Some may call it fish oil failure. In brand new research published in the Journal of the American Medical Association, a team analyzed the records of nearly 70,000 patients involved in 20 previous studies. All of the participants had regularly taken Omega-3 fatty acid supplements for their heart health benefits.

According to the data, more than 7,000 had passed away, close to 4,000 of those were from cardiac conditions and more than 1,100 from sudden death. They also tracked more than 1,800 heart attacks and nearly 1,500 strokes.

The researchers report that the numbers show that Omega-3s are not associated with a lower risk of these cardiovascular conditions or death in general.

While the FDA has approved the use of Omega-3 fatty acids as a triglyceride-lowering agent, their recommendation that a daily dose isn't justified for most people as a structured intervention. As always, talk to your doctor about what's right for you.
