We are often asked about the role of fish oil, or omega-3 fatty acids in general, for the prevention of heart and circulatory disease. I posted a video addressing this question on the video blogging site Vidoyen.com (clinic here to review). This video addresses the largest research study to date looking specifically at the role of fish oil and prevention. Unfortunately, it did show that the positive role of fish oil may be less than suggested in the past, but there could be a role for specific patients. As always, yo should talk to your doctor about all of your supplements, to help learn which may play a role for your specific health conditions (and to ensure that there are no unwanted interactions with other medications or health conditions).
