The Best Vegan Omega-3 Supplement (Fish Oil Alternative)

the best vegan omega-3 supplements

Is there such a thing as a vegan substitute for fish oil?

The answer is yes there is, and as it turns out it's also a far better alternative than any omega-3 from fish and krill oil:

An algae-based omega-3 supplement.

Now if you're unfamiliar with these algal oil supplements it's can be quite difficult knowing what to look for.

What's the difference from fish oil? Are certain brands better than others? How do you know if a product only contains vegan ingredients?

Finding the best vegan omega-3 supplement for your lifestyle doesn’t have to be such a pain in the backside. Thus I created this buying guide so you how to what ingredients to look for, and which to avoid, with some product recommendations as well.

Benefits of omega-3 (EPA & DHA) supplements

Supplementing omega-3 is certainly no health fad or trendy superfood.

As a matter of fact, during the late 700s to 1100s the Vikings consumed plenty of omega-3 in the form of fish oil, which they found helped healing, strength, energy and stamina.

Now as we'll discover there is no reason to go full Viking as there's been a recent development of new plant-based sources of omega-3.

And instead of trusting Viking anecdotes, the health benefits of the long-chain omega-3's EPA & DHA are well-documented and have been shown to:

  • Protect against heart disease
  • Enhance brain health, cognitive function and boost neural efficiency
  • Supplementing EPA & DHA during pregnancy has been associated with multiple benefits for the infant
  • Restore omega-3/omega-6 balance and reduce inflammation
  • Promote overall health and well-being 
  • Treat depression
  • Ease pain of rheumatoid arthritis

"I just feel fantastic and my skin is so vibrant from this cod liver oil, you should try it bro" @ Viking year 787

While the omega-3 fatty acid ALA (found in seeds such as chia and flax) can be converted to EPA & DHA in the body, this conversion rate is rather poor. 

And as we as plant-eaters don't have any preformed EPA & DHA in our diet, in the form of seafood and fatty fish, consequently our levels of these long-chain omega-3s are also low.

To reap all the health benefits listed above a vegan omega-3 supplement is the best alternative.

"But this is preposterous, you're making all these claims with no cited studies!!!!"

The scope of this article is to provide the information needed to find a good vegan omega-3 supplement. For cited sources and in-depth information check out this article which goes through all the nitty gritty of vegan omega-3. 

Why fish oil is a bad idea 

fish in water

Cause you wanna leave this fellow in the sea.

The traditional form of omega-3 supplements is fish and krill oil capsules, which basically is the oil extracted from fatty fish through different processes.

Obviously this is not a viable option on a vegan diet...

...we want to leave the fish left alone in the sea with their scaly fish friends.

However even if you allow animal products in your diet fish oil is a pretty shitty option - for several reasons. 

Many fish oil supplements on the market are oxidized, or using the colloquial term, rancid.

No wonder seeing as the fish first has to be caught, transported to shore where it's then fractionated into fish oil, then stored in large tanks and shipped away to a factory for further refining, this refining process involves several steps including repeated heating at high temperatures and deodorisation to remove undesirable taste and rancidity.


So as a consumer you've basically no idea where the fish oil came from, how old it is and how many steps of refinement and heating it has undergone. 

Now there's one more problem:


Fat-soluble pollutants, such as polychlorinated biphenyls, may biomagnify in marine food chains and may end up in concentrated amounts in your fish oil supplements. 

One study done on rats found that fish oil (contaminated with aspolychlorinated biphenyls and organochlorine pesticides) showed significant negative effects on oxidative stress and antioxidant capacity in rats.

An algae-based omega-3

A much better plant-based alternative is algal oil, or marine algae, which provides heaps of both EPA & DHA.

Now you might be wondering:

Wait what - why would algae contain EPA & DHA, isn't that a strictly fish thing?

Fish actually get their DHA and EPA by eating micro algae floating around in the ocean.

So fish is kind of like an omega-3 middleman. Why not go directly for the plant source instead?

That way we don't have to ingest contaminants like heavy metals, bioaccumulated toxins and pollutants, and it's also more environmentally friendly and sustainable. 

What to look for in vegan omega-3 supplements

The first thing to do when examining your omega-3 supplement is to scan the nutrition label for the quantities EPA & DHA.  

For instance the label might say each pill contains 1100 mg of omega-3.

