Researchers from Sweden’s Karolinska Institutet and the University of Bergen, Norway, have concluded that the omega-3s in krill are advantageous for reducing high blood triglycerides. Their recently published study in Nutrition & Metabolism compared equal amounts of Superba™ krill oil and fish oil in a high-fat diet given to mice for 6 weeks. The effects on plasma and liver lipids as well as gene regulation in the liver and intestine were measured at the end of the study.
“When comparing krill and fish oil supplementation, we found differences in the metabolic regulation of genes involved in lipid degradation and synthesis,” commented author Veronika Tillander, PhD. “While fish oil mainly increased the degradation of lipids, krill oil decreased the expression of genes involved in endogenous fatty acid and cholesterol synthesis.”
Lena Burri, PhD, Director of Scientific Writing, Aker BioMarine Antarctic, added: “Even though the krill oil diet contained less omega-3 fatty acids, plasma and liver phospholipid omega-3 levels were similar in the krill and fish oil supplemented groups. Krill oil’s special combination of omega-3 fatty acids in phospholipid form may therefore represent an attractive means of managing high blood lipids.”
Explaining what these findings mean for Superba™ Krill moving forward, Tove Flem Jacobsen, Vice President of R&D and Regulatory Affairs, Aker BioMarine Antarctic, said, “This study expands our knowledge base on the beneficial effects of krill oil on lipid metabolism. And it represents an important step in strengthening krill oil’s position in the triglyceride-lowering market.”

SuperbaTM Krill is a pure, natural source of the health-promoting EPA & DHA omega-3 essential fatty acids and the naturally occurring antioxidant astaxanthin. The uniqueness of SuperbaTM Krill is that the omega-3 fatty acids are provided in phospholipid form. In vitro, in vivo and human clinical research has demonstrated the safety and efficacy of SuperbaTM Krill.
Aker BioMarine is an integrated biotechnology company dedicated to the sustainable harvest of krill and development of krill-derived biotech products. The company supplies biomarine ingredients through an optimized value chain from sea to shelf. Aker BioMarine’s SuperbaTM Krill products are provided with 100% traceability from sea to shelf. Only Aker’s krill fishery has been awarded Marine Stewardship Council (MSC) Certification.
