Omega-3 status turns entirely on the source. Fish oil and krill oil are animal-derived, placing them outside vegan and, as marine-animal products, outside vegetarian claims. Algal oil, grown from microalgae, and ALA from flax or chia are plant- and microbe-based and compatible with both. The finished supplement label states EPA and DHA content but not always the source, which is what a review confirms.
What it means for each mark
- VeganCompatible only when from algae or plants such as flax and chia; fish oil, krill oil and other marine sources are animal-derived.
- VegetarianFish and krill oils are marine-animal products, outside vegetarian standards; algal and flax-derived omega-3 are compatible.
Where it typically hides
- Fish, krill and algal oil supplements
- Fortified milks, juices and eggs
- Infant formula and toddler foods
- Functional foods and meal replacements
- Softgel capsules, whose shells may add a separate animal question
What a certification review asks for
- A source declaration distinguishing marine oil from algal or plant omega-3
- The capsule shell specification, since softgels are often gelatin
- Non-GMO documentation for algal oil where the strain or feedstock may be engineered
Alternatives
- Algal oil (microalgae-derived EPA and DHA)
- Flaxseed, chia and walnut oils for ALA
- Non-gelatin capsule shells (HPMC or pullulan)
Frequently asked questions
Is omega-3 vegan?
Only from the right source. Omega-3 from fish oil or krill oil is animal-derived and not vegan, while omega-3 from algal oil, flax or chia is plant- or microbe-based and compatible with vegan and vegetarian claims.
Is there a vegan source of EPA and DHA?
Yes. Algal oil, produced from microalgae, supplies EPA and DHA directly without fish. Flax and chia provide ALA, which the body converts to EPA and DHA less efficiently. A supplier declaration confirms the algal source.
