Since cardiovascular disease is the number one cause of death across the world, it’s important to take steps to lower our risk. Taking omega-3 fatty acids has long been thought to be part of that prevention strategy. A new study published in JAMA Network Open shows that a particular source of omega-3s, krill oil, might be an especially good way to reduce the risk. Researchers studied over 50 patients with severely high triglyceride levels in their blood and randomly assigned them to receive krill oil capsules or placeboes during the study. The patients who consumed krill oil had almost a 13 percent reduction in triglyceride levels – possibly the most important marker for cardiovascular disease risk. And krill oil did not cause an increase in LDL cholesterol.
