Krill oil may help lower cholesterol RESEARCH
A study published in Nutrition Research shows that krill oil may help lower triglyceride levels. The study investigated the effects of Superba krill on blood lipids in subjects with "borderline high" or "high" triglyceride (TG) levels.
A total of 300 volunteers were divided into five groups and supplemented with krill oil at 0.5, 1, 2, or 4 g/day or placebo (olive oil). The subjects included in the study had blood TG values of 150–499 mg/dL. Blood lipids were measured at baseline, 6 weeks, and 12 weeks of treatment.
Relative to subjects in the placebo group, those administered krill oil had a statistically significant 10.2% reduction in serum TG levels. Moreover, low density lipoprotein cholesterol (LDL-C) levels were not increased in the krill oil groups relative to the placebo group, an important finding considering an increase in LDL-C has been observed in some fish oil trials.
The researchers noted that because of the individual fluctuations of TG concentrations measured, a study with more individual measurements per treatment group is needed to increase the confidence of these findings.
