Best Olive Oil for Drinking: Lab-Tested Rankings & Daily Protocol
Andrew Huberman drinks it. Peter Attia recommends it. Dan Buettner studied centenarians who've done it their whole lives. But which olive oil should you actually pour into a shot glass every morning? We lab-tested 38 oils for polyphenol content and taste — here are the ones worth drinking straight.
🧪Lab-Tested Results at a Glance
Why Are People Drinking Olive Oil Straight?
It sounds extreme, but drinking olive oil is neither new nor fringe. In Crete, Sardinia, and southern Spain — regions where centenarians are 10× more common than in the U.S. — people have sipped EVOO before breakfast for generations. What's changed is that we now have the science to explain why it works.
The key insight: not all olive oils deliver the same health benefits. The compounds responsible — polyphenols like oleocanthal, oleacein, and hydroxytyrosol — vary by a factor of 50× between brands. A supermarket "extra virgin" oil might contain 80 mg/kg total polyphenols. The oils we recommend for drinking contain 1,000–2,081 mg/kg. That's the difference between a health food and medicine.
The 2013 PREDIMED trial — the largest randomized controlled trial on Mediterranean diet ever conducted — assigned 7,447 high-risk adults to consume at least 4 tablespoons (60 ml) of EVOO daily. After 5 years, the olive oil group showed a 31% reduction in cardiovascular events compared to the low-fat diet control. Follow-up analysis found those consuming the highest-polyphenol oils had the strongest protection.

Drinking vs. Cooking: Does Raw Consumption Matter?
This is the question Healthline and most articles dodge. The answer, based on the chemistry, is yes — but with nuance.
A 2020 study in Food Chemistry measured polyphenol degradation during common cooking methods. Sautéing at 170°C for 15 minutes destroyed 40–50% of hydroxytyrosol and 25–35% of oleocanthal. Deep frying was worse: 60–75% loss. But here's the twist — short-duration, moderate-heat cooking (under 10 minutes at 120°C) preserved most polyphenols. Drizzling EVOO on a finished dish is nearly equivalent to drinking it raw.
Where raw consumption has a clear edge is bioavailability. A 2023 study published in Nutrients compared polyphenol absorption on an empty stomach versus with a mixed meal. Fasting consumption increased plasma hydroxytyrosol by 40% and oleocanthal metabolites by 28%. The likely mechanism: without competing food molecules, polyphenols have faster transit to the small intestine where absorption occurs.
Bottom line: If you're specifically seeking anti-inflammatory, cardiovascular, or neuroprotective benefits from polyphenols, drinking high-phenolic EVOO on an empty stomach is the most efficient delivery method. It's like the difference between taking a vitamin with or without food — both work, but absorption differs.
What Makes an Olive Oil Good for Drinking?
Not every EVOO belongs in a shot glass. Here are the four criteria we used to evaluate 38 oils for drinkability:
1. Polyphenol Content (≥500 mg/kg)
The EU health claim threshold is 250 mg/kg. For drinking — where you're consuming a concentrated dose — you want at least 500 mg/kg to get meaningful oleocanthal and hydroxytyrosol per tablespoon. Our top picks range from 1,007 to 2,081 mg/kg.
2. Freshness (≤12 months from harvest)
Polyphenols degrade over time. A Journal of Agricultural and Food Chemistry study found EVOO loses 40% of total phenolics within 12 months even when stored properly. For drinking, buy current-harvest oils only. Check the harvest date, not the "best by" date.
3. Taste Profile (personal preference)
High-polyphenol oils taste nothing like mass-market EVOO. Expect intense bitterness (oleuropein), pepperiness (oleocanthal), and green fruit notes. If you're new to drinking EVOO, start with a milder cultivar like Arbequina before graduating to a fiery Koroneiki.
4. Lab Verification (non-negotiable)
Any brand can claim "high polyphenol." We only recommend oils with independent lab results — either HPLC (High-Performance Liquid Chromatography) or qNMR (quantitative Nuclear Magnetic Resonance). If a producer can't show you a Certificate of Analysis, walk away.

The Science-Backed Daily Drinking Protocol
Based on the PREDIMED trial, EU health claim research, and bioavailability studies, here's the optimal protocol for drinking olive oil daily:
Morning EVOO Protocol
Wake up → Wait 10 minutes
Let your digestive system activate. Drink a glass of water first to hydrate the gut lining for better absorption.
