wieviel magnesium um cortisol zu senken — when to see a doctor?

There is no universally established magnesium dosage to lower cortisol. Some studies suggest that magnesium supplementation can modestly reduce cortisol levels in chronically stressed individuals, but effects vary based on baseline magnesium status, stress levels, and individual physiology. Typical supplemental doses range from 200 to 400 mg of elemental magnesium per day, with higher doses increasing the risk of gastrointestinal side effects and, in people with kidney impairment, dangerous electrolyte imbalances. You should see a doctor if you experience persistent stress symptoms, sleep disturbances, high blood pressure, or unexplained weight gain—these may indicate elevated cortisol. Medical evaluation is also necessary if you have kidney disease, heart arrhythmias, or take medications like diuretics or bisphosphonates. A blood test for magnesium and cortisol can provide clarity. Consumer DNA tests (e.g., MyBody-X) are not clinically validated to assess cortisol or magnesium needs. The evidence is moderate: human studies exist but lack standardized dosing guidelines. Be cautious of marketing claims that portray magnesium as a simple 'cortisol killer.'
