Upper-Optimal Range

Meaning

The Upper-Optimal Range defines the highest segment of a physiological or hormonal reference interval that is consistently associated with peak health, performance, and longevity benefits for a specific individual, while still remaining safely below the threshold for adverse effects. This range is distinct from the broader, statistically derived “normal range” used in conventional medicine, which often includes values that are merely non-pathological but not necessarily ideal for peak function. Achieving this range is a key goal in precision hormonal optimization.
