Are all omega-3s created equal?
Number 8 on our list of most-read science articles for the year goes to our coverage of a study from Nutrasource Diagnostic Inc. (NDI), which concluded that the manufacturers' recommended doses of omega-3 fatty acids from different sources may have different efficacies when it comes to heart health benefits.
Writing in Lipids in Health and Disease the NDI researchers reported that recommended doses of fish oil with omega-3s in the concentrated triglyceride form produced the greatest cardiovascular disease risk reduction, compared with fish oil with omega-3s in the ethyl ester form, salmon oil with omega-3 in the (non-concentrated) triglyceride form, or krill oil with omega-3s in the phospholipid form.
“This study has shown that for segments of the population hoping to reduce their risk of developing elements of CVD, a judicious decision regarding the type and daily dose of omega-3 supplement will be important,” wrote NDI’s Maggie Laidlaw, Carla Cockerline, and William Rowe .
“It is clear that not all omega-3 supplements are created equal, at least in terms of CVD risk reduction.”
