A state where key biomarkers reflecting cellular and systemic function present within a range typically associated with a chronologically younger biological age, rather than one’s chronological age. This status reflects optimized endocrine signaling, robust mitochondrial function, and superior tissue resilience against senescence. We assess this by looking beyond simple metrics to integrated physiological performance indicators.
Origin
This concept emerges from the fields of gerontology and endocrinology, where the study of age-related decline necessitates defining a functional peak against which deviation can be measured. It is an aspirational term describing the outcome of successful longevity interventions targeting the hallmarks of aging. The underlying principle is decoupling chronological time from functional biological capacity.
Mechanism
Achieving this status involves modulating pathways that govern cellular repair and turnover, such as enhancing autophagy and maintaining telomere integrity. Optimal hormonal balance, particularly regarding growth factors and sex steroids, supports anabolic processes while dampening chronic inflammatory signaling. This coordinated physiological state supports tissue homeostasis over extended periods.
