MyBody-X angle on Magnesium Basis

Magnesium is an essential mineral involved in over 300 enzymatic reactions. MyBody-X examines genetic variants in genes such as TRPM6, SLC41A1, and CNNM2 that may influence magnesium metabolism. However, the evidence is mostly mechanistic or from small association studies; individual SNPs typically have a modest effect on serum magnesium levels. Diet, kidney function, and medication use are far more impactful. A DNA test cannot diagnose magnesium deficiency – a blood test (serum or RBC magnesium) is required. High-dose magnesium supplements without medical supervision can cause diarrhea, hypotension, or drug interactions. MyBody-X provides insights, not medical directives. If you suspect a magnesium imbalance, consult a healthcare professional. Evidence: mechanistic/gwas, with caveats.
