The best olive oil for cholesterol is a high-polyphenol extra virgin olive oil above the 250 mg/kg EFSA threshold. A meta-analysis of 26 randomized controlled trials found that high-polyphenol EVOO significantly reduced oxidized LDL, lowered total cholesterol by 4.5 mg/dL, and raised protective HDL by 2.37 mg/dL compared to low-polyphenol olive oil (George et al., Nutrients, 2019). The more useful finding is that concentration beats volume. A 2025 Greek randomized trial in 50 hyperlipidemic patients found that 8g/day of a 1,021 mg/kg oil produced greater total cholesterol reductions than 20g/day of a 414 mg/kg oil, with both groups taking the same total daily polyphenol dose. What matters is clearing the threshold with an oil whose number you can actually verify, then taking it consistently.
Key Facts: Olive Oil and Cholesterol
- Meta-analysis of 26 RCTs: High-polyphenol EVOO reduced oxidized LDL (SMD −0.44), lowered total cholesterol by 4.5 mg/dL, and raised HDL by 2.37 mg/dL vs low-polyphenol oil (George et al., Nutrients, 2019)
- 2025 Greek RCT (n=50): 8g/day of 1,021 mg/kg EVOO outperformed 20g/day of 414 mg/kg EVOO for total cholesterol at the same total polyphenol dose (General Hospital of Messinia, Kalamata)
- 2023 meta-analysis (10 RCTs): High-polyphenol olive oil significantly increased HDL and reduced LDL, with the strongest effects in the 320–600 mg/kg tertile (Jabbarzadeh-Ganjeh et al., Nutrients, 2023)
- The LDL oxidation trial: 25 mL/day of a 366 mg/kg oil reduced LDL oxidation, while the same volume of a 2.7 mg/kg oil increased it (Castañer et al., AJCN, 2012)
- EFSA health claim: Olive oil polyphenols "contribute to the protection of blood lipids from oxidative stress," requiring roughly 250 mg/kg (EFSA, 2011)
- HDL function, not just levels: Polyphenol-rich EVOO improves HDL's ability to remove cholesterol from arteries (cholesterol efflux capacity), not just the HDL number on a blood test
Does Polyphenol Content Actually Affect Cholesterol?
Yes, and the evidence is unusually consistent. Multiple randomized controlled trials show that polyphenol concentration, rather than just the presence of olive oil in the diet, drives the cholesterol improvements.
The 2025 Greek trial (General Hospital of Messinia, Kalamata, n=50 hyperlipidemic patients plus 20 healthy controls) directly compared two EVOOs from the same Koroneiki olive variety at different polyphenol concentrations. One group received 20g/day of a 414 mg/kg oil, the other 8g/day of a 1,021 mg/kg oil, with both consuming the same total daily polyphenol dose of roughly 8.3 mg. After four weeks, the higher-concentration group showed a significantly greater reduction in total cholesterol (p=0.045). Both groups improved on HDL and lipoprotein(a).
The 26-trial meta-analysis (George et al., Nutrients, 2019) found that compared to low-polyphenol olive oil, high-polyphenol EVOO significantly reduced oxidized LDL (SMD −0.44, p=0.01), lowered total cholesterol by 4.5 mg/dL (p<0.0001), and raised HDL by 2.37 mg/dL (p=0.02).
The 2023 meta-analysis (Jabbarzadeh-Ganjeh et al., Nutrients, 2023, 10 RCTs) confirmed that daily olive oil polyphenol consumption increased HDL and slightly reduced LDL, with the strongest effects in the 320 to 600 mg/kg tertile.
The practical read: a grocery store EVOO at 150 mg/kg provides monounsaturated fat benefits but won't deliver the polyphenol-specific effects these trials measured. Clearing the 250 mg/kg EFSA threshold is the meaningful line, and the trial evidence clusters in the 300 to 600 mg/kg range rather than at the extreme top of the market.
Which Olive Oil Is Best for Lowering Cholesterol?
