More about omega-3 (fish or algae)
Omega-3 fatty acids are fats the body needs. The main long-chain forms are EPA and DHA, found in oily fish, fish oil, krill oil and algae oil. The plant form, ALA, is found in flaxseed, chia and walnuts.
Supplements are sold as fish oil, krill oil or algal oil, and the capsule shell is often gelatine, which is a separate ingredient to check.
Is omega-3 (fish or algae) vegetarian or vegan?
It depends on the source. Fish oil is not vegetarian; algae oil is vegetarian and vegan.

Fish oil and omega-3: the short answer
Fish oil is halal in every school of thought, because fish is halal and does not need slaughter. Omega-3 from algae is halal too. The part to check is the capsule: most soft capsules are made of gelatine, which in the UK is usually from cattle or pigs.
Sources of omega-3
| Source | Halal status | Note |
|---|---|---|
| Fish oil (cod liver, salmon, anchovy, sardine) | Halal | All schools permit fish |
| Krill oil | Halal for most | Krill are crustaceans; the Hanafi setting marks them doubtful. See krill oil |
| Algal oil | Halal | Plant-based; see algal oil |
| Flaxseed and other plant oils (ALA) | Halal | Plant-based |
Capsules: the real question
| Capsule | Made from | Halal status |
|---|---|---|
| Softgel with "gelatine" | Usually bovine or porcine | Doubtful or haram unless certified |
| Fish gelatine capsule | Fish | Halal |
| Halal gelatine capsule | Halal-slaughtered cattle | Halal |
| Vegetarian capsule (HPMC) | Plant cellulose | Halal |
| Liquid oil (no capsule) | Fish or algae | Halal |
Liquid fish oil, fish-gelatine softgels and algal oil in vegetarian capsules avoid the problem entirely.
Halal fish oil brands
Several supplement brands sell omega-3 in fish-gelatine or plant capsules, and some carry halal certification from recognised bodies. As with food, look for a named certifier's logo on the pack, and check that the capsule material is stated. A product that says "gelatine" without a source is best avoided.
Omega-3 in food
DHA and EPA are added to some baby formula, milks, eggs and spreads. In food they usually come from fish or algal oil and are halal. See baby formula.
