Millions of Americans take fish oil supplements to promote heart and vascular health. But a new analysis suggests that some consumers may not always get what they are paying for.
The new research, carried out by a testing company called LabDoor, analyzed 30 top-selling fish oil supplements for levels of omega-3 fatty acids, a group of compounds with anti-inflammatory effects. It found that six of those products contained levels of omega-3s that were, on average, 30 percent less than stated on their labels.
The research found more problems when it looked specifically at levels of two particular omega-3s that are promoted for brain and heart health: docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). Tests showed that at least a dozen products contained DHA levels that were, on average, 14 percent less than listed on their packaging.

LabDoor, which is funded in part by the investor Mark Cuban and by Rock Health, a nonprofit digital health incubator, posted its full list of rankings and results on its website.
