HbA1c
3-month average blood glucose. Levels >= 5.7% associated with cognitive decline independent of diabetes diagnosis. Aviado's reference target: < 5.7%.
Where the numbers fall.
Source: peer-reviewed reference framework, replicated across cohortsReflects the distribution observed in published surveillance cohorts.
Threshold associated with measurable benefit in the studies Aviado has reviewed.
Levels observed in long-lived populations — a reference point, not a treatment target.
Why this biomarker.
HbA1c 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 HbA1c specifically — not the supplement's broader profile. Effect sizes are typical population responses; individual variability is high.
