Many health and medical professionals recommend supplementing your diet with fish oil and a low dosage of aspirin on a daily basis. I have added these supplements to my diet as my family has a history of heart disease. However, I have wondered whether the blood thinning effects of aspirin would be multiplied in an unsafe way by adding fish oil. Dr. William Harris, former professor of medicine at the University of Missouri-Kansas City and Director of Nutrition and Metabolic Diseases Research at the University of South Dakota Health Research Foundation has reviewed the medical literature for studies that relate to this issue and concludes that “omega-3 fatty acid supplements do not increase the risk for clinically significant bleeding, even in patients also being treated with anti-platelet or anti-thrombotic [blood-thinning] medications”.

I was happy to find this article because I have been trying to find an answer to this question for some time. You can read the details of the interview with Dr. Harris at Vitalchoice.com.
