How Much Olive Oil Should You Take Per Day?

The Short Answer

Most research converges on one to two tablespoons (15 to 30 ml) of extra virgin olive oil per day as the amount associated with meaningful health benefits. The FDA has authorized a qualified health claim at 1.5 tablespoons (20g) per day. The landmark PREDIMED trial used closer to 4 tablespoons. The Harvard-led JACC study found lower mortality risk with just over half a tablespoon daily.

What the Research Actually Shows

Multiple large-scale studies have examined olive oil intake and health outcomes. Here is what each found:

Study	Daily Amount Used	Key Finding
FDA Qualified Health Claim (2004)	1.5–2 tbsp (20–23g)	Authorized claim: may reduce coronary heart disease risk when replacing saturated fat
PREDIMED Trial — Spain (7,447 adults)	~4 tbsp (50ml) EVOO	31% reduction in cardiovascular events vs. control diet
Harvard / JACC Study (28 years, 92,000 adults)	More than 0.5 tbsp/day (>7g)	19% lower all-cause mortality; 29% lower neurodegenerative mortality
EFSA Health Claim Standard	1.5 tbsp (20g)	Beneficial effects confirmed when oil contains min. 5mg hydroxytyrosol per 20g
U.S. Dietary Guidelines 2020-2025	~2 tbsp (27g)	Recommended daily oil allowance for a 2,000-calorie diet

 

The PREDIMED trial, published in The New England Journal of Medicine, is among the most rigorous diet trials ever conducted. Participants who supplemented a Mediterranean diet with extra virgin olive oil had a 31% lower risk of major cardiovascular events compared to a low-fat control group. ^[1]

The Harvard-led JACC study — tracking over 92,000 Americans across 28 years — found that people consuming more than 7 grams of olive oil per day had 19% lower all-cause mortality compared to those who rarely consumed it. The benefit extended to cardiovascular, cancer, neurodegenerative, and respiratory mortality. ^[2]

Does the Amount Matter More Than the Quality?

Both matter — but quality may matter more than most people realize.

The European Food Safety Authority (EFSA) has approved a health claim specifically tied to polyphenol content: the claim is only valid when the olive oil contains a minimum of 5mg of hydroxytyrosol and its derivatives per 20g serving. That translates to roughly 250mg of polyphenols per kilogram of oil.

A 2025 study published in NutraIngredients found that even a low dose of high-phenolic EVOO significantly improved cholesterol profiles — suggesting that polyphenol concentration can compensate for a smaller serving size. ^[3]

This is why the type of olive oil you choose — its harvest timing, pressing speed, extraction method, and acidity — directly affects how much benefit you get from your daily intake.

A Practical Daily Intake Guide

Based on the research, here is how to think about your daily olive oil intake by goal:

Goal	Recommended Daily Amount	Notes
General wellness baseline	1–1.5 tbsp (15–20ml)	Meets FDA and EFSA minimum thresholds
Cardiovascular protection	1.5–2 tbsp (20–30ml)	Aligns with PREDIMED supplementation levels
Maximum longevity benefit	2–4 tbsp (30–60ml)	Based on the highest-intake group in the Harvard JACC study
Replace butter/margarine	1:1 substitution	Harvard: up to 34% lower mortality vs. butter users
Polyphenol-targeted dose	1.5 tbsp high-phenolic EVOO	Meets EFSA minimum of 5mg hydroxytyrosol per 20g

Important: these ranges assume the olive oil is replacing saturated fat in your diet, not being added on top of existing fat intake. The FDA health claim specifically states that the benefit comes when olive oil substitutes for saturated fat within the same calorie intake.

How to Hit Your Daily Amount Without Thinking About It

The Mediterranean populations that show the strongest health outcomes from olive oil are not measuring tablespoons. They are using olive oil as their primary cooking fat across every meal. Here is how to build that habit practically:

Morning

•      1 tbsp drizzled on toast, eggs, or avocado — this alone hits the minimum threshold

•      Take it straight — 1 tbsp of high-quality EVOO on an empty stomach is a common practice in olive-growing regions of Greece and Italy

•      Mix with lemon juice as a morning tonic

At meals

•      Use as the base for sautéing vegetables, eggs, and proteins (replaces butter entirely)

•      Dress salads with 1–2 tbsp EVOO instead of store-bought dressings

•      Finish soups, pasta, and roasted dishes with a drizzle before serving — this is both a flavor and nutrition move

•      Dip bread instead of using butter

Evening

•      1 tbsp on steamed or roasted vegetables

•      Use as a finishing oil on grilled fish or chicken

What About the Calories?

A common concern: olive oil is calorie-dense at roughly 120 calories per tablespoon. Two tablespoons add approximately 240 calories to your day.

The research addresses this directly. The PREDIMED study supplemented participants with extra EVOO beyond their normal diet — and still showed significant cardiovascular benefit without adverse weight outcomes. The Harvard study found lower mortality even without controlling for substitution.

That said, the FDA health claim is structured as a substitution: olive oil replacing saturated fat, not added on top. If you are watching total caloric intake, replacing butter, margarine, and refined seed oils with EVOO is the most effective approach — you get the benefit without increasing total calories.

