Physiological Range

Meaning

The physiological range is the optimal, functional concentration or activity level of a biochemical substance, hormone, or physiological parameter necessary for the maintenance of health and peak homeostatic function within a living organism. Unlike the broader, statistically derived reference range, the physiological range is often a narrower, more individualized target that correlates directly with symptomatic relief, well-being, and reduced disease risk. Clinicians in hormonal health aim to keep patients’ biomarkers within this precise, individualized zone.
