22 May 2024 • A recent UK Biobank study involving 415,737 participants aged 40-69, with a median follow-up of nearly 12 years, reveals mixed effects of fish oil supplements on cardiovascular disease progression.

While regular fish oil use appeared to increase the risk of atrial fibrillation (HR 1.13) and stroke (HR 1.05) among healthy individuals, it showed protective benefits for those with existing cardiovascular conditions.

Specifically, it reduced the transition from atrial fibrillation to major adverse cardiovascular events (HR 0.92), myocardial infarction (HR 0.85), and decreases mortality in heart failure patients (HR 0.91).

This dual role underscores the need for tailored recommendations based on individual cardiovascular health status.
