Vegan omega-3 supplements scattered across a marble worktop

Best vegan omega-3 supplements to buy UK (2023)

Nothing fishy here, just some really effective vegan omega-3 supplements which have come straight from the source - algae. Take a look through my top picks.


Most people know just how important omega-3 is, but not many know where it actually comes from. There is a heavy reliance upon fish oils and capsules, probably because that is what is so readily available. It is what I took before I went vegan.

I believe that because of this reliance upon fish oil, many people think that this is the best source of omega-3. On top of this, you may even get those pesky non-vegans ‘fish’mongering, with their “you can’t get high-quality sources of omega-3 that absorb without eating salmon” rubbish.

So, it is no surprise that when you turn vegan, it is hard to find out where you can get good plant-based sources of this important fatty acid.

And when I say important, I mean vital. We MUST get it in our diets as our bodies cannot produce it themselves. So, if you would like to get into the nitty-gritty of omega-3 before we get into the best vegan omega-3 supplements that you can buy, then head to the bottom of this article to read the more detailed FAQs.

I am here to show you that there are plenty of nutritious vegan sources of omega-3 and you can get your daily intake from all of these awesome vegan omega-3 supplements below.

Here are the most effective vegan omega-3 supplements

Whilst I’d say we could all just start eating a lot more seaweed, it is difficult to know how much you’d be consuming and you may get a little sick of the taste. So, I would recommend checking out a vegan omega-3 supplement brand to ensure you get the required daily dose to keep your brain healthy!

I myself take a vegan omega-3 supplement every day. I have been trying out many different brands and will now present to you my top picks.

Best high-strength option

Ethical Nutrition

Nutrition: 140mg EPA & 420mg DHA per serving
Form: Softgel capsule
Serving: 2 capsules a day
Packaging: Completely plastic-free in a recyclable glass jar & aluminium lid

Ethical Nutrition is a family-run business with a fully vegan range of vitamins and supplements, including these high-strength vegan omega-3 softgel supplements.

They are very transparent about the way they run their business, stating they have no outside investors or pharmaceutical ownership, which I love. With so many supplement companies popping up, it is hard to know which to put your trust in!

Not only is their business run ethically, but their vegan omega-3 supplement is also really ethical. They use natural sources of algae grown in controlled environments, so no nasty toxins will make their way into these!

It is the highest DHA I’ve seen per serving, which is awesome. And they also assure me that it is high absorbable as it is in triglyceride form. They have a really neutral taste, so nothing fishy here!

I have been taking these for a few months now and my hair is noticeably shinier, my skin is experiencing less eczema breakouts and my mind feels less foggy!

Ethical Nutrition is also really conscious about its packaging, which is completely plastic-free (and no bio-plastics either!). The omega-3 comes packaged inside a glass jar. You can easily reuse these to make homemade jams, store things, or simply recycle.

Best science-backed brand


Nutrition: 150mg EPA & 300mg DHA per serving
Form: Softgel capsule
Serving: 2 capsules a day
Packaging: Compostable packaging (but not home compostable) with a reusable aluminium tin

DR.VEGAN are a fully vegan company and not only do they show this in their brand name, they also provide a lot of helpful content for plant-based diets on their website.

You can find out more about the brand itself in my DR.VEGAN review.

Because they are a vegan company, you can feel safe in the knowledge that all the products they sell are made with plant-based ingredients. So, the same goes for their omega-3 supplement.

They use high-strength and highly absorbable sources of omega-3 that are grown in controlled environments, so you can be sure they are full of what they say they are.

Each serving is made up of 150mg EPA and 300mg DHA, which is above the recommended daily amount.

Whilst they do state that their packaging is compostable, it does still contain bioplastics which are definitely a lot better than traditional plastic, but they do need to be composted at controlled higher temperatures in order to truly decompose. So you won’t be able to do this in your garden.

Best slimline capsule


Nutrition: 150mg EPA & 300mg DHA per serving
Form: Capsule
Serving: 2 capsules a day
Packaging: Compostable packaging (but not home compostable)

Feel is a fully vegan supplement company specialising in vitamins and shakes, as well as these vegan omega-3 capsules.

They are quite affordable if you subscribe on a monthly basis. I have tried their subscription service myself and found it really easy to pause and cancel when needed. Their one-off purchase is also very affordable in comparison to other brands.

Their EPA and DHA levels are similar to other brands and they also come from algae grown in controlled environments. The main difference here is their choice of the capsule. Many of the other brands use a soft gel capsule, but Feel uses a standard pill capsule that is a lot more slimline which is good for anyone who struggles to swallow larger rounder pills.

Because of the capsule, I do sometimes find you can taste the algae. It isn’t too fishy but it can be offputting for some people.

Like DR.VEGAN, their packaging is compostable, but not home compostable.

Best affordable option


Nutrition: 125mg EPA & 250mg DHA per serving
Form: Softgel capsule
Serving: 1 capsule a day
Packaging: Recyclable plastic packaging

If you are looking for an affordable vegan omega-3 supplement then you’ll really like these by MYVEGAN, the huge vegan supplement company known for affordable vegan protein powders and snacks.

They are the only option that I have mentioned here that comes packaged inside plastic, but this is probably what makes these much more affordable than the rest. I do like that you can buy a 6-month supply that comes inside one plastic tub, which is amazing.

As long as you recycle the plastic tub there are arguments to suggest that this is less taxing on the environment at the moment than buying bioplastic packaging that doesn’t get disposed of correctly.

