Objective: This study investigates the effects of fish oil supplementation on cardiovascular health.
Context: Omega-3 fatty acids in fish oil may provide cardiovascular benefits, but optimal dosing is unclear. This study examines the impact of different fish oil doses.
Approach: Systematic review and meta-analysis of randomized controlled trials on fish oil for cardiovascular risk factors.
Data Collection: Studies examining the effect of fish oil supplementation on lipids, blood pressure, arterial stiffness and other CVD biomarkers were included.
Researchers' Summary of Findings
Impact on Health: Moderate doses of omega-3 fish oil (1-2 grams/day) significantly improved triglycerides, HDL cholesterol, and other cardiovascular risk factors. Higher doses provided no additional benefit.
Health Implications: Moderate daily fish oil supplementation appears beneficial for cardiovascular health. Further research can optimize dosing regimens.
