Omega-3 and Heart Health: What the Evidence Says
Omega-3 fatty acids have been studied extensively for cardiovascular benefit, with somewhat mixed results.
What the evidence supports
Reasonably strong evidence for triglyceride reduction, with more mixed evidence for broader cardiovascular event reduction.
Food vs. supplement
Eating fatty fish directly is often recommended as a first approach, with supplements as a convenient addition rather than a replacement.
Choosing a supplement
Third-party tested products with adequate EPA and DHA content are generally recommended over lower-quality options.
Key takeawayOmega-3s show solid evidence for triglyceride reduction and more mixed evidence for broader cardiovascular benefit — eating fatty fish directly remains a well-supported first approach.
