Not all fish oil is created equal. A 1,000mg fish oil softgel might contain only 300mg of the EPA and DHA you actually need — meaning you would need 3–4 capsules to hit a useful dose. We compared omega-3 supplements by their actual EPA/DHA content per dollar, not total fish oil weight.
TL;DR — Quick Summary
- ✓What matters: EPA + DHA content per serving, not total fish oil milligrams
- ✓Target dose: 1–2g combined EPA/DHA daily for general health, 2–3g for anti-inflammatory benefits
- ✓Best overall: Nordic Naturals Ultimate Omega — 1,280mg EPA/DHA, triglyceride form, IFOS 5-star
- ✓Best value: Nature Made Fish Oil 1200mg — Costco staple, USP verified, affordable
- ✓Best premium: Thorne Super EPA — 1,100mg EPA/DHA, NSF Certified for Sport
- ✓Triglyceride (TG) form absorbs better than ethyl ester (EE) — check the label
- ✓Vegetarian option: algae-based DHA (Nordic Naturals Algae Omega or Thorne Omega-3 w/ CoQ10)
EPA vs DHA — What Is the Difference?
EPA (eicosapentaenoic acid) is primarily anti-inflammatory — it reduces joint pain, supports cardiovascular health, and may improve mood. DHA (docosahexaenoic acid) is critical for brain health, cognitive function, and eye health. Most people benefit from a balanced EPA/DHA ratio, but those focused on joint pain or inflammation may want a higher-EPA formula.

Store fish oil in the refrigerator after opening to slow oxidation and reduce fishy burps. If your fish oil smells strongly of fish, it may be oxidized — fresh fish oil should have a mild, ocean-like scent.
