You stand in the supplement aisle, a bottle of krill oil in one hand and cod liver oil in the other. Both promise omega-3 benefits, but which one truly fits your body’s needs? This guide breaks down the key differences between krill oil and cod liver oil, reviews three top products, and helps you make an informed choice. If you are also weighing other omega-3 options, see how they compare in our omega 3 vs magnesium article.
Quick answer: Krill oil is absorbed more efficiently than cod liver oil due to its phospholipid form, but cod liver oil provides vitamins A and D. The Dr. Berg Omega-3 Cod Liver Fish Oil suits those wanting a clean, high-potency cod liver oil with no fishy aftertaste. Focus on absorption efficiency versus nutrient density when choosing.
Pros
- High-quality wild-caught Icelandic cod liver oil
- Pleasant lemon taste with no fishy aftertaste
- Extensive lab testing for purity and potency
- Clean label with no unnecessary additives
- Supports multiple aspects of wellness
Cons
- Modest omega-3 content per softgel may require multiple capsules for higher daily needs
- Lemon flavor may not appeal to everyone, and softgel size is unspecified
- Limited customer reviews so far, so long-term feedback is not yet established
The Dr. Berg Omega-3 Cod Liver Fish Oil Softgels offer a premium daily supplement derived from wild-caught Icelandic cod. Each softgel provides 240 mg of omega-3s, including 110 mg EPA and 125 mg DHA, to support cardiovascular, cognitive, immune, and eye health. This product is ideal for health-conscious individuals who want a clean and effective omega-3 source without the usual fishy drawbacks.
What sets this supplement apart is its naturally lemon-flavored formula, which masks the fishy taste and prevents unpleasant burps. The softgels are easy to take and leave no lingering aftertaste, making them a great option for daily use. Real-world performance is enhanced by this pleasant flavor, encouraging consistent supplementation.
Quality control is a top priority, as every batch is tested four times, including double third-party heavy metal screening.

This rigorous process ensures verified purity and potency, giving users confidence in the product's safety and effectiveness.
The product is free from GMOs, preservatives, hexane, and unnecessary fillers, aligning with a clean-label philosophy.

Buying Guide
Omega-3 Absorption: Phospholipids vs Triglycerides
Krill oil delivers its EPA and DHA in phospholipid form, which your body absorbs more efficiently than the triglyceride form found in cod liver oil. This means you may need a lower dose of krill oil to achieve the same omega-3 levels. For a deeper look at how omega-3s compare with other nutrients, read omega 3 vs plant sterols.
Cod liver oil, however, has a long history of use and is well documented. The choice between the two often comes down to personal preference and how your body responds.
Nutrient Profile: Vitamins and Antioxidants
Cod liver oil naturally contains vitamins A and D, which support immune function and bone health. Krill oil lacks these vitamins but provides astaxanthin, a powerful antioxidant that protects the oil from oxidation and offers additional cellular support. If you are focused on heart and circulation benefits, check out supplements for healthy blood flow.
Purity and Sourcing
Both types of oil should come from clean, sustainable sources. Wild-caught Icelandic cod and Antarctic krill are among the best options. Look for third-party purity verification and avoid products with unnecessary fillers. The omega 3 vs aged garlic comparison also discusses sourcing and quality.
Taste and Aftertaste
Many people dislike the fishy burps from cod liver oil. Krill oil is generally gentler on the stomach and less likely to cause reflux. Some cod liver oils, like the lemon-flavored Dr. Berg product, are formulated to minimize aftertaste. If digestive comfort is a priority, you might also explore Digestive Health supplements.
Final Thoughts
After reviewing the key differences, our recommendation comes down to your specific health goals. If you want a clean, high-potency cod liver oil with vitamins A and D and no fishy aftertaste, choose Dr. Berg Omega-3 Cod Liver Fish Oil 60 Softgels. For superior absorption and a concentrated phospholipid form with added astaxanthin, go with Kori Krill Oil Omega-3 EPA DHA. Both are excellent choices, but the right one depends on whether you prioritize nutrient density or absorption efficiency.