Pour 1–2 tablespoons (15–30 ml) of high-polyphenol EVOO
Use a shot glass or measuring spoon. Start with 1 tbsp in week 1 and increase to 2 tbsp by week 3. With a 500+ mg/kg oil, 2 tbsp delivers roughly 15–60 mg of hydroxytyrosol equivalents — well above the EU health claim threshold of 5 mg.
Optional: add lemon juice
Squeeze half a lemon into the oil. Vitamin C enhances polyphenol absorption and the citrus cuts the bitterness. Some add a pinch of black pepper (piperine boosts bioavailability of many plant compounds).
Drink it in one go (or slow sip)
Some people shoot it; others sip like an espresso. The cough from oleocanthal (the "throat burn") is normal — it's the same TRPA1 receptor activation as ibuprofen. A quick water chaser helps.
Wait 20–30 minutes before eating
This window allows polyphenols to reach the small intestine without competition from food. After this, eat breakfast as normal.
⚠️ Important Notes
- Calorie awareness: 2 tablespoons = ~240 calories. Replace other fats (butter, seed oils) rather than adding on top.
- Gallbladder issues: Olive oil stimulates bile release. If you have gallstones, consult your doctor before high-dose consumption.
- Start slow: Some people experience mild nausea or loose stools in the first week. This typically resolves as your gut adapts.
- Medication interactions: High-dose EVOO may enhance blood-thinning effects. If you take warfarin or similar, discuss with your physician.
What Happens When You Drink Olive Oil Daily: The Evidence
Let's move beyond vague "it's healthy" claims and look at specific, dose-dependent outcomes from randomized controlled trials:
❤️ Cardiovascular Protection
The PREDIMED trial (NEJM, 2018): 4 tbsp/day EVOO reduced major cardiovascular events by 31%. A sub-analysis found that each 10g increase in daily EVOO intake was associated with a 10% reduction in CVD risk. The mechanism: oleocanthal inhibits platelet aggregation, hydroxytyrosol prevents LDL oxidation, and oleic acid improves endothelial function.
🧠 Brain Health
Harvard's 28-year cohort study (JAMA Network Open, 2024) of 92,383 participants found that consuming >7g/day of olive oil was linked to 29% lower risk of dementia-related death. Oleocanthal has been shown to enhance β-amyloid clearance across the blood-brain barrier in animal models — a key mechanism in Alzheimer's prevention.
🔥 Anti-Inflammatory
Oleocanthal inhibits COX-1 and COX-2 enzymes — the same targets as ibuprofen. A landmark 2005 study in Nature calculated that 50 ml of high-oleocanthal EVOO delivers roughly 10% of the ibuprofen dose used for pain relief. Over time, this chronic low-dose anti-inflammatory effect may explain olive oil's association with reduced cancer, arthritis, and metabolic disease risk. Read our deep dive: Oleocanthal vs. Ibuprofen.
🩸 Blood Sugar Control
A 2023 meta-analysis in Exploration of Foods and Foodomics found that EVOO consumption significantly improved glycaemic control in type 2 diabetes patients. Polyphenols appear to slow glucose absorption in the intestine and enhance insulin sensitivity. The effect is dose-dependent — higher polyphenol oils produce larger reductions in HbA1c.
💪 Gut Health & Digestion
EVOO polyphenols act as prebiotics, selectively feeding beneficial Lactobacillus and Bifidobacterium species. A 2022 RCT in Nutrients found that 25 ml/day of high-phenolic EVOO for 3 weeks significantly increased gut microbial diversity. Separately, olive oil's mild laxative effect (stimulating bile and intestinal motility) explains its traditional use for constipation relief.

5 Mistakes People Make When Drinking Olive Oil
Using supermarket "extra virgin" oil
A UC Davis study found that 69% of imported olive oils labelled "extra virgin" in US supermarkets failed to meet IOC standards. Many had polyphenol levels under 100 mg/kg — you'd need to drink a cup to match what 1 tablespoon of Pamako delivers. Always check for a harvest date and COA. See: How to Spot Fake Olive Oil.
Drinking oil past its prime
Olive oil is a perishable food, not a pantry staple that lasts forever. After 12 months, polyphenol levels drop by 30-50%. After 18 months, many "extra virgin" oils have degraded to refined-grade quality. For drinking, only use oil from the current or most recent harvest. Learn more: Does Olive Oil Go Bad?
Taking it with a large meal
Polyphenol absorption drops significantly when competing with a full stomach's worth of food. Take your EVOO shot 20-30 minutes before eating, or at least 2 hours after your last meal.
Adding oil on top of existing calories
Two tablespoons of olive oil contains ~240 calories. The health benefits come from replacing other fats (butter, canola, soybean oil) — not adding 240 empty calories to an already sufficient diet. Swap, don't stack.
