The European Medicines Agency (EMA) has issued warnings about dietary supplements that contain omega-3 fatty acids. Research has linked these supplements to an increased risk of arrhythmias, which are irregular heartbeats. This concern has been reported by reputable newspapers and health authorities as they review the latest findings on heart rhythm disorders and the safety profile of common supplements.

Elevated fat in the bloodstream is a recognized risk factor for both stroke and heart attack. Some scientific data suggest that omega-3 fatty acids can help lower certain fat measures in the blood. Yet the EMA cautions that recent studies indicate the ethyl esters form of omega-3s may raise the likelihood of developing atrial fibrillation. Atrial fibrillation causes the heartbeat to become irregular and can beat rapidly, which in turn heightens the risk of stroke and heart attack. The message from health agencies emphasizes careful evaluation of benefits and risks when using these products, especially for individuals with existing heart concerns.

The agency notes that the risk of atrial fibrillation appears to be higher when people take about four grams of omega-3s daily. Typical over‑the‑counter omega-3 products often contain lower doses, so the chance of a serious arrhythmia is generally smaller for most consumers. Nevertheless, manufacturers of high‑dose omega-3 supplements are advised to clearly communicate any potential risk of arrhythmia on product labels to help consumers make informed choices.

There has been a long-standing discussion about the side effects associated with cholesterol-lowering medications, particularly statins. Some discussions have emphasized myths about their safety and potential adverse effects. While statins play a role in reducing cholesterol, individuals should consult healthcare professionals regarding their own health needs before making changes to medication or supplement use. It remains important to balance potential benefits with possible risks when considering any therapy for heart health.
