4 Best Vegan Omega-3 Supplements of 2025 [Full Comparison]

If you’re someone who cares about quality, purity, and effective dosing in a plant-based omega-3 supplement, Momentous Vegan Omega-3 stands out for a few key reasons.

Unlike most plant-based options that rely on seed oils rich in ALA, his supplement uses algae oil, delivering these essential fatty acids in a highly bioavailable form so your omega-3 intake doesn’t suffer. That means you’re getting the same brain, heart, and cellular benefits you would from traditional fish oil, but without any animal ingredients.

What’s particularly unique about Momentous is its 1:1 EPA to DHA ratio, which is almost unheard of in vegan supplements. This balance mirrors the ratios often found in high-quality fish oil, making it an excellent choice for those wanting to support cognitive function, muscle recovery, and overall cellular health with precision.

Another major plus is its NSF Certified for Sport status, giving you peace of mind that this supplement has been thoroughly tested for purity and is free from contaminants—a reassurance not all brands can provide.

Momentous takes product standards and quality seriously. The Momentous Standard guides all that we do, with rigorous testing, science in action, and only the essential, highest-quality ingredients in every product. Our new Vegan Omega-3 is the full expression of the Momentous Standard in action.

With our standards for sourcing and testing, this isn’t the cheapest vegan omega-3 on the market. If price is your most important factor, there are lower-cost options available. However, for those who prioritize clean ingredients, quality, and science-backed formulations, it’s hard to overlook what this product offers.

If you want vegan omega-3s you can trust to deliver real results, this is absolutely worth trying for yourself.

Nordic Naturals Algae Omega is a solid, well-rounded choice for anyone looking for a vegan-friendly omega-3 supplement at a reasonable price point. It delivers 715 mg of total omega-3s per serving, with a higher emphasis on DHA (390 mg) compared to EPA (195 mg). While the EPA content is a little lower than some might prefer for specific health goals, this formula still provides meaningful support for brain health, heart function, and overall wellness.

One of the key benefits of this supplement is its algae-based source, which means you’re getting preformed EPA and DHA—not the less-effective ALA found in seed oils. It’s also third-party tested for purity, non-GMO verified, and certified vegan, giving you added peace of mind about what you’re putting into your body.

At just over $30 for 60 servings, it’s a cost-effective option with the convenience of a 10% subscription discount and free shipping. However, it’s worth noting this product doesn’t carry the NSF Certified for Sport certification as the Momentous product does, so if you’re an athlete subject to rigorous testing or want that added peace of mind about banned substances, you might prefer a brand with that extra assurance.

Overall, this is a reliable, clean, and affordable choice for daily vegan omega-3 supplementation.

Garden of Life’s Minami Algae Omega-3 Vegan DHA is a strong choice for anyone seeking a high-quality, plant-based DHA supplement. With 500 mg of DHA per serving and no EPA, it’s particularly well-suited to those focused on cognitive health and cellular function rather than broader inflammation support. If you’re looking for that EPA content then this isn’t the product for you.

One of its standout benefits is the use of Minami’s highly concentrated algae oil, meaning you get more omega-3 per capsule and fewer pills to swallow. The formula is clean—gluten-free, GMO-free, and vegan—and customers consistently praise it for having no fishy aftertaste. It is orange-flavored with a light citrus taste.

While Minami conducts its own rigorous in-house testing for purity and safety, it’s worth noting this product lacks third-party certifications like NSF Certified for Sport, which may matter to some consumers.

If your primary focus is boosting DHA intake through a well-respected, highly concentrated algae oil, this is a convenient and effective option worth considering.

Sports Research Vegan Omega-3 is a strong contender for those seeking a well-rounded, high-potency vegan omega-3 supplement. Each serving delivers an impressive 1250 mg dose of total omega-3s, including 280 mg of EPA and 700 mg of DHA—making it one of the more robust options for vegetarians or vegans wanting both cognitive and cardiovascular support.

This algae-based formula ensures superior bioavailability and avoids the common pitfalls of seed oil-based supplements. Sports Research has also prioritized capsule innovation with their Plantgel™ technology, which is carrageenan-free and Non-GMO Project Verified.

The supplement is manufactured in cGMP-compliant facilities and third-party tested for quality, providing extra confidence in its purity and sourcing. While it lacks NSF Certified for Sport certification, it’s still a solid choice for most consumers.

If you’re looking for a clean, high-quality vegan omega-3 supplement with a good EPA/DHA balance and a focus on sustainability, this product delivers.
