Age Reversal Proxy

Meaning

An Age Reversal Proxy is a measurable biological marker or composite score used in longevity medicine to indirectly assess the degree of biological age deceleration or apparent reversal. This term acknowledges the current clinical inability to truly reverse chronological aging, instead focusing on quantifiable improvements in biological metrics. Clinicians use these proxies, such as epigenetic clocks or telomere length, to gauge the efficacy of therapeutic interventions on the aging process. It serves as a practical, actionable indicator of systemic rejuvenation.
