Vitality Trajectory

Meaning

Vitality Trajectory is a conceptual framework in longevity medicine that describes the projected path and rate of decline or improvement in an individual’s physical and mental energy, cognitive resilience, and overall quality of life over time. This crucial metric moves beyond mere lifespan, focusing intensely on healthspan—the number of years lived in a state of high functional capacity and good health—and is a key indicator of successful aging and effective wellness interventions. A positive trajectory reflects successful, proactive management of biological aging and hormonal health.
