Which omega-3 supplement came out best in the test?

Romega Omega-3 is named best in test. It provides 500–1000 mg omega-3 per daily dose with 340–680 mg DHA from herring roe oil and fish oil, and scores 15/15 for DHA, 5/5 for excipients and 5/5 for capsule size.

Can vegetarians and vegans get enough omega-3?

Yes. The article states it is possible to meet the need for omega-3 with plant-based alternatives, especially through algal oil, which contains DHA. ALA from plant sources must first be converted to EPA and DHA, and because that conversion is limited, a higher intake is required.

Why do omega-3 supplements contain antioxidants?

Omega-3 oils are prone to oxidation. Antioxidants such as vitamin E and astaxanthin help protect the fatty acids from going rancid and preserve the quality of the oil.

Key takeaways

- A daily intake of around 250 mg of EPA and DHA combined is enough to maintain normal heart, brain and vision function.

- Romega Omega-3 is rated best in test, scoring full marks for DHA, excipients and capsule size, with lower EPA content than most fish oils as its main drawback.

- Omega-3 in fish oil is bound to triglycerides, while krill oil binds it to phospholipids, a form the article says can be absorbed more effectively.

- ALA from flaxseed, chia, walnuts and plant oils must be converted to EPA and DHA in the body, and because that conversion is limited, plant sources require a higher intake.

We give you an overview of the best omega-3 supplements on the market in 2026.

Why does the body need omega-3 from food or supplements?

Omega-3 is an essential fatty acid that the body does not produce itself, and therefore must be obtained through diet or supplements. For many, a supplement is a simple and affordable way to ensure a consistent intake, especially if you eat little fish.

At the bottom of the article, you can read more about how the products were evaluated, and what omega-3 fatty acids actually do in the body.

How were the omega-3 supplements scored?

The supplements are evaluated based on their content of omega-3 and the fatty acids EPA and DHA, as well as ingredients, user-friendliness, and price.

Omega-3 – total content (40) Evaluated based on how much omega-3 the product provides per daily dose. This indicates how concentrated the oil is and how much you actually consume per intake. A high content makes it easier to meet the needs without having to take many capsules.

EPA (15) Evaluated based on the content of EPA per daily dose. EPA is particularly important for heart health and for reducing inflammatory conditions in the body, and a high level therefore provides better effects.

DHA (15) Evaluated based on the content of DHA per daily dose. DHA is important for the brain, vision, and the nervous system, and products with high content score better.

Antioxidants (10) Evaluated based on whether the product contains antioxidants such as vitamin E or astaxanthin. Omega-3 oils are prone to oxidation, and antioxidants help protect the fatty acids from rancidity and preserve quality.

Excipients and Composition (5) Evaluated based on what extra substances the product contains and what function they have. The addition of vitamin D is a plus, as many do not get enough through diet and sunlight.

In krill oil, omega-3 is bound to phospholipids instead of triglycerides. Phospholipids are part of cell membranes, and this form allows the fatty acids to be absorbed more quickly in the body.

Some products also contain phosphatidylcholine and choline. Phosphatidylcholine is a type of phospholipid that is part of cell membranes, while choline is necessary for normal cell function and fat metabolism.

Products that also contain fatty acids such as SDA or ketoleic acid can score higher, as these can contribute to the conversion to EPA in the body.

At the same time, the ingredient list is evaluated as a whole. Products with few and relevant ingredients score better than those with many additives without a clear function.

Taste / Aftertaste (5) The capsules are tested both by swallowing and chewing. Products with little fish taste or unpleasant aftertaste score highest.

Size of Capsules (5) Evaluated based on how easy the capsules are to swallow. Large capsules can be a challenge for many, and therefore score lower.

Price (5) Evaluated based on price per daily dose compared to the content of EPA and DHA. Products that provide a lot of content for the money score best.

What are omega-3 fatty acids?

Omega-3 fatty acids are polyunsaturated, essential fatty acids that the body does not produce itself.

They must therefore be obtained through diet or supplements. A daily intake of around 250 mg EPA and DHA is sufficient to maintain normal function of the heart, brain, and vision.

These fatty acids are part of cell membranes and are important for several processes in the body, including signaling molecules that affect inflammation levels and immune response. They also play a central role in the normal development and maintenance of brain, vision, and heart function.

Omega-3 is particularly known for its effect on triglycerides in the blood, which can contribute to better heart health.

Omega-6 is usually consumed in sufficient amounts through a regular diet, from sources such as vegetable oils, nuts, and grain products.

What is the difference between EPA, DHA and ALA?

The most important omega-3 fatty acids are EPA (eicosapentaenoic acid), DHA (docosahexaenoic acid) and ALA (alpha-linolenic acid).

EPA and DHA are mainly found in fatty fish, cod liver oil and algae. These fatty acids are directly available to the body and are the most relevant in supplements.

Is fish oil or krill oil better absorbed?

Omega-3 from fish oil is bound to triglycerides, while krill oil is bound to phospholipids. Phospholipids are part of cell membranes, and this form can provide a more effective absorption of the fatty acids.

Can you get enough omega-3 from plant sources?

ALA is found in plant sources such as flaxseeds, chia seeds, walnuts, and plant oils. For the body to utilize ALA, it must first be converted to EPA and DHA, but this conversion is limited.

Therefore, a higher intake from plant sources is required to achieve the same levels as from marine sources.

It is still possible to meet the need for omega-3 with plant-based alternatives, especially through algal oil which contains DHA.

Which other substances can an omega-3 supplement contain?

Some omega-3 products also contain other fatty acids or substances that can affect how omega-3 is utilized in the body.

SDA (stearidonic acid) is an omega-3 fatty acid that is further converted to EPA in the body. It is found in certain plants and marine sources.

DPA (docosapentaenoic acid) is an omega-3 fatty acid that acts as an intermediary between EPA and DHA. It is found in fish oil and other marine sources, and is involved in processes related to inflammation, heart and joint health, as well as cell function.

Ketoleic acid is a marine fatty acid that may contribute to increased conversion of other omega-3 fatty acids to EPA.

Policosanol is found in the outer layer of certain cereal plants such as corn, barley, rice, oats, wheat, and millet. It is this that provides a protective and hard waxy layer on the plant.

Policosanol has been shown to have a good effect on cholesterol, by lowering the bad (LDL) cholesterol and increasing the good (HDL) cholesterol. [Studies](https://www.sciencedirect.com/topics/medicine-and-dentistry/policosanol) have shown effects of 10-20 mg of policosanol per day.

Omega-3 supplements are added with antioxidants, which are meant to ensure that the fatty acids remain fresh and do not become rancid. These are antioxidants such as Vitamin E and Astaxanthin.

How much fish should you eat each week?

Health authorities recommend an intake of 300–450 grams of fish per week, of which at least 200 grams should be fatty fish such as salmon, trout, mackerel, or sardines.

Omega-3 supplements can be a good alternative to meet the needs, especially for those who eat little fish.
