Regular Use of Fish Oil Supplements May Increase First-Time Heart Disease and Stroke Risk

Experts claim that the advantages of fish oil supplements have not been well studied. Omega-3 fatty acid-rich fish oil is frequently used to help reduce the risk of cardiovascular disease. Nevertheless, a recent study indicates that among those in good heart health, these supplements may potentially raise the risk of heart attack and stroke. 

Study Findings

Chinese researchers discovered that heart-healthy people who used fish oil supplements were more likely than those who did not to experience atrial fibrillation and stroke. On the other hand, the supplements seemed advantageous for people who already had heart problems.

Key Points

• Fish oil users without cardiovascular disease had a 13% higher risk of atrial fibrillation and a 5% higher risk of stroke.
• Individuals with cardiovascular disease using fish oil had a 15% lower risk of heart attack progression and a 9% lower risk of heart failure progression.
• Women and non-smokers who took fish oil had a 6% higher risk of transitioning from good health to heart disease or stroke.
• Men and older individuals showed a protective effect from fish oil.

Expert Opinions

According to Dr. Adedapo Adeyinka Iluyomade, recommendations for fish oil should be made more carefully, giving preference to people who already have cardiovascular disease. To assure quality, Dr. Rohit Vuppuluri suggests utilizing prescription-grade fish oil for medicinal treatments.

Mixed Research Results

The advantages of fish oil have been inconsistently studied in the past. Some research indicates lower risks of myocardial infarction and abrupt cardiac death; nevertheless, other studies indicate no effect on cardiovascular mortality. Professionals such as Elana Natker stress that more clinical research is necessary to elucidate these results.
