Omega-3 Supplement Comparison
Label data as of July 2026
Read this first. This chart lists what each company publishes on its own Supplement Facts panel. It is not a ranking and there is no winner. I have not tested any of these products, and nothing here is a recommendation to buy or avoid anything.
My disclosures. I am an independent affiliate or distributor for one or more companies listed on this page and I earn income when people order through me. I have included those products on the same terms as every other product, with no special treatment and no pick. You should still weigh my involvement when you read this.
These numbers expire. Formulas, prices, and certifications change constantly. Always read the current panel on the bottle in your hand before you buy. Prices are approximate US figures and vary by retailer, subscription, and promotion.
Why I bother with this at all
Of everything I take, omega-3 is the one I would keep if I had to give up the rest.
Here is the short reason. There are two fats your body cannot make. It has to get them from food. One is an omega-6 and one is an omega-3, and almost everyone eating a modern diet gets a great deal of the first and very little of the second.
That matters because the two work from the same pool. They compete for the same enzymes and they sit in the same cell membranes. When one crowds out the other, the balance tips.
What omega-3s actually do, in plain terms:
- They are structural. DHA is one of the most abundant fats in your brain and in the retina of your eye. Your body is not using it for fuel. It is building with it.
- They sit in every cell membrane you have. Membranes made with these fats behave differently than membranes made without them, and every cell in your body has one.
- They help inflammation finish. This is the part most people have backwards. Inflammation is supposed to happen. It is how you heal. The problem is when it never switches off. Your body makes specialized molecules out of EPA and DHA that signal the end of an inflammatory response. Without enough raw material, that signal is quieter.
Nothing on this page treats or cures anything, and I want to be careful about that. What I can tell you is that omega-3 is one of the few things where the research is deep, the mechanism makes sense, and most people are genuinely running low. That combination is rarer than the supplement aisle would have you believe.
We have tried a good number of the products on this list over the years, in this house, in different seasons and for different people. That is part of why I keep the chart.
One thing to know before you read the chart
Most omega-3 supplements are plain fish oil, pressed from the flesh of small oily fish like anchovy, sardine, and mackerel. That is the majority of what is on this list.
A few are cod liver oil. Those come from the fish's liver, which is where it stores fat-soluble vitamins, so they carry naturally occurring vitamin A and D along with the omega-3s. That changes how you dose them, and there is a note at the bottom of this page explaining why.
The source column tells you which is which.
The comparison
Comparing omega-3 products is hard because the front of the bottle rarely tells you what you need to know. The only numbers that matter much are how much real EPA and DHA you get in one serving, and whether an outside lab has verified it.
So that is what this chart shows. Sort by any column. Use the filters to narrow it down.
| Product ↕ | Channel ↕ | Source & form ↕ | EPA+DHA / serving ↕ | Serving ↕ | Outside testing named ↕ | Approx. price / serving ↕ |
|---|
On a phone, scroll the table sideways to see every column.
How to use this
Find the EPA+DHA column and check the serving size next to it. A product listing 2,400 mg across four capsules and one listing 1,000 mg in a single capsule are closer than they look, and the four-capsule bottle empties twice as fast.
Then look at the testing column. A named outside body with a searchable registry means someone other than the manufacturer verified the contents. "None named" does not mean a product is bad. It means you are taking the company's word for it.
Where a row says EPA and DHA are not broken out, that is what the published panel does. Some products list only a combined omega-3 total, which can include ALA from plant oils. ALA is a fine thing to eat and it is not the same as EPA and DHA.
A note on cod liver oil
This applies to the handful of liver oils on the list, not to the fish oils, so I have kept it down here.
Cod liver oil is a traditional food and people have done well on it for a very long time. The vitamins that come with it are part of why. But the liver is where a fish concentrates its fat-soluble vitamins, and that has one practical consequence worth understanding: you cannot simply take more of it when you want more EPA and DHA.
Why the ceiling on vitamin A is worth respecting. Preformed vitamin A, the retinol kind found in animal foods and liver oils, has a tolerable upper intake level of 3,000 mcg RAE a day for adults, which is about 10,000 IU. Unlike a water-soluble vitamin, the excess does not simply rinse out. It accumulates.
That limit applies to women of childbearing age, pregnant women, and nursing mothers at the same level, and pregnancy is where it matters most. The upper limit was set on the basis of birth defect risk. European food safety guidance advises women who are pregnant or planning to become pregnant not to eat liver products at all.
The real risk is stacking, not the spoonful. A typical teaspoon of cod liver oil sits well within the limit on its own. The trouble comes from adding things up. Cod liver oil plus a multivitamin containing retinol plus liver at dinner can reach the ceiling faster than anyone intends. If you are pregnant, nursing, or might become pregnant, talk with your doctor before taking any liver oil, and total the preformed vitamin A across everything you take.
So the practical rule. Taking a modest daily amount for the vitamins that come with it, cod liver oil is a good traditional food. If your goal is to move your omega-3 numbers, and especially if you need a higher dose to do it, a plain fish oil from the flesh lets you take what you need without a vitamin A ceiling in the way.
