Best Omega-3 Supplements in Canada (2026) | Fish Oil Comparison Guide

This is a science-based comparison guide for those seeking the optimal omega-3 supplement in Canada. The comparison consists of seven of Canada's highest-selling omega-3 supplements, analysed side by side across key formulation metrics to determine which are the best options for consumers. 

Comparing omega-3 supplements can be really tough, as brands often state multi-capsule dosage claims on the front, such as “triple strength,” while obscuring how much actual omega-3 is in the product. Here, we cut through the marketing jargon and look directly at the real data to show which are clearly the best products.

The brands analysed are:

• Webber
• Jamieson
• VitaSave
• Thrive
• Mav Nutrition
• Sports Research
• Nutra Champs

The categories analysed are:

• Total EPA & DHA per Capsule
• Omega-3 Concentration
• Chemical Form of Omega-3
• Third Party Testing
• Cost per Gram of EPA & DHA
  

Overall Results

If you're interested in looking at the full dataset for this analysis, which includes the raw data, the scoring key, and additional information for all the products analysed here, see this datasheet. This article summarises this data in an easy-to-read format.

Introduction: How much Omega-3 do we need?

Before the main analysis, it’s important to understand how much Omega-3 we actually need for optimal health support, as this gives context to the analysis of the supplements. For a deep dive, I’ve written two entire articles on this (1) (2) - here I'll briefly summarize the scientific literature.

Optimal Omega-3 intake is often studied by measuring people's Omega-3 index, which is the percentage of our red blood cell membranes that consists of Omega-3 fats, and reflects long-term omega-3 intake. The Omega-3 index is a validated biomarker, strongly associated with cardiovascular risk. I.e, the higher Omega-3 index, the lower the risk of cardiovascular disease (3) (4). 

A daily intake of 250–500 mg of combined EPA and DHA is commonly cited as the minimum amount required to support cardiovascular health in healthy individuals (5) (6) (7) (8). However, this is far below what is required to optimize the Omega-3 index. Instead, research shows that 1500–2500 mg of EPA & DHA per day is required for optimal cardiovascular support (7) (8) (9), and currently, only 3% of Canadians meet this target (10).

Non-Scored Data

Brand Country of Origin

This is where each company is based and manufactures the product. The actual fish in the brands is sourced from all over the world.Nutra Champs is a Canadian brand, but manufactures in the US which is why there are two flags above. 

Cost per 120 capsules

Each brand uses different unit sizes, so here I have normalised them all to cost per 120 capsules. Note that there is a wide range in cost, but that is because they are very different products, as you will later see. 

This is not scored towards the final results, as the products differ significantly. Instead, cost per gram of EPA and DHA is scored later which better represents true value.

Main Analysis

Total EPA & DHA per Capsule

This is one of the most important factors in choosing an omega-3 supplement, as EPA and DHA are the active ingredients. In other words, EPA and DHA are the actual omega-3 fats. Below is the EPA & DHA per single capsule of each product.

Of the brands analysed, Nutra Champs, Mav Nutrition, Sports Research, and Thrive are the true high potency options, hence their higher price tag over the budget options. 

As already mentioned, brands often list a 3-capsule value, “triple strength,” on the front of the label, not the amount per capsule. Take Webber, VitaSave, Mav Nutrition, and NutraChamps, for example. They all state 1000–3000 mg EPA/DHA on the front, but you actually need three capsules to achieve this. 

Adding further confusion, the brands also state the total fish oil on the front, often far larger than the total EPA and DHA, to imply this is the active amount. Take Webber and Mav Nutrition, for example. The largest text on the front label is 1000 mg and 3600 mg, but this is just the total fish oil, not the total omega-3.

Capsules required for optimal health support

As mentioned in the introduction, research consistently shows that 1500–2250 mg daily is required to raise the Omega-3 index to the optimal range of 8%+ (7) (8) (9). Supplemental Omega-3, although highly bioavailable, is not as bioavailable as oily fish itself (11). Therefore, it’s best to aim for the upper end of 2250 mg per day, particularly if your weekly oily fish consumption is low.

This is how many capsules per day of each brand to provide 2250 mg+ of EPA and DHA.

Omega-3 Concentration

Omega-3 concentration refers to the actual percentage of the total fish oil in the capsule that is EPA and DHA. For example, a 1200 mg capsule with 600 mg combined EPA and DHA would be 50% concentration. This is included because higher concentrations offer a more potent product, and because concentration is associated with improved bioavailability, particularly in ethyl ester forms (see this article to learn more). 

Chemical Form of Omega-3

Omega-3 supplements can come in various chemical forms, but the two most common forms are Ethyl Ester (EE) and Triglyceride (TG). There are various opinion pieces online stating that TG is more bioavailable than EE. While there may be some subtle bioavailability differences between TG and EE, if EE is not consumed alongside food, they are small and largely not supported by the available research. To delve into comparing the the various chemical forms, read this article.

That being said, as there is some evidence suggesting TG may be slightly more bioavailable than EE, I have awarded an extra point for TG over EE. Furthermore, as EE bioavailability depends on its EPA and DHA concentration, EE with over 60% concentration is awarded 7 points, while <60% is awarded 6 points.To gather this information, I reached out to every company, as it is not often stated on the label. VitaSave was unable to answer the question, which is why the chemical form is not stated above and thus is awarded 5 points.

Third Party Testing

Alongside EPA and DHA content, third-party testing is one of the most important factors when choosing an omega-3 supplement, as it verifies potency, oxidation, heavy metal content, and contaminants. To obtain this information, I reached out to every brand over the course of several weeks, requesting testing results.Webber and Thrive both conduct full panel third-party testing which includes testing for potency, oxidation, heavy metal content, and contaminants. Nutra Champs also test for all of the above, except for potency. All three of these brands share their testing results upon request. Our third-party testing results are available here. 

As someone with a passion for nutrition science, I find it slightly ironic that, given research is generally grounded in transparency and science, a brand called Sports Research does not disclose its testing results or inform customers what it tests for.

Cost per Gram of EPA & DHA

This is the best indicator of value, as it represents the actual cost for the active ingredient you are receiving. To calculate this, I summed the total EPA and DHA in an entire unit of product and then divided it by the unit cost.
