Take one shot (approx. 1 tbsp / 15ml) daily. While there are some added benefits to taking it in the morning on an empty stomach, you can take it any time of day for the polyphenol benefits. Research suggests consuming olive oil before eating may support satiety and blood sugar regulation. Drink it straight, drizzle over yogurt, bread, or add to a smoothie. Consistency matters more than timing.

Yes. Kosterina EVOO is rich in oleocanthal, a polyphenol with anti-inflammatory effects comparable to a low dose of ibuprofen in peer-reviewed research. The peppery sensation at the back of your throat when you take a shot is oleocanthal in action. With over 1000+ mg/kg polyphenols, Kosterina exceeds the EU authorised health claim threshold by over 4x.

Yes -- and it is among the strongest dietary evidence available. The PREDIMED trial (New England Journal of Medicine) is the largest randomised olive oil intervention study ever conducted. A 2024 JAMA Network Open study found 7g+ of olive oil daily was associated with a 29% lower risk of dementia-related death. A 2025 study confirmed daily high-polyphenol EVOO significantly reduced HbA1c, a key blood sugar marker. The critical detail: these benefits require high-polyphenol oil. Most supermarket EVOOs contain ~150 mg/kg. Kosterina EVOO Shots use 1000+ mg/kg -- the concentration that matches clinical research.

Research increasingly supports olive oil's role as a prebiotic. Olive oil polyphenols pass through the stomach largely intact, arriving in the colon where they feed beneficial bacteria -- including Bifidobacterium and Lactobacillus strains. A 2025 human study confirmed that daily high-polyphenol EVOO shifted gut microbiota toward healthier compositions and reduced the inflammatory marker IL-1 beta. Kosterina EVOO Shots provide a convenient daily dose of 1000+ mg/kg polyphenol oil to support your gut microbiome.

Research, including the PREDIMED trial, shows that consuming at least 1-4 tablespoons (15-60ml) of high-polyphenol EVOO daily is associated with meaningful cardiovascular, cognitive, and anti-inflammatory benefits. The EU authorised health claim for olive oil requires 20ml (approximately 1.5 tablespoons) per day of oil with 250+ mg/kg polyphenols. Kosterina EVOO Shots make hitting this target simple -- one shot per day is all you need to start.
