Fish oil does not lower the risk of cardiovascular disease or death, according to a new review in the Journal of the American Medical Association. Researchers analyzed 20 studies including 68,680 patients who used omega-3 fatty acids for an average of two years and determined that fish oil had no effect on heart-related death, heart attack, or stroke. These findings follow another recent review showing fish oil did not prevent the recurrence of heart problems among patients.
