Omega-3s help preserve cognitive function and cardio-metabolic health
Better scores on blood pressure, inflammation and cognitive tests with omega-3s

Prior studies suggest omega-3s help preserve healthy cognitive function, and heart and metabolic health. Doctors said metabolic disorders such as type 2 diabetes have a link to cognitive decline but few studies explore this relationship. Here, researchers sought a connection between omega-3s, cognitive performance, and cardio-metabolic factors in healthy men and women.
In the study, 40 participants, aged 51 to 72, took a placebo or a supplement containing 1,500 mg of EPA, 1,050 mg of DHA, and 450 mg of other omega-3 fatty acids per day, in two alternating five-week phases. Doctors tested cognitive performance and measured metabolic markers after each phase.
Compared to the placebo phases, during the omega-3 phases, participants had a 5 percent decline in one marker of inflammation, had 6 mmHg lower average systolic blood pressure, an average decline in triglycerides of 16 mg per deciliter of blood, and scored better on cognitive assessment tests.
