When is Cortisol Senioren actually useful?

The question of when cortisol testing or supplementation is useful in seniors cannot be answered from the provided context, as none of the entries address cortisol or senior-specific topics. In general, cortisol measurements (e.g., saliva, serum) are clinically indicated for suspected adrenal insufficiency, Cushing's syndrome, or therapy monitoring. In healthy seniors without relevant symptoms, such tests rarely yield actionable clinical information. Direct-to-consumer offerings that market cortisol as a 'stress marker' or 'aging indicator' often overstate the evidence. The HPA axis changes with age, but without medical evaluation and repeated measurements, single values are difficult to interpret. Evidence grade: unclear (no contextual support). Safety note: Do not self-medicate with cortisol preparations; they can impair immune function, bone metabolism, and blood glucose regulation.
