Omega‑3 Index Predicts Lifespan

Does omega-3 status influence longevity?

Yes. A higher omega-3 index is associated with longer lifespan and reduced cardiovascular risk.

Explanation

The omega-3 index measures EPA and DHA levels in red blood cell membranes, serving as a biomarker of long-term omega-3 status. Studies show that individuals in the highest quartiles live significantly longer than those with the lowest levels. Omega-3 fatty acids stabilize cardiac cell membranes, reduce arrhythmias, lower triglycerides, and dampen inflammation, all of which reduce cardiovascular risk.

Beyond heart health, omega-3s influence brain function, immune signaling, and gene expression linked to aging. Optimizing the omega-3 index through diet (salmon, sardines, walnuts, chia seeds) or supplements is an evidence-based way to extend healthspan.

Practical Emphasis: Have your omega-3 index tested to establish a baseline. Strive for two servings of fatty fish per week, and consider supplementation when dietary intake is insufficient or inconsistent.

Takeaway (Action Tip)

Eat two servings of fatty fish per week or consider omega-3 supplements if deficient.
