People who already have coronary artery disease, notably those who have had a heart attack.
There is solid evidence that omega-3s can help protect them. Recently the AHA started recommending 1 gram a day of omega-3s, preferably from fish, for these people, with their doctors' approval. That's the amount in a serving of fatty fish, such as 3 ounces of salmon. But most people don't eat fish every day, and many choose less-fatty fish (it takes 12 ounces of canned tuna or 7 ounces of flounder to supply 1 gram of omega-3s).
Moreover, since fish may contain mercury, it is advised limiting fish intake to 12 ounces a week, on average. So to get enough omega-3s without going overboard on fish, people with heart disease are taking fish oil supplements on days when they don't eat fish.Triglycerides in the blood increase the risk of heart disease. It is well known that omega-3s help lower triglycerides. The AHA recommends 2 to 4 grams a day from supplements for people with high triglycerides, but only under the care of a physician
Omega-3s may help relieve the inflammatory symptoms of such auto-immune diseases by suppressing the immune response. Thus, they can help reduce the joint pain and swelling of rheumatoid arthritis. The Arthritis Foundation says that fish oil supplements are worth trying. Clinical studies suggest taking about 3 grams of omega-3s a day.
