- A critical conceptual distinction in ageing research is between lifespan (total duration of life) and healthspan (duration of disease-free, functionally intact life). These are related but distinct endpoints, and interventions that extend lifespan without improving healthspan — creating longer periods of frailty and disease — represent a different value proposition from those that compress morbidity while maintaining or extending life.
- Epitalon’s healthspan research has focused on cancer incidence reduction (tumour biology suppression through telomere integrity and immune surveillance), circadian health (melatonin restoration reducing circadian disruption-associated disease risk), and immune function preservation (immunosenescence delay). These are primarily disease-prevention oriented healthspan effects.
- MOTS-C’s healthspan research has focused on functional metrics: preservation of insulin sensitivity (metabolic health), skeletal muscle function and grip strength (physical capacity), exercise tolerance (cardiorespiratory fitness), and body composition (lean mass preservation, adiposity reduction). These are primarily functional capacity-oriented healthspan effects that directly map onto the frailty and functional decline dimensions most important for quality of life in older adults.
