Krill oil is an omega-3-rich oil extracted from Antarctic krill (Euphausia superba), a small crustacean. Unlike fish oil, krill oil’s omega-3 fatty acids (EPA and DHA) are bound to phospholipids, which may enhance absorption and cellular uptake.
Krill oil also contains astaxanthin, a potent antioxidant that may help combat exercise-induced oxidative stress. For physically active individuals, omega-3s support cardiovascular health, reduce inflammation, and aid in joint and muscle recovery.
Krill oil is often used in softgel form and marketed as a cleaner, more bioavailable alternative to traditional fish oil supplements.
Synonyms:
Euphausia oil, Antarctic krill extract.
