A research group based in Italy has found that krill oil may be more efficient in activating fat metabolism than fish oil. Their research has been published in the Journal of Animal Physiology and Animal Nutrition.
Krill oil supplier Aker Biomarine ASA (Oslo, Norway) broke the news to Nutritional Outlook, noting that the findings confirm previous work on animal models and obesity.
Rats were fed diets consisting of 2.5% krill oil, 2.5% fish oil, or control treatment. Enzymes related to fat metabolism were measured; according to Aker Biomarine, although fish oil and krill oil both encouraged beneficial responses, the effect of krill oil was “more pronounced”-especially during shorter feeding periods of two to three weeks.
Rats on diets of krill oil showed 20% fewer triglycerides and 33% less cholesterol compared to control. Lower levels of improvements were observed with fish oil (10% fewer triglycerides and 21% reduced cholesterol compared to control).
“These studies confirm the beneficial effects of krill oil on liver lipid levels that we have previously seen in two different animal models of obesity,” said Kjetil Berge, PhD, Aker Biomarine director of research and development. “The study elucidated the mechanism behind the beneficial effects of omega-3 supplementation, by demonstrating regulation of lipid synthesizing enzymes. This study gives us a foundation to study cellular mitochondrial processes in more detail in future studies.”
Krill oil is marketed as a marine ingredient high in natural levels of the omega-3s DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid).
Aker Biomarine is currently the only krill oil supplier with Marine Stewardship Council (MSC) certification for sustainable fishing practices.
Recent animal study finds that Lysoveta may help reduce neonatal brain injury
July 17th 2024A recent animal study found that lysophosphatidylcholine (LPC)-bound omega-3 long-chain polyunsaturated fatty acids (LCPUFAs), marketed as Lysoveta by Aker BioMarine, protected against neonatal hypoxic-ischemic (HI) brain injury in mice.
Krill oil supplementation raises Omega-3 Index of Lupus patients in recent study
July 16th 2024The study was conducted at 20 research centers in the United States by Aker BioMarine and the Lupus Clinical Investigators Network with oversight by Lupus Therapeutics, the clinical research affiliate of the Lupus Research Alliance.
Meta-analysis does not find increased risk of bleeding events from omega-3 PUFA consumption
July 8th 2024Researchers reviewed 11 studies and found that there was no difference in the incidence of bleeding events between patients receiving omega-3 PUFAs and those not receiving them. High dose EPA consumption was associated with an elevated but modest risk.
