Omega-3 supplement types compared

Factual, non-medical comparison of common omega-3 supplement sources. The effective dose is EPA + DHA content, and prices below are ranked by EUR per 1g EPA+DHA regardless of source. Different sources carry different fatty acid profiles and phospholipid vs triglyceride forms.

What you should know about omega-3 sources

Omega-3 supplements come from different biological sources. The key active compounds are EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). The ranking standardizes on these regardless of source:

Source Typical EPA+DHA per serving Form Notes
Fish oil 300–1000mg Triglyceride / ethyl ester Most common and studied. Concentrate options push higher EPA+DHA per softgel, often the best value per effective dose.
Krill oil 100–250mg Phospholipid Lower EPA+DHA per softgel, typically more expensive per effective gram. Phospholipid form is different from fish oil triglycerides.
Algal oil 200–450mg Triglyceride Plant-based, vegan DHA+EPA source. Often higher DHA:EPA ratio. Grown from microalgae.
Cod liver oil 80–200mg Triglyceride Traditional source. Also provides vitamins A and D. Lower EPA+DHA concentration per gram.

DosePrice does not provide medical advice. The rankings reflect price per effective gram of EPA+DHA only. Triglyceride and ethyl ester forms are treated as equivalent in the normalization. Which source is right for you depends on your individual needs.
