Is it better to take fish oil or omega-3? No. Fish oil is an especially rich source of omega-3 fatty acids, which are also found in flaxseed, walnuts, and dark leafy greens. Research has shown that certain omega-3s reduce the risk of a second heart attack and lower heart-attack risk in healthy people. But fish oil contains other fatty acids and fats, too.
