How much omega-3 should you take?

August 3, 2009 Researchers looked at the effectiveness of fish oil in reducing the risk of heart attacks. They found that 500 milligrams of omega-3 fatty acids a day will help protect healthy people against heart disease. Those with a history of heart disease should aim for 800 to 1000 milligrams a day.

Healthy people can meet the recommendation by eating two meals a week that contain fish like salmon, trout or tuna.

Fish oil supplements are another way to get omega-3's into your diet.

But you should talk to your doctor first.

The guidelines are published in the Journal of the American College of Cardiology.