Storing the bottle in sunlight or near the stove
Light and heat are polyphenol killers. A Food Chemistry study showed that 6 hours of direct sunlight destroyed 30% of hydroxytyrosol. Store in a cool, dark cupboard. Transfer to a smaller dark bottle once the original is half-empty. See our guide: How to Store Olive Oil.
Taste Guide: What to Expect When You First Drink EVOO
If your only reference point is supermarket olive oil, drinking a high-polyphenol EVOO will be a shock. Here's a sensory map:
🍏 Fruitiness
Green apple, fresh-cut grass, tomato leaf, artichoke, green banana. This comes from volatile compounds (hexanal, Z-3-hexenal) and indicates fresh, properly milled oil.
😖 Bitterness
Felt on the tongue, especially the back. Caused by oleuropein — a powerful antioxidant. The more bitter, the higher the oleuropein content. It's an acquired taste but a sign of quality.
🌶️ Pungency (Pepper)
The throat catch and cough. This is oleocanthal activating the TRPA1 pain receptor — the exact same mechanism as ibuprofen. Oils that make you cough are often the healthiest. Read more: Oleocanthal Explained.
💡 Pro tip for newcomers
Start with ONSURI Arbequina — it delivers 1,504 mg/kg polyphenols with the gentlest flavour profile in our rankings. After 2-3 weeks, your palate adjusts and you'll actually start craving the bitterness. Then graduate to SP360 or Pamako for maximum potency.

Frequently Asked Questions
What is the best olive oil for drinking daily?
Based on our lab testing of 38 EVOOs, the best olive oils for drinking daily are Pamako Monovarietal (2,081 mg/kg polyphenols), SP360 Organic (1,711 mg/kg), and P.J. KABOS Phenolic Shot (1,473 mg/kg). Choose based on your taste preference: Pamako is intensely peppery, SP360 is balanced fruity-bitter, and KABOS is medium-intensity — all deliver well above the EU health claim threshold of 250 mg/kg.
Is it safe to drink olive oil every day?
Yes. The PREDIMED trial (7,447 participants over 5 years) demonstrated that consuming 4+ tablespoons (60 ml) of EVOO daily significantly reduced cardiovascular events. The FDA recognizes 1.5 tablespoons daily as heart-protective. Side effects are rare but may include mild digestive discomfort initially. Start with 1 tablespoon and increase gradually.
When is the best time to drink olive oil — morning or night?
Research suggests polyphenol absorption is highest on an empty stomach (morning, 20–30 minutes before food). A 2023 bioavailability study in Nutrients found that fasting consumption increased hydroxytyrosol plasma levels by 40% compared to with-food consumption. However, if it causes stomach discomfort, taking it with breakfast is still highly beneficial.
How much olive oil should I drink per day?
The evidence-based range is 1–4 tablespoons (15–60 ml) daily. The EU health claim requires at least 20g (~1.5 tbsp) containing 5 mg hydroxytyrosol derivatives. The PREDIMED trial used 4 tbsp (60 ml). For most people, 2 tablespoons (30 ml) of a high-polyphenol oil (500+ mg/kg) delivers meaningful health benefits at roughly 240 calories.
Does drinking olive oil help with weight loss?
Olive oil alone doesn't cause weight loss, but the oleic acid and polyphenols in high-quality EVOO may help. A 2021 meta-analysis in Clinical Nutrition found that olive oil-rich diets reduced waist circumference more than low-fat diets. Oleic acid activates oleoylethanolamide (OEA), a satiety signal. The key: replace other fats with olive oil rather than adding it on top of your current diet.
What does drinking olive oil taste like?
High-quality EVOO tastes nothing like the bland yellow oil from supermarkets. Fresh high-polyphenol oil has three signature characteristics: fruitiness (green apple, fresh grass, tomato leaf), bitterness on the tongue (from oleuropein), and a peppery throat catch (from oleocanthal). The throat burn is actually a sign of quality — oleocanthal activates the same TRPA1 receptor as ibuprofen. Milder oils like ONSURI Arbequina (1,504 mg/kg) offer high polyphenols with less bite.
Can I mix olive oil with lemon juice for drinking?
Yes, and there's science supporting it. Vitamin C from lemon juice enhances polyphenol absorption and may protect phenolic compounds from oxidative degradation during digestion. A common protocol is 1–2 tablespoons EVOO + juice of half a lemon, taken on an empty stomach. Some add a pinch of black pepper (piperine further enhances absorption). See our detailed guide on olive oil and lemon shots.
