wieviel magnesium um cortisol zu senken — what are common causes?

The question of the optimal magnesium dose to lower cortisol lacks a clear scientific consensus. Magnesium modulates the hypothalamic-pituitary-adrenal (HPA) axis, and some studies suggest that supplementation with 200–400 mg of magnesium (preferably as magnesium glycinate or citrate) can modestly reduce cortisol levels in individuals with low magnesium status. Effects are moderate and depend on baseline levels; additional intake in replete individuals likely provides no further benefit. Common causes of elevated cortisol include chronic psychological stress, sleep deprivation, shift work, excessive caffeine or alcohol intake, and medical conditions such as Cushing's syndrome. Magnesium deficiency itself can be both a cause and consequence of stress, as stress increases urinary magnesium excretion. Common causes of magnesium deficiency include a diet low in magnesium, gastrointestinal disorders (e.g., Crohn's disease), type 2 diabetes, alcoholism, and use of proton pump inhibitors. Evidence is based mainly on observational and small intervention studies; serum magnesium is a poor marker of total body stores. Always consult a physician before supplementing, especially in renal impairment.
