How are Magnesium and Haut related?

The relationship between magnesium and skin health is biologically plausible but supported mainly by mechanistic evidence rather than robust clinical trials. Magnesium is involved in inflammation regulation, skin barrier function, and collagen synthesis. Deficiency may theoretically contribute to dry, irritated skin or heightened stress sensitivity, as magnesium modulates cortisol. However, direct causal evidence from randomized controlled trials linking magnesium intake to specific skin outcomes like elasticity, glycation, or acne is lacking. Consumer DNA tests claiming a connection via single SNPs (e.g., in TRPM6 or SLC41A1) often overstate effect sizes. Magnesium status is better assessed via blood tests (serum or whole blood). Supplementation without confirmed deficiency is not recommended and may cause gastrointestinal side effects or drug interactions at high doses. For skin health, established factors like sun protection, hydration, and overall diet are far more impactful. Evidence grade: mechanistic/insufficient.
