What is Omega-3?
Omega-3 fatty acids (EPA and DHA) are essential long-chain polyunsaturated fats found in fish oil, krill oil, and algae. They are the most studied supplement for cardiovascular health, with multiple large randomized controlled trials showing reductions in triglycerides, blood pressure, and cardiovascular events. EPA and DHA are also key structural components of brain tissue and resolve inflammation through specialized pro-resolving mediators (SPMs). Most adults do not consume enough EPA/DHA from diet alone.
Evidence grade: A. The single best-supported longevity supplement most people don't take enough of. Read the full evidence review: Omega-3 ingredient page.
How we rank Omega-3 supplements
Every Omega-3 product in our database is scored on five pillars:
- Dose honesty: Does the product contain the amount stated on the label? We check against published third-party assay results when available.
- Evidence: Omega-3 has evidence grade A. Products that cite relevant trials score higher.
- Price per month: Total monthly cost based on label serving recommendations.
- Third-party testing: Does the brand publish a Certificate of Analysis (CoA) from an independent lab?
- Transparency: Is the full formula public? Are all ingredient amounts disclosed?
See the full methodology for the scoring formula.
What to look for in a Omega-3 supplement
- Dose: Look for at least 1,000 mg combined EPA+DHA per serving. Cardiovascular trials typically use 1,000 to 4,000 mg per day.
- Form: Triglyceride form has better absorption than ethyl ester. Krill oil provides phospholipid-bound omega-3. Algae oil is the only vegan source of direct EPA/DHA.
- Purity: Check for third-party testing showing low oxidation (TOTOX value below 26) and no heavy metals (lead, mercury, arsenic below safe limits).
- Price: Omega-3 prices range from $8 to $40+ per month. Compare cost per 1,000 mg EPA+DHA, not cost per capsule.
- Testing: Third-party testing is essential for fish oil. Look for IFOS, Friend of the Sea, or equivalent certification.
