Krill Oil May Help Promote Healthy Triglyceride Levels
Krill oil is an oil derived from shrimp-like crustaceans called krill. Krill oil contains very high amounts of astaxanthin as well as the omega-3 fatty acids DHA and EPA. Researchers from Tufts University have found that supplementation with krill oil may help improve triglyceride levels.
Participants in the study included 520 adults with very high triglyceride levels. They were given 4 grams of krill oil or a placebo daily for 26 weeks. All participants were given dietary counseling. Triglyceride levels were evaluated at baseline, week 4, week 11, week 12, week 18, and week 26.
Participants in the krill oil group saw a 26% decrease in blood triglyceride levels after 12 weeks compared to a 15.1% decrease in the placebo group. By week 26, participants in the krill oil group saw a 33.5% decrease in blood triglyceride levels compared to a 20.8% decrease in the placebo group.
The largest decreases were seen in participants in the krill oil group. who were taking medication for high triglyceride levels.
A previous study found that krill oil may provide blood sugar benefits.
The study was published online ahead of print on January 6, 2022 in the journal Cardiology.