Polyphenol content, not brand name or price, determines an olive oil's impact on cholesterol. What complicates the shopping decision is that most brands publish either an unverifiable number or none at all, so the column worth reading is where the figure came from.
| Brand | Polyphenols (mg/kg) | Clears EFSA Threshold? | Source of Figure | Origin | Price/oz |
|---|---|---|---|---|---|
| The Governor (Greece) | 1,377 | Yes | Producer NMR analysis | Corfu, Greece | ~$3.00 |
| Cobram Estate Robust | 500–900 | Yes | Brand-published range | Australia | ~$1.00 |
| Papa Vince (Sicily) | 515 | Yes | Brand-published, HPLC claimed | Santa Ninfa, Sicily | ~$1.80 |
| Hoji Blanca (Spain) | 306 ± 21 | Yes | Named accredited lab, method and sample ref. published | Andalusia, Spain | $1.47/pkt |
| Terra Delyssa (Tunisia) | 200+ | Borderline | General brand claim | Tunisia | ~$0.50 |
| Kirkland Organic (Costco) | 200–300 (est.) | Borderline | Not published | Blend | ~$0.36 |
| Bertolli | ~182 (est.) | No | Not published | Multi-country | ~$0.40 |
EFSA threshold: roughly 250 mg/kg, derived from 5 mg hydroxytyrosol and derivatives per 20 g daily serving. Hoji's figure is total phenolic compounds by liquid chromatography under COI/T.20/Doc. nº 29 Rev. 2 at Indlab (ENAC Nº 1089/LE2141), sample ref. 202515396, 19 November 2025. Estimates marked (est.) are industry testing patterns rather than brand disclosures. Disclosure: Hoji Real publishes this article and appears in the table. All brands are assessed on the same criteria. For the full 12-brand ranking, see healthiest olive oil brands ranked.
Two things are worth noticing in that table. The oils at the top carry the biggest figures and the thinnest sourcing, since none names the laboratory or the batch. And the cheapest options don't publish anything, so a shopper choosing on cholesterol has nothing to work with. Clearing the threshold with a number you can trace to a specific lab, method, and harvest is a different proposition from clearing it on a brand's word.
How Does Olive Oil Improve Cholesterol?
Olive oil affects cholesterol through three distinct mechanisms, and only two of them require polyphenols.
1. Oleic acid
Any olive oil. Monounsaturated fat (~73% of total) modestly reduces LDL when it replaces saturated fat. A generic substitution effect.
2. LDL oxidation
High-polyphenol only. Polyphenols prevent LDL particles from oxidizing, which is the step that makes them inflammatory.
3. HDL function
High-polyphenol only. Improves how well HDL particles clear cholesterol from artery walls, not just the number on a test.
Oleic acid is the mechanism every olive oil provides, regardless of quality. It's real and it's modest.
LDL oxidation prevention is the critical one. Atherosclerosis is driven by oxidized LDL rather than total LDL, since oxidized particles become inflammatory and trigger plaque formation in arteries. Olive oil polyphenols, particularly hydroxytyrosol, directly prevent that oxidation. A crossover trial (Castañer et al., American Journal of Clinical Nutrition, 2012, n=18) found that 25 mL of a 366 mg/kg oil reduced LDL oxidation, while the same amount of a 2.7 mg/kg oil increased it.
HDL function improvement goes beyond the number on a blood test. A crossover trial (Farràs et al., Journal of Nutritional Biochemistry, 2013, n=13 pre-hypertensive and hypertensive patients) found that a 961 mg/kg oil upregulated genes involved in cholesterol efflux, the process by which HDL removes cholesterol from artery walls.
How Much Olive Oil Should You Take for Cholesterol?
The 2025 Greek trial gives the practical answer: concentration matters more than volume. Patients taking 8g/day (roughly 2 teaspoons) of a 1,021 mg/kg oil saw better cholesterol outcomes than those taking 20g/day (about 1.5 tablespoons) of a 414 mg/kg oil.
- Minimum effective dose: 20g/day (~1.5 tablespoons) of EVOO above 250 mg/kg, which is the EFSA reference serving and threshold
- Where the trial evidence is strongest: 25–40 mL/day of an oil in the 300–600 mg/kg range, which covers the Castañer, George, and Jabbarzadeh-Ganjeh findings
- Lower-volume approach: As little as 8g/day of an ultra-high-polyphenol oil may be sufficient, based on the 2025 Greek trial
- Calories: One tablespoon is roughly 120 calories. Factor it in by replacing other fats rather than adding on top
Consistency matters as much as either number. Every one of these trials ran for weeks with daily consumption, so an oil you take every morning does more than a more concentrated one you stop using. For guidance on timing, see our guide to the best time to take olive oil.
