Krill Oil Has Beneficial Effect On Obesity

OSLO, Norway—Krill oil has beneficial effects on obesity-related disorders, according to a recent study by Aker BioMarine that researched the suppression of fat accumulation and prevention of weight gain in rats when krill oil was added to a high-fat diet (PLoS ONE 7(6): e38797). Researchers from the  University of Salento, Lecce, Italy, performed the study where they investigated the effect of feeding rats a low-fat diet or a high-fat diet with or without krill oil for 12 weeks.

The results reported  krill oil has a strong capability to suppress hepatic steatosis induced by a high-fat diet administered to rats. The addition of a low amount of krill oil (2.5 percent) to a diet containing a large excess of fat (35 percent) efficiently prevented the accumulation of triglycerides and cholesterol inside rat hepatocytes.

"This study is one of several studies documenting the beneficial effects of krill oil on obesity-related disorders," said study author Lena Burri, Ph.D.  "This study, however, reveals further mechanisms behind the beneficial effect of krill oil and describes a beneficial regulation of enzymes involved in lipid metabolism as well as an improved mitochondrial function."

In another recent study, Aker BioMarine's krill powder was found to benefit lipid metabolism and decrease inflammation. Supplementation  of krill powder in  mice increased degradation of fatty acids and reduced the generation of fat.
