What role does Omega-3 Index play in Langlebigkeit?

The Omega-3 Index measures the percentage of EPA and DHA in red blood cell membranes and serves as a long-term marker of omega-3 status. Higher levels (≥8 %) are associated with reduced cardiovascular risk, lower inflammation, and better cognitive maintenance—all contributors to healthy aging. However, direct evidence that raising the Omega-3 Index extends maximum lifespan is limited to observational and mechanistic studies; robust randomized trials for longevity are lacking. The index is influenced by diet, supplementation, and genetic variants (e.g., FADS1/2), so a single test result must be interpreted cautiously. For consumers, it is a useful biomarker for monitoring omega-3 intake but not a standalone predictor of longevity. Evidence grade: human-moderate. Caveat: no strong causal proof for lifespan extension.
