Top 5 Algal Oil Supplements in Canada (2026): Vegan EPA + DHA Compared
Published on Thursday, January 1, 2026
Algal oil is the one omega-3 source that skips the fish entirely: the EPA and DHA in fish oil originate in marine microalgae, and algal oil supplements harvest them directly. The practical question is not whether algal oil works but how much EPA and DHA you actually get per serving, because the labels on this page vary widely. Ovega-3 declares 500 mg of omega-3s per serving, split 135 mg EPA and 270 mg DHA. Spectrum Essentials Vegan Ultra Omega-3 declares 165 mg EPA and 330 mg DHA in a two-softgel serving, plus 25 mcg of vegan vitamin D2. Nested Naturals is a DHA-only algal formula with no EPA declared on the label. Two things are worth checking before you buy in Canada: the serving size (some of these figures are per two softgels, not per capsule), and whether the bottle carries an eight-digit NPN, since several algal oil brands are formulated for the US market and reach Canadian buyers through marketplace sellers. Below, each option is compared on the numbers printed on its own label.
Top Picks Summary

It features a potent DHA concentration that supports brain and eye health without any fishy aftertaste. This product is meticulously crafted to meet the highest quality standards, ensuring it is free from heavy metals and toxins commonly found in fish-derived oils. Freshfield's commitment to vegan and sustainable practices makes this supplement an excellent choice for health-conscious consumers.
Nested Naturals Vegan Omega 3
Nested Naturals Vegan Omega 3 is a plant-based supplement built on algal oil, with the newer formula pairing algal DHA with Ahiflower seed oil. It is a DHA-focused product: the label declares DHA but does not declare EPA, so it suits buyers whose priority is DHA rather than a balanced EPA-and-DHA dose. The formula is free from GMOs, gluten and artificial additives, and Nested Naturals publishes its sourcing, which is part of why the product has held its following.
Spectrum Essentials Vegan Ultra Omega-3 EPA+DHA
Spectrum Essentials Vegan Ultra Omega-3 EPA+DHA is the highest-DHA option on this page. A two-softgel serving declares 165 mg of EPA and 330 mg of DHA, both from marine algal oil, plus 25 mcg of vegan vitamin D2 — a useful pairing in Canada, where winter vitamin D intake is a common gap. The oil is stabilised with rosemary extract, tocopherols and ascorbyl palmitate. Note that the softgel shell is carrageenan-based, which matters if you avoid carrageenan.
Ovega-3 Omega-3s EPA+DHA
Ovega-3 is the most straightforward label on this page: one serving declares 500 mg of total omega-3s, split 135 mg of EPA and 270 mg of DHA, all from marine algae rather than fish. It is gluten free, soy free and free of the allergens associated with fish oil, and there is no fishy aftertaste because there is no fish in it. Sold in 60, 80 and 90 count bottles, with a separate mini-softgel version that uses a two-softgel serving — check which one you are ordering.
The strongest algal oil supplements state EPA and DHA in milligrams per serving, name the serving size clearly, and disclose the softgel shell material. All five here are plant-based and fish-free; they differ mainly in whether they deliver both EPA and DHA or DHA alone, and in how many softgels a stated dose requires.
How to read an algal oil label
Algal oil supplements differ less in quality than in what they actually declare per serving. These are the label details that decide which one is right for you.
EPA and DHA are the two omega-3s that matter here. Compare products on milligrams of EPA and DHA per serving, not on total oil weight or capsule count.
Check the serving size. Spectrum Essentials' 165 mg EPA / 330 mg DHA figure is for a two-softgel serving; Ovega-3's 135 mg EPA / 270 mg DHA is for a single-softgel serving of its 500 mg product.
Some algal formulas are DHA-only. Nested Naturals Vegan Omega-3 declares algal DHA (and, in the newer formula, Ahiflower seed oil) with no EPA listed.
In Canada, supplements are regulated as natural health products. A legally sold bottle carries an eight-digit NPN on the label; many US-market algal oils sold through online marketplaces do not.
Algal oil is grown in controlled culture rather than caught, so it does not carry the ocean food-chain contaminant profile associated with fish-derived oils.
Softgel shells differ. Spectrum Essentials uses a carrageenan-based shell, which matters if you avoid carrageenan.
Frequently Asked Questions
Which algal oil supplement has the most EPA and DHA per serving?
Spectrum Essentials Vegan Ultra Omega-3 declares the most DHA: 330 mg DHA plus 165 mg EPA per two-softgel serving, along with 25 mcg of vegan vitamin D2. Ovega-3 declares 500 mg of total omega-3s per serving, split 135 mg EPA and 270 mg DHA, in a single softgel. Nested Naturals Vegan Omega-3 is a DHA-only algal formula and declares no EPA.
Do algal oil supplements sold in Canada need an NPN?
Yes. Health Canada regulates omega-3 supplements as natural health products, and a product licensed for sale in Canada carries an eight-digit Natural Product Number (NPN) on the label. Several algal oil brands listed here are formulated for the US market and reach Canadian buyers through online marketplace sellers, so check the bottle for an NPN before you buy.
Is algal oil as good as fish oil?
It delivers the same molecules. EPA and DHA in fish oil originate in marine microalgae and accumulate up the food chain, so algal oil supplies them directly. Compare on milligrams of EPA and DHA per serving rather than on the source: an algal oil declaring 135 mg EPA and 270 mg DHA gives you the same omega-3s as a fish oil declaring the same figures. Algal oil is also grown in controlled culture rather than caught, and it has no fishy aftertaste because it is not fish-derived.
Is iWi Algae Based Omega-3 gluten-free and non-GMO?
Yes. iWi's algal oil, marketed as AlmegaPL, is Non-GMO Project Verified and gluten free. iWi sells the oil in several strengths, so check the EPA and DHA figures and the serving size on the specific bottle you order rather than assuming one number across the range.
Conclusion
The five algal oil supplements here cover the useful range: Ovega-3 for the cleanest EPA-plus-DHA split at 135 mg and 270 mg per serving, Spectrum Essentials for the highest DHA per serving at 330 mg with vegan vitamin D2 included, iWi for its AlmegaPL algal oil and Non-GMO Project Verified sourcing, and Nested Naturals for a DHA-focused plant formula. Whichever you pick, read the serving size on the bottle you receive and confirm the NPN if you are buying for use in Canada. If none of these fit, use the search tools to narrow by dose or format.
