Updated: January 2025 • 7 min read
Omega-3 fatty acids are essential for heart, brain, and joint health. But with so many options - fish oil, krill oil, algae oil - how do you know which one is right for you? We tested the top brands to find the best omega-3 supplements.
Types of Omega-3
- EPA: Best for heart health and reducing inflammation
- DHA: Crucial for brain health and eye function
- ALA: Plant-based, but conversion to EPA/DHA is limited
Our Top Picks
#1 Nordic Naturals Ultimate Omega
The gold standard. Third-party tested for freshness and purity. High EPA/DHA in bioavailable triglyceride form. Fresh lemon flavor eliminates fishy burps.
#2 NOW Foods Ultra Omega-3
Best value. High potency at an affordable price. Enteric coating reduces fishy aftertaste.
#3 Viva Naturals Omega-3 Fish Oil
Wild-caught Alaskan salmon source. Sustainable and eco-friendly. Great for the environmentally conscious.
Fish Oil vs Krill Oil
Krill oil's omega-3s are bound to phospholipids, which some studies suggest may be more bioavailable. However, fish oil typically provides more omega-3 per capsule at a lower cost.
Plant-Based Options
Algae oil is the best plant-based omega-3 source. It's the only vegan source of DHA/EPA and is more sustainable than fish oil. Great for vegetarians and vegans.
