Dr. Hope Ricciotti, M.D. and Dr. Hye-Chun Hur, M.D., M.P.H. from Harvard Health argue that despite fish oil’s benefits, there’s no convincing evidence to recommend it, especially at high doses.
Do fish oil supplements reduce inflammation? - Harvard Health
By Hope Ricciotti, M.D., and Hye-Chun Hur, M.D., M.P.H. September 2016 Q. I've read that taking doses as high as 3,000 to 6,000 milligrams a day of a fish oil supplement may lower inflammation. If so, I'd like to take it to reduce my risk of cancer and heart disease. A. Fish oil contains omega-3 fatty acids, which are part of a healthy diet that is associated with lower levels of inflammation. Your body can't manufacture omega-3 fatty acids—eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and alpha-linolenic acid (ALA)—so it's important to get them through your diet. EPA and DHA are primarily found in fatty fish, such as salmon, tuna, and anchovies. ALA is found in plants and is available in vegetable oils, nuts, flaxseeds, and flaxseed oil.
