Omega-3: ALA, EPA, DHA, and labels
By the VitaCoreGuide Editorial Team · Last reviewed September 8, 2026
Omega-3s are polyunsaturated fats. ALA is common in plant foods, while EPA and DHA are found mainly in seafood and certain supplements.
Food sources
Fatty fish such as salmon, sardines, herring, and mackerel provide EPA and DHA. Flax, chia, walnuts, and certain oils provide ALA.
Fish oil and algae oil
Fish oil is a common EPA and DHA source. Algae-based products may be suitable for shoppers seeking non-fish options; their EPA and DHA content varies by product.
How to compare labels
Check EPA and DHA amounts per serving rather than relying only on total oil weight. Review serving size, source, storage directions, allergens, and other ingredients. Ask a professional about pregnancy, medications, conditions, allergies, or high doses.
