Fish oil is the standard source of the omega-3s EPA and DHA, with evidence for cardiovascular benefit more nuanced than commonly presented — worth knowing before choosing between fish oil, algae-based, or cod liver oil sources specifically. For the full evidence picture, see our complete guide to Omega-3. Below you’ll find our picks, chosen for sustainable sourcing and third-party purity testing.

Choosing a Fish Oil Supplement
Standard fish oil (from fatty fish tissue) typically offers a higher EPA and DHA concentration per capsule than cod liver oil, which also contains vitamins A and D — worth knowing since cod liver oil needs its own vitamin A dosing considerations, covered in our cod liver oil vs fish oil guide. Look for MSC or Friend of the Sea certification for sustainable sourcing, third-party testing for contaminants like heavy metals, and enteric coating to reduce fishy aftertaste. Algae-based options provide the same EPA and DHA without fish, suitable for vegetarians and vegans. Fish oil has mild blood-thinning properties, worth discussing with your GP if you take anticoagulant medication.
