Functional Health Range

Meaning

The Functional Health Range represents the optimal, narrow band of physiological values within which an individual’s biomarkers function best, often falling within but tending toward the ideal third of the broader laboratory reference range. Unlike the conventional reference range, which merely indicates the values found in 95% of the population, the functional range is clinically determined to reflect a state of optimal vitality, resilience, and freedom from subclinical symptoms. Operating within this targeted range is a key objective of proactive health management and hormonal optimization. It shifts the clinical goal from merely avoiding disease to actively pursuing peak performance.
