wieviel magnesium um cortisol zu senken — what symptoms are typical?

The question about how much magnesium to lower cortisol and what typical symptoms are cannot be answered from the provided context. The context covers DNA variants (COMT, ADH1B, SOD2, MTNR1B) and hormone tests, but not magnesium. Generally, magnesium may modulate the HPA axis and cortisol release, but evidence for a specific dosage to reduce cortisol is weak, mostly mechanistic or from small observational studies. Typical symptoms of high cortisol include sleep disturbances, weight gain (especially abdominal), fatigue, irritability, high blood pressure, and impaired immunity. However, these are non-specific. High magnesium doses (e.g., >400 mg/day) should be taken only under medical supervision due to risks of diarrhea, nausea, and rare cardiac effects. Without relevant sources in the context, no evidence-based dosage can be given. The evidence rating is 'unclear'.
