Omega-3 fatty acids are a type of unsaturated fatty acid that's thought to reduce inflammation throughout the body, a contributing factor to coronary artery disease. However, some studies haven't found a benefit. More research is needed.

• Fish and fish oil. Fish and fish oil are the most effective sources of omega-3 fatty acids. Fatty fish — such as salmon, herring and light canned tuna — contain the most omega-3 fatty acids and, therefore, the most benefit. Fish oil supplements may offer benefit, but the evidence is strongest for eating fish.
• Flax and flaxseed oil. Flax and flaxseed oil also contain beneficial omega-3 fatty acids, though studies have not found these sources to be as effective as fish. The shells on raw flaxseeds also contain soluble fiber, which can help with constipation. More research is needed to determine if flaxseed can help lower blood cholesterol.
• Other dietary sources of omega-3 fatty acids. Other dietary sources of omega-3 fatty acids include canola oil, soybeans and soybean oil. These foods contain smaller amounts of omega-3 fatty acids than do fish and fish oil, and evidence for their benefit to heart health isn't as strong.

Other supplements may help reduce your blood pressure or cholesterol level, two contributing factors to coronary artery disease. These include:

• Alpha-linolenic acid
• Barley
• Cocoa
• Coenzyme Q10
• Fiber, including blond psyllium and oat bran (found in oatmeal and whole oats)
• Garlic
• Plant stanols and sterols (found in supplements and some margarines, such as Promise, Smart Balance and Benecol)

Always talk to your doctor before adding a new over-the-counter medication or supplement to your treatment plan. Some drugs and supplements can interfere with other medications and cause side effects or make them less effective.