Is Cooking with Olive Oil Good for Cholesterol?
Yes, with a nuance. Cooking with olive oil provides the oleic acid benefit, which modestly improves cholesterol when olive oil replaces butter or seed oils. Cooking at high temperatures for extended periods does degrade some polyphenols, though, reducing the LDL oxidation protection and HDL function effects.
For maximum benefit, use olive oil both ways: cook with it and consume it raw. A drizzle of raw high-polyphenol EVOO on finished dishes and salads, or taken as a daily shot, delivers the full polyphenol spectrum without heat-related degradation.
Can Olive Oil Replace Statins?
No, and any article suggesting otherwise is being irresponsible. Olive oil is a dietary intervention with meaningful cholesterol benefits, operating on different mechanisms and at different magnitudes than statin medications.
Statins reduce LDL cholesterol by 30 to 50% by inhibiting HMG-CoA reductase. High-polyphenol olive oil reduces total cholesterol by roughly 4.5 mg/dL and significantly reduces oxidized LDL. Those are complementary effects rather than replacements. The PREDIMED trial (Estruch et al., NEJM, 2018, n=7,447) showed olive oil reduced cardiovascular events by 30%, which is comparable to statin outcomes but through different pathways.
If your doctor has prescribed statins, continue taking them. Adding high-polyphenol olive oil provides additional protection through the LDL oxidation and HDL function mechanisms statins don't directly address. The two approaches are additive.

Frequently Asked Questions
What is the best olive oil for lowering cholesterol?
An extra virgin olive oil above the 250 mg/kg EFSA threshold, with a harvest date within 12 months and a polyphenol figure you can trace to a named lab and method. A meta-analysis of 26 RCTs found high-polyphenol EVOO significantly reduced oxidized LDL, lowered total cholesterol by 4.5 mg/dL, and raised HDL by 2.37 mg/dL compared to low-polyphenol olive oil. The trial evidence is strongest in the 300 to 600 mg/kg range.
Does olive oil raise or lower cholesterol?
Olive oil lowers total cholesterol and LDL while raising protective HDL, and the magnitude depends on polyphenol content. A 2023 meta-analysis found the strongest cholesterol effects in the 320 to 600 mg/kg tertile. Grocery store EVOOs at 100 to 200 mg/kg provide modest benefits from oleic acid but not the polyphenol-specific effects on LDL oxidation.
How much olive oil per day for cholesterol?
Research supports 1.5 to 3 tablespoons (20 to 40 mL) daily of EVOO above 250 mg/kg. A 2025 Greek trial showed that as little as 8g/day of an ultra-high-polyphenol oil improved cholesterol more effectively than 20g/day of a lower-polyphenol oil at the same total polyphenol dose, so concentration matters more than volume.
Is extra virgin olive oil better for cholesterol than regular olive oil?
Yes. Extra virgin olive oil retains the polyphenols that drive LDL oxidation prevention and HDL function improvement, while refined olive oil ("pure" or "light") has been stripped of them during processing. A crossover trial found that a 366 mg/kg oil reduced LDL oxidation while the same amount of a 2.7 mg/kg oil increased it (Castañer et al., AJCN, 2012, n=18).
Can olive oil lower cholesterol without medication?
For mildly elevated cholesterol, high-polyphenol olive oil combined with a Mediterranean diet pattern can produce meaningful reductions, and the PREDIMED trial showed a 30% reduction in cardiovascular events. For significantly elevated cholesterol, olive oil should complement prescribed medications rather than replace them. Discuss dietary changes with your doctor, especially if you're on statins or other lipid-lowering medications.
Does the type of olive oil matter for cholesterol?
Critically. A 2025 randomized trial comparing two EVOOs at different polyphenol concentrations found the higher-concentration oil produced significantly better cholesterol outcomes even at a lower daily dose. EFSA requires roughly 250 mg/kg to claim protection of blood lipids from oxidative stress, and most grocery store EVOOs fall below it or publish nothing at all.