But if you take a closer look there's only 200 mg of EPA & DHA. The rest 900 mg of omega-3 might be in the form of ALA or some other fat.

Basically you want your product to contain this. 

Ideally you want a product with plenty of both EPA & DHA - so you ensure you get enough of these important nutrients with each serving. And ultimately save some money by not buying a supplement with lots of filler ingredients.

Secondly, make sure to take a good look at the source of the omega-3:

We certainly don't want to accidently take rancid fish oil. The product should clearly state that the omega-3 is derived from algae and nothing else.

To ensure quality and purity the supplement should also be produced to GMP certified standards and tested by an independent or third-party testing group.

And if you want to avoid the distinct "seaweedy/fishy" omega-3 burps, look for ingredients such as lemon or peppermint to mask this odor.

What to avoid

As noted above definitely make sure your omega-3 is not derived from fish oil.

Furthermore you'd be suprised by the many ways that animal products sneak their way into many innocent supplements.

Be on the lookout for gelatin - used as a gelling agent, thickener, and stabilizer to make the soft shell of capsules. Gelatin is super-not-vegan as it's made from boiling a bunch of different animal products. 

Instead of gelatin many vegan omega-3 supplements use carrageenan instead, a gelling agent derived from red seaweed. 

While it sounds rather harmless there's some controversy surrounding this food addtive:

Some evidence suggests that carrageenan initiates inflammation in human colonic epithelial cells and that degraded carrageenan, known as poligeenan, has cancer-promoting effects.

Now it's very important to make the distinction between carrageenan and degraded carrageenan, the latter exhibiting toxic effects that carrageenan doesn't.

A review from 2014 deemed carrageenan to be safe as it isn't degraded by the GI tract and basically flows through our system as any fiber would. 

There's still some questions marks as the National Organic Standards Board (NOSB) recently recommended that carrageenan should be removed as an allowed ingredient in organic foods The USDA will make a final decision in 2018.

Recommendations for vegan omega-3 supplements

There are plenty of options for vegans that want to ensure an adequate intake of EPA and DHA, without wrecking the fish population and ingesting toxins and pollutants.

To make this easier for you I've listed the best cruelty-free omega-3 supplements.

It would get very repetitive, very fast if I mentioned the health benefits of EPA & DHA with every product - hence I'll focus the reviews moreso on the quality of the supplement rather than the health aspects. 

Bloom Algae-Based Vegan Omega 3 DHA & EPA

Bloom Algae-Based Omega-3 is a great vegan supplement that definitely packs an omega-3 punch.

Each serving provides plenty of these crucial nutrients: 336 mg DHA, 158 EPA, and lo and behold, 36 mg of DPA.

So what stands out immediately is the large amounts of omega-3's - which is great.

Noteworthy is also the inclusion of docosapentaenoic acid (DPA) - an elongated form of EPA. While the focus often revolves around the health benefits of EPA & DHA, research suggests that DPA can help prevent blood clots and wound healing as well as reduce inflammation.

Bloom omega-3 is made from farm-raised non-GMO algae and processed in a GMP certified facility which ensures quality and purity. You can rest assured that this supplement is free of any ocean-borne toxins, pollutants and contaminants.

As it's derived from farm-raised algae and includes natural lemon and peppermint flavouring these won’t give you the dreaded “seaweed/fish burps".

The ingredient list is also super clean and is one of few algae-based supplements that doesn't contain carrageenan. Vitamin E is added for its antioxidative powers to prevent any fatty acids from oxidizing.

Users report good experiences with no "fish-burps" or any other issues with digestion. 

  • 100% vegan
  • Each serving contains a large dosage of omega-3s: 336 mg DHA and 158 mg EPA.
  • ...Along with 36 mg of DPA
  • Derived from farm-raised non-GMO algae and manufactured in a GMP certified facility
  • Free of toxins, pollutants and contaminants such as dioxins, mercury and PCBs
  • Free of carrageenan
  • Addition of lemon and peppermint won’t give you “fishy burps"
  • Small, easy to swallow soft gels
  • A serving constitutes 2 pills so it won't last you super long (though it does provide more EPA & DHA than other supplements)
Nested Naturals Vegan Omega-3

Nested Naturals Vegan Omega-3 will take care of your EPA & DHA needs with ease.

Each serving contains 200 mg DHA, 100 mg EPA, and 67 mg of unspecified forms of omega-3. 

