A study published in BMJ Medicine followed over 400,000 UK Biobank participants for 12 years to investigate the link between fish oil supplements and cardiovascular health.
Researchers found that individuals without pre-existing heart conditions who regularly took fish oil supplements had a slightly increased risk of atrial fibrillation (irregular heartbeat) and stroke.
Conversely, for individuals with pre-existing heart disease, fish oil supplements were associated with a reduced risk of heart attack and death from heart failure.
The effects of fish oil supplements varied depending on factors like gender, age, and smoking status.
It is important to note that this study was observational and does not prove causation, and further research is needed to determine the optimal dose and formulation of fish oil supplements for different populations.
The research was carried out at Sun Yat-Sen University.
