New research has found that krill oil with naturally high levels of Astaxanthin and Omega-3 Phospholipids significantly reduces fasting glucose levels in healthy humans.

In collaboration with Oslo Metropolitan University and the University of Oslo, the effects of the recently launched Rimfrost krill oil on cardiovascular risk factors was investigated and compared to the intake of a similar amount omega-3 fatty acids from fish.

“We are very satisfied with this long-term collaboration and that we manage to show that krill oil is effective in reducing fasting plasma levels of glucose. To our knowledge this has not been shown in humans before, however, studies in animal have predicted this effect,” said Dr Inge Bruheim, research manager at Norwegian biotech company Rimfrost. “These interesting results will be investigated further in new clinical trials focusing on prevention of type 2 diabetes.”

Omega-3 fatty acids

36 healthy subjects with fasting TG levels of 1.3-4 were recruited and randomised to receive either krill oil, fish or placebo for 8 weeks. Intake of both krill oil and fish increased plasma levels of omega-3 fatty acids as expected, confirming that krill oil is a bioavailable source of omega-3 fatty acids.

The astaxanthin rich krill oil reduced fasting glucose, which is important as glucose level is strongly associated with CVD risk. Krill oil also altered the peripheral blood mononuclear cell mRNA expression of genes involved in glucose metabolism.

The study has been completed and published in the Journal of Nutritional Sciences.