You only need to take one capsule a day which is great, but they are a bit larger than the rest. So they aren’t great for anyone who struggles to swallow pills. But there is no fishy aftertaste with these.

Ultimately, I recommend these for anyone who likes to bulk buy or wants to look after their health but doesn’t have the money to buy all the high-end supplements.

Best eco-friendly packaging


Nutrition: 124mg EPA & 198mg DHA per serving
Form: Softgel capsule
Serving: 1 capsule a day
Packaging: Aluminium tin

Vitl is a personalised nutrition brand specialising in home nutrition tests and tailor-made vitamins. They also have a range of omega-3 supplements (mostly fish-based) which includes a vegan omega-3 option.

Their vegan omega-3 softgels are relatively high per capsule, meaning you only need to take one capsule every day. But you can also take two a day if you want to go with a higher dose and because it is quite affordable you can easily do this!

I find them really easy to swallow and there is absolutely no fishy aftertaste. Personally, I love the aluminium tin which is infinitely recyclable and keeps all of the softgels nice and compact.

Since they do use animal products in some of their other supplements this may not be a suitable brand for anyone who prefers to buy from 100% vegan companies.

Best in-store option

Together Health

Nutrition: 123mg EPA & 207mg DHA per serving
Form: Softgel capsule
Serving: 1 capsule a day
Packaging: Compostable packaging (but not home compostable)

Together Health is a fully vegan-certified supplement brand. This includes their omega-3 supplements which come packaged in compostable packaging. Although I’m pretty certain this like many others contain bioplastics, so it isn’t home-compostable.

They have a really random nutrition make-up of EPA and DHA, but they claim it is the perfect ratio for your brain health. They also have a very neutral taste and can be easily swallowed.

This is one of the easiest brands to find in stores and online supermarkets, as they are sold in Holland & Barrett, Ocado, and Morrisons. Meaning it is a really great option for anyone who prefers to do in-store shopping or anyone who likes to get all their supplements on their online grocery shops.

They are very affordable, being one of the cheapest here that you can buy as a one-off purchase.

Best for kids & teenagers


Nutrition: 80mg DHA per serving
Form: Gummy
Serving: 1 gummy a day
Packaging: Compostable packaging

Vegums are a fully vegan-certified company specialising in vegan vitamins in gummy form. These vegan omega-3 gummies are orange-flavoured and low in sugar, but still sweet. They also contain some Vitamin E for an extra immunity boost.

This makes them perfect for both adults and kids. You’ll never forget to take your vitamins again if they taste like these!

They do however have the lowest potency of omega-3. Apparently, this is down to the fact that they are in gummy form, so any higher and they wouldn’t have the right consistency to create a chewy sweet.

They also don’t contain any EPA, but they say that this is because we should get enough of this from converted ALA in our diets.

If you do eat a lot of ALA rich foods then you could probably just take these supplements, or maybe get these for your kids!

Vegan omega-3 FAQs

Nutrition can be incredibly confusing, especially when following a vegan diet. This isn’t because there aren’t vegan sources of the important nutrients, it is more to do with there being less information out there for vegans. Thankfully, it is now getting a lot easier! More people are vegan now than ever and there is a lot more research being put into it.

Therefore, we now know a lot more about vegan omega-3. I myself have done a lot of research into it when first finding a suitable vegan omega-3 supplement to take and when planning for this blog piece.

Hopefully I can share with you what I have learnt about following a vegan diet and getting enough omega-3!

Omega-3 refers to a family of three fatty acids, ALA, DHA, and EPA.

ALA is used for energy and is found in many plant-based sources including flaxseeds, walnuts and chia seeds. DHA and EPA, the most important omega-3 acids, are pretty vital in the maintenance of healthy brains. Whilst a small percentage of ALA can be converted into DHA and EPA, they are mostly sourced from animal-based foods, particularly fish.

Some signs of an omega-3 deficiency include: dry and scaly skin, fatigue, poor memory and concentration, depression, and joint pain. However, it is recommended to see a doctor for a proper diagnosis, as these symptoms can be caused by other factors as well. Blood tests can also be done to measure the levels of omega-3 fatty acids in the body.

ALA can be found in many plant-based food sources including rapeseed oil, flaxseeds, walnuts and chia seeds.

Sources of DHA and EPA are traditionally seen as coming from fish. So people are recommend to take fish oil supplements or consume lots of salmon.

But where do these fish get their omega-3 from? Well, from algae of course.

The fish themselves aren’t actually an original source. The algae that they eat are. And we too can go direct to the source and leave out the cruelty.

I feel like this is the B12 situation all over again. Animals aren’t sources of B12, but the food and supplements they consume are. But the vegan community had to put up with a lot of ridicule about meat being the only source of B12 for quite some time!

The same goes for omega-3. But now there is plenty of information out there and tonnes of amazing brands utilising algae to create vegan-friendly supplements. Which brings me on to the reason we are all here – the best most effective vegan omega-3 supplements you can buy!

Vegan omega-3 supplements go straight to the source of omega-3, algae. They grow this and extract the fatty acids in controlled environments so that they can deliver high potent pure sources of omega-3. So yes, vegan omega-3 supplements which use algae are very effective.

They are also much more pure than fish-based omega-3 supplements. This is because fish oils contain toxins and other nasties that they may have ingested from our polluted seas.

Vegan omega-3 supplements can be made from a variety of sources, including flaxseed oil and walnuts. But the most effective vegan omega-3 supplements which provide high levels of DHA and EPA, are made from algae.

The algae is grown in controlled environments and then harvested, ensuring it is a pure source of vegan omega-3.
