The standout feature of this supplement is its phospholipid structure, which allows your body to absorb omega-3s more efficiently than the triglyceride form found in most fish oils.

Buying Guide
Absorption and Bioavailability
One of the biggest distinctions between fish oil and krill oil is how your body absorbs them. Krill oil carries its omega-3s in a phospholipid form, which is more readily absorbed by your cells compared to the triglyceride form in most fish oils. This means you may need a lower dose of krill oil to achieve similar omega-3 levels in your blood.
Products like Kori Krill Oil Omega-3 Supplement EPA & DHA emphasize this phospholipid advantage, offering superior absorption without the fishy aftertaste. For more on how omega-3s support circulation, see our guide on supplements for healthy blood flow.
Purity and Sustainability
Sourcing matters for both potency and environmental impact. Krill is harvested from the pristine waters of Antarctica, and brands like Bronson and MegaRed prioritize sustainable harvesting practices. This ensures a clean product with minimal risk of contaminants.

Additional Nutrients: Astaxanthin and Choline
Krill oil naturally contains astaxanthin, a powerful antioxidant that protects the omega-3s from oxidation and offers anti-inflammatory benefits. Some krill oil supplements also provide choline, which supports brain and liver health.
For example, Kori Krill Oil Omega-3 EPA DHA delivers 70 mg of choline per serving, adding value beyond standard omega-3s. If you are exploring comprehensive stacks, see our comparison of omega 3 CoQ10 magnesium vs omega 3 CoQ10.
No Fishy Aftertaste
A common complaint with fish oil is the unpleasant burping or fishy aftertaste. Krill oil’s phospholipid structure and the presence of astaxanthin reduce this issue significantly. Many users find krill oil easier to tolerate, which improves consistency in supplementation.
