Stacking Years is an evidence-based longevity platform that aggregates peer-reviewed research and expert consensus to help people make better health decisions. Our mission is to make longevity science accessible, transparent, and actionable.
We score 55 longevity interventions using a transparent methodology: 85% scientific evidence weight — based on meta-analyses, RCTs, and cohort studies — and 15% expert consensus weight drawn from endorsements by leading physicians and researchers. Every score includes a full explanation so you can evaluate the evidence yourself.
