Is omega-3 vegan?
Quick answer: It depends on the source. Omega-3 added to foods or sold as supplements may come from fish oil (not vegan) or from algae, flax or rapeseed (vegan).
Also called: omega-3, EPA, DHA, fish oil, algal oil, algae oil, ALA
The details
Plant foods supply ALA, while the long-chain omega-3s EPA and DHA in supplements and fortified foods usually come from fish oil or from microalgae. The NIH notes that plant-based omega-3s from algal oil usually provide around 100–300 mg DHA, sometimes with EPA.
Omega-3 enriched bread, spreads, juices, yoghurts and eggs often use fish oil. Look for “algal oil”, “from algae” or a vegan logo; many fish-oil and some algae capsules are made of gelatin.
