A study published in the April 2, 2013 Annals of Internal Medicine, showed a positive association between higher levels of serum omega-3 fatty acids and reduced risk of death, primarily from heart disease. While there are several weaknesses in the study, such as only measuring the serum omega-3 at the beginning of the study, there are some interesting points. The authors found that DHA was more important than EPA, two of the most talked about omega-3 fatty acids, in preventing cardiovascular death. The take home message here is to not just supplement with EPA (there is now even an EPA-only prescription drug), but to use a balanced formula. I like to include DHA, EPA, as well as GLA. Together they have a powerful anti-inflammatory effect.
