Study: Omega 3 No Help for Heart Disease

Supplements containing omega-3 fatty acids, the oils abundant in fatty fish, are ineffective for the prevention of heart disease, a large review of randomized trials has found.

The analysis, in JAMA Cardiology, pooled data from 10 randomized trials in people who had had cardiovascular disease or were at high risk for it. There were 77,917 people in the trials, 61 percent men, and their average age was 64. Studies lasted, on average, 4.4 years, and the dose of omega-3’s ranged from 226 to 1,800 milligrams a day.
