The evidence tells a more nuanced story. Several genetic variants (e.g., in TRPM6, SLC41A1, CNNM2) have been associated with small differences in serum magnesium levels – typically <0.1 mmol/L per risk allele. However, these explain only a fraction of the variation. Magnesium status is primarily determined by diet, kidney function, medications, and gut health. Direct-to-consumer tests that translate such SNPs into personalized supplementation advice overstate the evidence. No clinically validated genetic panel exists to reliably predict magnesium requirements. A blood test (serum or RBC magnesium) remains the standard. Genetics may offer a minor clue, but not a basis for supplementation decisions. Most studies are observational/GWAS with small effect sizes, and replication in diverse populations is limited. Consumers should be skeptical of bold claims.