Fat Source Replaced	Mortality Reduction (Harvard JACC)
Butter	Replace with olive oil: 34% lower mortality
Margarine	Replace with olive oil: 34% lower mortality
Mayonnaise	Replace with olive oil: 34% lower mortality
Dairy fat	Replace with olive oil: 18% lower mortality

 

Getting the Most From Your Daily Intake: Why Oil Quality Changes Everything

The research shows that polyphenol content determines a significant portion of the benefit you get from olive oil. An EVOO that was harvested late, pressed days after picking, or stored in clear plastic for 18 months has already lost most of its polyphenols before it reaches your kitchen.

If you are committing to daily olive oil as a health practice, the oil you choose matters as much as the habit itself. 

Four Hour Olive Oil — Built for Daily Use Most olive oils on supermarket shelves are months — sometimes over a year — past their harvest date by the time you buy them. Polyphenols have already degraded significantly. Four Hour Olive Oil is cold-pressed from hand-harvested Ayvalik olives within 4 hours of picking, in an oxygen-free environment with no heat and no added water. The result is a high-polyphenol EVOO with max 0.3% acidity — the kind of oil the EFSA polyphenol health claim was designed for. If you are taking 1.5 tablespoons per day as a health practice, this is the oil that delivers what the research describes. USDA Certified Organic, single-origin, sealed in Italian dark glass.

Frequently Asked Questions

How much olive oil should I take per day?

Most research points to 1 to 2 tablespoons (15 to 30ml) of extra virgin olive oil daily as the amount associated with meaningful health benefits. The FDA qualified health claim is based on 1.5 tablespoons (20g). The PREDIMED trial used approximately 4 tablespoons in a Mediterranean diet context. Start with 1 tablespoon daily and build from there.

Is it better to drink olive oil straight or cook with it?

Both deliver benefits. Drinking it straight — especially on an empty stomach — is a traditional Mediterranean practice and ensures maximum polyphenol absorption. Cooking with it is equally valid; research shows EVOO retains over 70% of its polyphenols after 30 minutes at typical cooking temperatures. The best method is whichever one you will do consistently every day.

Can I take too much olive oil?

Olive oil is calorie-dense at about 120 calories per tablespoon, so very large amounts could contribute to excess calorie intake. The research-backed range is 1 to 4 tablespoons per day. Beyond that, there is no evidence of additional health benefit, and the caloric load increases meaningfully. The FDA specifically frames the benefit as replacing saturated fat, not adding to existing intake.

Does the type of olive oil matter for daily health use?

Yes — significantly. The EFSA health claim for polyphenols is only valid for oils meeting a minimum threshold (5mg hydroxytyrosol per 20g serving). Standard supermarket olive oil often does not meet this threshold. A high-polyphenol extra virgin olive oil from an early harvest, pressed quickly and stored in dark glass, delivers substantially more benefit per tablespoon.

What did the PREDIMED study find about olive oil intake?

The PREDIMED trial — one of the largest dietary intervention studies ever conducted — found that participants who supplemented a Mediterranean diet with extra virgin olive oil at approximately 4 tablespoons per day had a 31% lower risk of major cardiovascular events compared to a low-fat control diet. The study tracked 7,447 adults at high cardiovascular risk over a median of 4.8 years.

What did the Harvard JACC study find?

The Harvard study, published in the Journal of the American College of Cardiology in 2022, followed over 92,000 adults for 28 years. People consuming more than 7 grams of olive oil per day (just over half a tablespoon) had 19% lower all-cause mortality, 19% lower cardiovascular mortality, 17% lower cancer mortality, and 29% lower neurodegenerative mortality compared to those who rarely consumed olive oil.

Should I take olive oil on an empty stomach?

This is a traditional practice in Mediterranean cultures, and there is anecdotal and some clinical support for it — particularly for digestive benefits and maximizing polyphenol absorption before food interferes. Start with 1 teaspoon and increase gradually if your digestive system tolerates it. There is no peer-reviewed evidence that empty-stomach timing outperforms taking it with meals, so consistency matters more than exact timing.

Is 4 tablespoons of olive oil per day too much?

Four tablespoons per day was the supplementation level in the PREDIMED trial and is associated with significant cardiovascular benefit. At 480 calories, it represents a substantial caloric contribution, so it works best in the context of a Mediterranean-style diet where it is replacing other fats rather than adding to them. For most people, 1 to 2 tablespoons is a more practical, sustainable daily target.

Can I get the same benefits from cooking with olive oil as from taking it raw?

Yes. While some polyphenols degrade with heat, high-polyphenol EVOO retains significant antioxidant activity after cooking at normal temperatures. The cardiovascular and longevity benefits observed in Mediterranean populations come from olive oil used across cooking, not just consumed raw. The key is daily, consistent use regardless of method.

What is the EFSA olive oil health claim?

The European Food Safety Authority has approved a health claim for olive oil polyphenols: that they contribute to the protection of blood lipids from oxidative stress. The claim is valid only when the oil contains at least 5mg of hydroxytyrosol and its derivatives per 20g serving, achieved with a daily intake of 20g of olive oil. This is the only EU-approved health claim specifically tied to polyphenol content in olive oil.
