High-Quality Omega 3 – Easy to Take, No Fishy Aftertaste
Size: 90 Count (Pack of 1)
I’ve been using Qunol’s Advanced Omega 3 Krill and Fish Oil Complex, and it’s one of the better omega supplements I’ve tried. The capsules are easy to swallow, and I haven’t experienced any fishy burps or aftertaste. The blend of krill and fish oil feels well-formulated, and the claim of better bioavailability makes sense since I notice benefits with fewer capsules compared to standard fish oil.
I like that it combines the strengths of both krill and fish oil—EPA and DHA support heart, brain, and joint health, while the added phospholipids from krill oil may improve absorption. The softgels are also smaller and easier to take than many large fish oil pills.
Pros:
Combines krill and fish oil for balanced omega support
No fishy aftertaste or burps
Smaller, easy-to-swallow softgels
Formulated for better absorption
Cons:
Pricier than standard fish oil supplements
Bottle size could be larger for daily users
Overall, this is a premium omega 3 supplement that’s worth it if you want high absorption and a cleaner experience. A reliable option for long-term heart and brain support.
