What it is

Oil pressed from Euphausia superba krill.

Why not vegan

Krill are animals foundational to the Southern Ocean food web.

What a “Not vegan” verdict means

A not-vegan verdict means the ingredient is animal-derived in essentially all commercial supply, so a product listing it should be treated as non-vegan unless the manufacturer explicitly states a plant-based source in writing.

Where you'll find it

  • Omega-3 supplements
  • Some fortified foods

How to read the label

Krill Oil belongs to the vitamins and supplements family. These are the terms worth scanning for on any ingredient list in this category:

  • Cholecalciferol
  • Vitamin D3
  • Lanolin
  • Gelatine capsule
  • Fish oil
  • Omega-3
  • Shellac coating
  • Stearic acid
  1. Prefer D2 (ergocalciferol) or D3 explicitly labelled 'from lichen'.
  2. Look for 'vegetarian capsule', 'HPMC' or 'pullulan' on the shell.
  3. Choose algal oil for EPA and DHA rather than fish or krill.
  4. Check tablet coatings — shellac and carnauba are both used, only carnauba is vegan.

Mistakes to avoid

Common vitamins and supplements traps and what to do about them
Where it catches people outWhat to do
Fortified plant milkThe added D can still be lanolin D3. Brands that use lichen say so prominently.
Multivitamin gummiesGelatine base plus beeswax polish is the standard formulation.
Magnesium stearateUsually vegetable but can be tallow-derived; ask if it matters to you.

Vitamins and supplements in context

Fortification quietly reintroduces animal ingredients into otherwise plant-based food. Vitamin D3 is conventionally made from lanolin in sheep's wool, omega-3 from fish oil, and some vitamin A and E preparations use animal-derived carriers.

Plant-based routes exist for nearly all of them: lichen-derived D3, algal DHA and EPA, and synthetic or vegetable-sourced tocopherols. They cost more, so the default in cheap fortified products is the animal route.

Capsule shells matter as much as the contents — most soft-gel and many hard capsules are gelatine, while vegan supplements use HPMC (hydroxypropyl methylcellulose) or pullulan.

Does certification help? Supplements are a category where vegan certification genuinely pays: it covers both the active ingredient source and the capsule shell, which the ingredient panel often obscures.

Vegan alternatives

  • Algae oil
  • Flax/chia ALA sources

FAQ

Is krill 'sustainable'?
Industry claims are contested by marine biologists; vegans avoid regardless.
Is vitamin D3 always non-vegan?
No. Lichen-derived D3 is chemically identical and fully plant-based; it is labelled explicitly because it costs more.
Do vegans need B12 supplements?
Yes. Reliable B12 comes from fortified foods or supplements, and cyanocobalamin is produced by bacterial fermentation, so it is vegan.
