NEJM) found a Mediterranean diet with EVOO reduced cardiovascular events by ~30%. A 2024 JAMA Network Open study linked daily olive oil to a 29% lower risk of dementia-related death. Each Kosterina EVOO Shot delivers over 1000+ mg/kg polyphenol oil -- the grade used in clinical research. Research has also proven that a daily EVOO shot supports five key areas of your health: heart health by reducing cardiovascular risk, metabolic health by improving insulin sensitivity, immune health by lowering inflammation, gut health by promoting a balanced microbiome, and skin health by protecting against oxidative damage.
