You've probably heard it a thousand times by now. Drizzle it on your salad. Sauté your kale in it. Heck, some "health gurus" are even out here taking shots of the stuff before breakfast. We treat extra virgin olive oil like a liquid miracle, and for the most part, it actually lives up to the hype. But when people start asking does olive oil have omega 3, the answer gets a little murky. It’s not a simple yes or no because, honestly, the amount matters way more than the mere presence of the nutrient.
Olive oil is the backbone of the Mediterranean diet. That’s a fact. But if you’re relying on your bottle of Bertolli or that fancy estate-bottled peppery stuff to hit your daily brain-boosting fatty acid goals, you’re likely going to fall short.
Most people confuse "healthy fat" with "omega-3 source." They aren't the same thing.
The Short Answer: Yes, But There’s a Catch
So, does olive oil have omega 3? Yes. It does. Specifically, it contains Alpha-Linolenic Acid, or ALA. This is the plant-based version of omega-3.
But don't get too excited just yet.
The concentration is actually pretty low. In a typical tablespoon of extra virgin olive oil (EVOO), you’re looking at roughly 100 milligrams of ALA. To put that in perspective, the National Institutes of Health (NIH) suggests adult men need about 1,600mg a day and women need 1,100mg. You would have to drink over half a cup of oil to get close. Please don't do that. Your digestive system would never forgive you.
Understanding the Fat Profile of Your Pantry Staple
To understand why olive oil isn't an omega-3 powerhouse, we have to look at what it actually is. Olive oil is primarily Oleic acid. That’s an Omega-9.
Omega-9s are monounsaturated fats. They are stable. They are great for your heart. They don't oxidize as easily as the polyunsaturated fats (PUFAs) found in seed oils. About 73% of olive oil is this monounsaturated goodness. That’s the real reason it’s a "superfood." It displaces the nasty, pro-inflammatory fats in your diet.

But omega-3s? They are a tiny fraction. Usually less than 1% of the total fatty acid composition.
Why the ALA in Olive Oil Isn't Enough
Here is where it gets technical but important. ALA is a "short-chain" fatty acid. Your body is a bit of a snob—it prefers "long-chain" omega-3s like EPA and DHA. Those are the ones you find in fatty fish like salmon or sardines.
Your liver has to convert ALA into EPA and DHA to really use it for brain health and reducing systemic inflammation.
The conversion rate is terrible.
Scientific studies, including those published in The American Journal of Clinical Nutrition, suggest that less than 5% of ALA gets converted to EPA. For DHA? It’s often less than 0.5%. So, that tiny bit of omega-3 in your olive oil? By the time your body processes it, there’s barely anything left for your brain cells to work with.
Does Olive Oil Have Omega 3 Compared to Other Oils?
If you’re looking for omega-3s in the oil aisle, olive oil is actually a middle-of-the-road player. Flaxseed oil is the king of ALA, boasting roughly 7,000mg per tablespoon. Walnut oil is another heavy hitter.
Even canola oil has more omega-3 than olive oil.

Wait. Stop.
Does that mean canola is better? Absolutely not. Canola oil is highly processed, often hexane-extracted, and carries a high load of omega-6 fatty acids. This brings us to a crucial point about the "Omega Balance."
The Omega-6 to Omega-3 Ratio
The modern Western diet is a disaster because we eat way too much omega-6. It’s in everything—soybean oil, corn oil, processed snacks. While we need some omega-6, we usually consume it at a ratio of 20:1 compared to omega-3. This imbalance is linked to chronic inflammation.
Olive oil is a hero here.
Even though it doesn't have a ton of omega-3, it is naturally low in omega-6. By using it, you aren't adding fuel to the inflammatory fire. It helps maintain a better overall ratio in your body. It's more about what it doesn't do (cause inflammation) than what it does do (provide omega-3).
The Quality Factor: Not All Olive Oils Are Equal
If you buy the "Light" or "Refined" olive oil in the plastic jug, you’re getting even less nutritional value. Heat and chemical processing strip away the polyphenols and can degrade the fragile omega fatty acids.
Always look for Extra Virgin (EVOO). Real EVOO is basically fruit juice. It’s pressed without heat. This preserves the minor amount of ALA that is present. Look for a harvest date on the bottle. If it's more than two years old, those delicate fats are likely rancid anyway. Freshness is everything.

You can tell it’s high quality if it stings the back of your throat. That "burn" is oleocanthal, a potent anti-inflammatory compound that mimics the effect of ibuprofen. It has nothing to do with omega-3, but it’s a huge reason why the oil is healthy.
Misconceptions About Cooking and Fat Breakdown
There’s this persistent myth that you can't cook with olive oil because the "omegas will turn toxic."
It’s mostly nonsense.
While omega-3s are heat-sensitive, the amount in olive oil is so small, and the protective antioxidants (polyphenols) are so high, that EVOO actually holds up surprisingly well under normal cooking temperatures. Research from Food Chemistry has shown that high-quality EVOO remains stable even after hours of deep frying. The monounsaturated fats act like a shield for the tiny bit of omega-3 inside.
Where Should You Get Your Omega-3 Instead?
If olive oil isn't the answer to your omega-3 needs, what is?
- Cold-water fatty fish: Salmon, mackerel, anchovies. These give you the EPA and DHA directly. No conversion needed.
- Algae oil: The vegan alternative to fish oil. It’s where the fish get their omega-3 from in the first place.
- Chia seeds and Flaxseeds: Great for ALA, though you still deal with the poor conversion rate.
- Grass-fed beef: Surprisingly, meat from cows that actually eat grass has a much better omega-3 profile than grain-fed beef.
Actionable Steps for a Better Fat Balance
Stop worrying about whether your olive oil is providing enough omega-3. It isn't. Use it for what it's good at: providing stable monounsaturated fats and massive amounts of antioxidants.
Here is how you actually optimize your intake:
- Keep using EVOO as your primary fat. Use it for dressings, low-to-medium heat cooking, and finishing dishes. It keeps your omega-6 intake low.
- Add a dedicated Omega-3 source. Eat two servings of low-mercury fatty fish per week. If you're plant-based, take a high-quality algae-based DHA/EPA supplement.
- Check your labels. If a "Healthy Olive Oil Mayonnaise" lists soybean oil as the first ingredient, put it back. You're just buying cheap omega-6 filler.
- Store it right. Light and heat are the enemies. Keep your olive oil in a dark glass bottle in a cool cupboard, not on the counter next to the stove.
Olive oil is a foundational health food, but it is not a complete nutritional package. It works best when it's part of a team. It provides the "shield" by being low-inflammatory, while fish or algae provide the "sword" with high-dose EPA and DHA.
Stop looking for a one-stop-shop in a single bottle. Real nutrition is about the synergy of different whole foods working together. Buy the best olive oil you can afford, enjoy the flavor, and get your omega-3s from the sea.
