Evidence check: Cortisol senken in the context of Wechseljahre

The question of lowering cortisol during menopause is scientifically nuanced. The provided context contains no specific studies or markers on this topic. Cortisol is a stress hormone whose regulation can be affected by menopause – e.g., via estrogen decline, sleep disruption, and psychosocial factors. Direct-to-consumer tests (DNA, saliva, microbiome) cannot reliably measure cortisol or provide personalized reduction strategies. Evidence for supplements like ashwagandha, magnesium, or adaptogens is mostly mechanistic or from small studies; large clinical outcome trials are lacking. Proven approaches include stress management, exercise, sleep hygiene, and medically supervised hormone therapy if indicated. Without concrete data from the given context, the evidence level is rated as 'unclear'. Caution against overblown marketing claims is warranted.