What I like about this particular product is the minimalistic approach to the ingredients used. If you look at the nutrition label it's quite uncluttered, there's nothing there that doesn't have to be there (and also free from carrageenan)

I also like that they've opted to use a natural anti-oxidant to preserve the omega-3 fatty acids: each serving contains 100 mg of green tea extract.

The vegan algal oil is derived from marine algae grown sustainably on a farm, not harvested from the ocean, which means you get pure and high-quality supplement. Third party testing further ensures there's no contamination or other toxins present. 

Now on the flipside the simple ingredient list means there are nothing to mask the fishy/seaweedy/oceany flavor - which might give it a not so pleasant smell. (however if you prefer a no frills, basic omega-3 supplement this will be your best bet)

The pills are quite large, 2.5 cm long and 0.7 cm, wide which is a downside for those that struggle with swallowing large pills.

  • 100% vegan
  • Each serving contains 200 mg DHA and 100 mg EPA.
  • To prevent oxidation contains natural antioxidant green tea extract
  • Made from sustainably farm-raised marine algae 
  • Free of toxins, pollutants and contaminants such as dioxins, mercury and PCBs
  • Very clean ingredient list and no added artificial fillers, flavourings or preservatives.
  • Pills are quite large and might be hard to swallow.
  • ban
    Nothing to mask the "fish/seaweed" smell
Ovega-3 Vegetarian/Vegan Omega-3

Ovega-3 Vegetarian/Vegan Omega-3 is a popular cruelty-free supplement to get your precious plant-based EPA & DHA. 

What I like about this product is that each serving contains a heaping 270 mg DHA and 135 mg EPA - which is a very good dosage for the long-chain omega-3s. 

This supplement delivers high quality, sustainable omega-3s without a fishy aftertaste or risk of ocean-borne pollutants and toxins. It also contains rosemary extract and antioxidants such as vitamin E and C to prevent oxidation.

However what makes this product less attractive is that it contains seemingly unnecesary ingredients such as corn starch (?), beta carotene, sorbitol and caramel color. It also contains the somewhat controversial carrageenan if that bothers you. 

Users report that the pills are quite large but still easy to swallow with no mention of the "fishy-burps" some products result in. 

  • 100% vegan
  • Good budget-friendly alternative as you get a heaping dosage of omega-3s in each serving
  • Each serving contains 270 mg DHA and 135 mg EPA.
  • Made from sustainably farm-raised marine algae 
  • Free of toxins, pollutants and contaminants such as dioxins, mercury and PCBs
  • Contains controversial carrageenan
  • ban
    Contains unnecessary stuff like corn starch and caramel color  
Amala Vegan Omega-3 Supplement

Amala Vegan Omega-3 Supplement provides the important long-chain omega-3's that also suits the vegan lifestyle. 

Each serving contains 120 mg DHA, 72 mg EPA and 13 mg DPA. 

As this supplement is made from an eco-friendly and sustainable algae-farm, it results in a product free of toxins such as mercury, PCB's, and dioxin. 

To avoid the fishy aftertaste and "sea-weed" burps it features a delayed release formula and natural lemon and peppermint flavors. It also contains rosemary extract and antioxidants such as vitamin E and C to keep the fatty acids free from oxidation.

This product is free from the controversial carrageenan and presents a relatively clean nutrition label.  

Users report overall good experiences and that the peppermint flavor effectively conceals any fishy burps.

One negative is that each serving doesn't provide plenty of omega-3's - about half compared to other brands. However you do get 90 pills in a container so you could just up the dosage to 2 pills.

  • 100% vegan
  • Each serving contains 120 mg DHA, 72 mg EPA and 13 mg DPA.
  • Made from marine algae  grown in sustainable eco-friendly farms
  • Free of toxins, pollutants and contaminants such as dioxins, mercury and PCBs
  • Rosemary extract and vitamin E and C prevents fatty acids from oxidizing
  • Free from carrageenan
  • Contains small amounts of omega-3 per serving

In conclusion: the top pick

Out of the products listed the Bloom Algae-Based Vegan Omega 3 DHA & EPA would me typ top recommendation.

It provides good value and a heaping dosage of the long-chain omega-3s (including DPA) per serving, it's made from farm-raised non-GMO algae with a very clean ingredient list free from carrageenan, and includes natural lemon and peppermint so you'll avoid "sea-weed" burps. 

Well - that's it for vegan omega-3 supplements. I hope you learned a thing or two.
