Study Finds Fish Oil Supplements May Increase Risk of Stroke and Heart Issues

A recent study published in the American Journal of Medicine has raised concerns about the potential risks associated with the regular use of fish oil supplements. The study, conducted in the United Kingdom and involving over 400,000 participants, focused on the effects of fish oil supplements on cardiovascular health.

The research, which spanned 12 years, revealed that individuals who took fish oil supplements regularly faced a heightened risk of developing atrial fibrillation and experiencing strokes if they did not have pre-existing heart conditions. On the other hand, for those with known heart disease, the supplements were associated with a lower risk of atrial fibrillation.

According to the study, the use of fish oil supplements was linked to a 13% higher risk of atrial fibrillation and a 5% increased risk of stroke among individuals without prior heart issues. However, for participants with established heart disease, the supplements appeared to have a protective effect, with a 15% lower risk of atrial fibrillation.

Experts are urging caution regarding the widespread use of over-the-counter fish oil supplements, emphasizing the importance of obtaining omega-3 fatty acids from natural food sources. Prescription versions of fish oil, such as Vascepa and Lovaza, are recommended for individuals with specific risk factors.
