You’ve heard of ginger-turmeric shots and green juice shots, but this one might just become your healthiest daily ritual yet.
Introducing the Kosterina High-Phenolic Extra Virgin Olive Oil Shot, developed in partnership with physician and scientist Dr. William Li, author of Eat to Beat Disease. With over 1,000 mg/kg of polyphenol content, this small but mighty shot delivers a powerful dose of antioxidants that support your heart, metabolic, gut, skin, and immune health - all in one golden sip.
Pure, Potent, and Straight from Greece
Our Extra Virgin Olive Oil Shots are made from just one ingredient: Ultra High-Phenolic Organic Extra Virgin Olive Oil from Greece.
This super early-harvest, cold-pressed, monovarietal olive oil comes from our family groves in southern Greece, where the olives are hand-picked at peak freshness and pressed within hours to preserve their natural antioxidant content.
Each pre-measured bottle delivers the perfect daily dose so you can enjoy the health benefits of high-phenolic olive oil anytime, anywhere.
Expect a bold, peppery taste - that gentle kick in the back of your throat means the polyphenols are doing their job. Enjoy it straight, mix it with a splash of citrus, or drizzle it over your morning greens.
This is wellness in its purest form - powered by nature, perfected by science.
Developed in Partnership with Dr. William Li
We teamed up with Dr. William Li, world-renowned physician, scientist, and New York Times bestselling author of Eat to Beat Disease, to identify the ideal dosage and concentration for meaningful health impact.
Together, we created an olive oil shot that goes beyond culinary - one that’s designed to nourish the body’s key health systems at a cellular level.
Each 20-gram shot (about one tablespoon) delivers the optimal daily amount shown in human studies to support five key areas of wellness:
- Supports cardiovascular health
- Supports metabolic health
- Supports immune health
- Supports gut health
-
Supports skin health
Why “High-Phenolic” Matters
Polyphenols are the heart of olive oil’s health story — naturally occurring plant compounds with powerful antioxidant and anti-inflammatory effects.
While most supermarket olive oils contain between 100–250 mg/kg of polyphenols, Kosterina’s High-Phenolic EVOO Shot contains over 1,000 mg/kg, making it one of the most potent on the market.
High-phenolic olive oil has been linked in dozens of human studies to stronger cardiovascular health, improved metabolism, and better overall longevity. Here’s what the science says about how it supports your body from the inside out:
- Stronger immune defense and lower inflammatory markers→ A 2025 systematic review and meta-analysis of 15 randomized controlled trials (2,477 participants) found that Mediterranean diets supplemented with olive oil significantly reduced key inflammatory biomarkers, including interleukin-6 (IL-6) and C-reactive protein (CRP), while improving endothelial immune function by lowering adhesion molecules such as sICAM-1 and VCAM-1.Source: Nutrition & Metabolism, 2025
- Improved heart and vascular health, including reduced LDL oxidation and lower cardiovascular risk→ In a meta-analysis of over 800,000 participants, higher olive oil intake was associated with a 16% lower risk of cardiovascular disease and a 22% lower risk of type 2 diabetes. Source: PubMed, 2022
- Better metabolic health, with improved insulin sensitivity and reduced diabetes risk→ A 2024 meta-analysis of 10 studies (over 500,000 participants) found that moderate olive oil intake (10–20 g/day) reduced diabetes risk by up to 22%. Source: PubMed, 2024
- Enhanced gut health and microbial diversity→ A 2019 review published in Nutrients found that olive oil rich in phenolic compounds such as hydroxytyrosol promotes a balanced and diverse gut microbiome, increases populations of beneficial bacteria like Lactobacillus and Bifidobacterium, and reduces inflammatory markers such as IL-6 and TNF-α. These effects help strengthen gut barrier integrity and support digestion and immune balance. Source: PubMed, 2019
- Healthier, more resilient skin thanks to improved cellular repair and reduced oxidative damage→ A cross-sectional study of 2,919 adults found that higher intake of monounsaturated fats from olive oil was associated with a significantly lower risk of severe skin photoaging, whereas MUFAs from animal fats showed no benefit. Researchers concluded that olive oil’s unique blend of MUFA, squalene, and polyphenols may help protect against UV damage and skin aging. Source: PLOS One, 2012
In other words: one tiny bottle, a whole lot of science.
The Science of Small Doses
Dr. Li’s research and meta-analyses show that 10–20 grams per day (roughly one Kosterina EVOO Shot) is the “sweet spot” for the body to reap olive oil’s protective benefits — with no added advantage at higher doses.
That’s exactly what our pre-measured shot delivers — no guesswork required. Just one daily olive oil shot for whole-body wellness and longevity support.
How to Take Your EVOO Shot
You can enjoy your Kosterina shot:
- Straight up — think of it as your daily Mediterranean wellness ritual
- With lemon or orange juice — for a bright, citrusy balance
- Over yogurt, avocado toast, or salads — no heat, all health
There are added benefits to taking the shot first thing in the morning before food but you can take your shot anytime of day - with or without food. Check out a recent weekly wellness article where we dove deep into this topic.
And that natural peppery kick? It’s a sign your oil is alive with polyphenols — the exact compounds that give high-quality extra virgin olive oil its distinctive taste and health benefits.
Why We Chose Opague Glass Packaging
Light, heat, and oxygen are the enemies of fresh olive oil. Studies show that dark glass bottles best preserve the antioxidants and phenolic compounds that make EVOO so special.
That’s why every Kosterina EVOO Shot is packaged in dark glass - protecting its potency and freshness from farm to shot.
