Omega-3 Fatty Acids and Atrial Fibrillation Risk

Recent research indicates that omega-3 fatty acids, specifically DHA and EPA found in fish oil supplements, may increase the risk of atrial fibrillation (irregular heartbeat) among healthy individuals. This observational study followed over 415,000 subjects, revealing that while omega-3 supplementation could benefit those with existing cardiovascular issues, it posed a heightened risk for atrial fibrillation in those without such conditions. Additionally, high-dose supplementation could correlate with an increased likelihood of developing atrial fibrillation, underscoring the need for careful dosage management. Therefore, while omega-3s may have health benefits, their use should be evaluated in the context of individual cardiovascular health statuses.
