Evidence check: Cortisol senken in the context of Blutzucker

The idea that lowering cortisol can improve blood sugar is physiologically plausible but not well-supported by the evidence provided. Cortisol is a stress hormone that increases hepatic glucose production and reduces insulin sensitivity; chronically elevated levels are linked to higher blood glucose. However, the given context lacks direct studies or validated biomarkers showing that reducing cortisol through supplements or lifestyle changes reliably lowers blood sugar in a clinically meaningful way. Consumer tests (e.g., saliva cortisol) are available but have limited diagnostic value due to diurnal variation and lack of standardization. The evidence grade is 'mechanistic/unclear'. No specific sources from the provided context address this combination. Caution: Do not rely on self-testing alone; consult a healthcare professional for personalized advice.
