New study shows low-dose omega-3 intake does not raise atrial fibrillation risk

A new meta-analysis of 114,000+ participants found that low-dose omega-3 supplementation is not associated with an increased risk of atrial fibrillation, even among individuals at elevated cardiovascular risk. In contrast, high-dose prescription therapies may modestly increase AF risk in these patients.
