MyBody-X angle on Magnesium Ernährung

MyBody-X DNA tests (e.g., NutriCare) analyze over 140 gene variants, including those involved in magnesium metabolism (e.g., TRPM6, SLC41A1). However, the evidence for personalized magnesium recommendations based solely on genetics is primarily mechanistic: associations exist between certain variants and magnesium levels, but no robust randomized trials demonstrate that genotype-guided supplementation improves clinical outcomes. A DNA test may suggest a genetic predisposition for low magnesium, but it does not replace direct biomarker measurement (serum/urine magnesium). The DASH diet trials (strong human evidence) show that increasing dietary magnesium from leafy greens, nuts, and whole grains can lower blood pressure – regardless of genotype. Consumers should be cautious of specific dosing advice derived only from DNA. Safety note: High-dose magnesium supplements can cause diarrhea and interact with medications; consult a physician before supplementation.
