Fish oil is a a source of omega-3 fatty acids. It reduces triglycerides and a more slight reduction in blood pressure in hypertensives. It seems to notably reduce the symptoms of depression and improve some painful, inflammatory conditions.

Findings show omega-3 fatty acids may help to:

• Lower blood pressure
• Reduce triglycerides
• Slow the development of plaque in the arteries
• Reduce the chance of abnormal heart rhythm
• Reduce the likelihood of heart attack and stroke
• Lessen the chance of sudden cardiac death in people with heart disease

The American Heart Association (AHA) recommends that everyone eats fish (particularly fatty, coldwater fish) at least twice a week. Salmon, mackerel, herring, sardines, lake trout, and tuna are especially high in omega-3 fatty acids. While foods are your best bet for getting omega-3s in your diet, fish oil supplements are also available for those who do not like fish. The heart-healthy benefits of regular doses of fish oil supplements are unclear, so talk to your doctor to see if they're right for you. If you have heart disease or high triglyceride levels, you may need even more omega-3 fatty acids. Ask your doctor if you should take higher doses of fish oil supplements to get the omega-3s you need.
