Krill Oil Beat Fish Oil at Cutting Rats' Blood/Liver Fats

Results from a rat study found that krill oil reduced blood cholesterol levels and improved liver triglyceride levels more than fish oil.
 
For the six-week study, scientists at Italy’s University of Salento divided rats into three groups, and fed two groups diets that derived 2.5 percent of calories either from krill oil or fish oil.
 
The results showed two substantial advantages for krill oil:
Krill Oil Group – Blood cholesterol dropped 33 percent; liver triglycerides dropped 20 percent.
Fish Oil Group – Blood cholesterol dropped 21 percent; liver triglycerides dropped 10 percent.
 
As the authors wrote, “We believe that the present investigation opens up new possibilities regarding the use of dietary krill oil as a preventive factor for dyslipidemia [unhealthy fat/cholesterol profiles].” (Ferramosca A et al. 2011).
 
The study used the same krill oil found in our certified-sustainable Vital Red Krill Oil supplement, and no krill oil companies funded the study.
 
The new study echoes findings from a recent human trial, which found that krill oil outperformed fish oil for improving key markers of heart-health risk (see “Krill Oil Bested Fish Oil in Heart Trial”).
 
The superior effects of krill oil on the animals’ cholesterol and liver triglyceride levels were attributed to more efficient inhibition of “lipogenesis” (fat/cholesterol creation) observed in the krill oil-fed group.
