Omega-3 Heart Benefit

This review of 16 placebo-controlled omega-3 trials covered 81,073 people with previous, or higher chances of, adverse heart or vascular events. Studies ranged from one to seven years, at varying doses. Overall, compared to those who took less, those who took more than 1,000 mg per day of EPA with DHA from fish oil were 24 percent less likely to have an adverse heart or circulatory event. Among those with a previous major adverse event, taking at least 1,000 mg of omega-3 fish oil reduced chances of dying from another event by 35 percent. Doctors concluded that world health authorities recommending lower omega-3 intakes may need to update their advice.
