Many people take omega-3 fatty acid supplements hoping to reduce their risk of adverse cardiovascular events. However, recent research suggests that these supplements may have little value. A group of 12,500 well-controlled diabetic patients who received 1 gram of omega-3 fatty acid or a placebo demonstrated no differences after 6 years of follow-up. These findings are consistent with a meta-analysis of patients, with or without diabetes, showing no benefit to supplementation.
PositiveTip: Save your money, as there is no compelling evidence indicating that fish-oil or omega-3 fatty acid supplementation prevents cardiovascular disease.
