Find out how old your body really is - based on 10 evidence-linked biomarkers. Takes 3 minutes.
📋 Based on published longevity biomarker research • 7,400+ assessments completed
This calculator uses 10 lifestyle and physiological inputs - each weighted by its effect size from clinical research. Your biological age is your chronological age adjusted by the cumulative impact of these factors.
Key inputs and their evidence base: Resting heart rate (cardiovascular aging proxy, linked to all-cause mortality in HUNT study), sleep quality (Walker et al. 2019), physical activity level (NEJM 2014 PA-mortality dose-response), dietary quality (Mediterranean diet adherence studies), chronic stress (telomere shortening research, Epel et al.).
This tool provides an educational estimate, not a medical diagnosis. For clinical biological age testing, consider epigenetic methylation clocks (GrimAge, PhenoAge) or comprehensive biomarker panels.
