Daiwa Krill Oil is a super antioxidant composed of pure oil derived from Antarctic krill. Krill are plentiful, tiny, bright pink, shrimp-like crustaceans. Krill oil is the only marine oil that includes a combination of three (3) key substances the human body needs to function properly: omega-3 essential fatty acids (EPA and DHA), phospholipids (an important component of the cell membranes) and antioxidants including astaxanthin (a potent carotenoid that gives krill its red-orange color). Daiwa Krill are harvested responsibly.
