Omega-3 fatty acids, which are considered good for the brain, heart, and skin, may also have a dangerous side.
The human body cannot produce omega-3s on its own, so it is important to get them from foods such as fish, seeds, and nuts. They help reduce inflammation, protect against cognitive impairment, and support vascular health.
However, a new study by the European Society of Cardiology (ESC), published in the European Heart Journal: Cardiovascular Pharmacotherapy, has found that taking supplements high in omega-3s may cause atrial fibrillation (AFib), a dangerous condition in which the heart begins to beat irregularly.
AFib increases the risk of stroke by five times, according to doctors. The American Heart Association (AHA) also notes that the condition can lead to blood clots, heart failure, and other complications.
The researchers clarified that the greatest risk is observed in patients who already have heart problems. At the same time, they emphasized: this does not mean that you should completely abandon omega-3. This is precisely about dietary supplements, while foods rich in these acids remain beneficial.
Experts advise taking omega-3 supplements only after consulting a doctor and under medical supervision.
