On average, participants who consumed a total of 250 mg of EPH/DHA (eicosapentaenoic and docosahexaenoic acids) per day were 35 percent less likely to die of a sudden heart attack compared to those who consumed less.
In 2009, the European Food Safety Authority recommended 250 mg of omega-3 fatty acids per day and, in 2010, the U.S. recommended 8 to 12 ounces of seafood per week, which provide an average of 250 mg of EPA and DHA.
Doctors concluded that 250 mg of omega-3s per day may be a minimum target to promote cardiovascular health in the general population.
