Why this biomarker.

Omega-3 Index is among the markers where the relationship between blood level, intervention, and outcome has been characterized across independent cohorts.

Aviado's coverage focuses on what the published evidence actually shows — effect sizes, dose-response curves, and the strength of replication — rather than on commercial claims.

Whether you're tracking your own number or simply want a cleaner map of the literature, every claim on these pages links back to primary sources.

Supplements that measurably move this marker.

Tier reflects evidence quality for moving Omega-3 Index specifically — not the supplement's broader profile. Effect sizes are typical population responses; individual variability is high.
