Krill Oil
Krill Oil
Snapshot
Krill oil is a marine lipid supplement derived from Antarctic krill (Euphausia superba), rich in omegaโ3 fatty acids (EPA, DHA) bound to phospholipids, plus the antioxidant astaxanthin, supporting cardiovascular, cognitive, and joint health.
ย
What is Krill Oil?
Krill oil is extracted from small crustaceans called Antarctic krill. Unlike fish oil, its omegaโ3s are primarily in phospholipid form, which may enhance absorption and bioavailability.
Where It Comes From
Harvested under sustainable quotas in Antarctic waters, krill are collected, processed onโship to remove water and impurities, and extracted using gentle methods to preserve phospholipids and astaxanthin content.
Key Nutrients & Compounds
Krill oil supplies EPA and DHA esterified to phosphatidylcholine, the potent antioxidant astaxanthin, and minor phospholipids and sterols. This composition supports membrane integration and oxidative stability.
Health Benefits
Phospholipidโbound EPA and DHA support heart health by reducing triglycerides, improving lipid profiles, and promoting healthy blood vessel function. They also promote cognitive function and joint comfort, while astaxanthin provides antioxidant defense.
Recommended Dosage
Typical doses range from 500โฏmg to 1,000โฏmg of krill oil per day, providing 150โ300โฏmg combined EPA and DHA. Astaxanthin content (0.1โ0.5โฏmg) adds antioxidant support.
How to Use It
Take krill oil softgels with meals to enhance absorption. Store in a cool, dark place to preserve astaxanthin and prevent oxidation.
Who Should Use It?
Ideal for individuals seeking sustainable marineโbased omegaโ3s with enhanced bioavailability and antioxidant protection. It benefits those supporting cardiovascular, cognitive, or joint health.
Possible Interactions or Cautions
May increase bleeding risk when combined with anticoagulants or antiplatelet drugs. Mild gastrointestinal discomfort or fishy aftertaste can occur. Individuals with shellfish allergies should avoid krill oil.
Final Thoughts
Krill oil offers a unique, phospholipidโbound source of omegaโ3s and astaxanthin, providing multiโfaceted support for heart, brain, and joint health. When chosen from certified sustainable sources, itโs an excellent addition to any wellness regimen.
