Optimal Performance Range

Meaning

Optimal Performance Range defines the precise, individualized physiological zone for a given biomarker—such as a hormone level, metabolic marker, or vital sign—that correlates directly with the subjective experience of peak health, vitality, and functional capacity. This range often resides within the statistical reference range but is tailored to the individual’s genetics, age, and clinical goals, moving beyond the mere absence of disease to a state of superior physiological function. It represents the target endpoint for all clinical optimization protocols.
