Nährstoff | VitalCheck Basic: which diet helps?

The MyBody-X VitalCheck Basic analyzes biomarkers or genetic variants related to nutrient metabolism. However, it cannot directly tell you which specific diet helps. Evidence for personalized diet recommendations from such tests is weak – mostly based on GWAS or mechanistic studies, not robust RCTs. A balanced, whole-foods diet (e.g., Mediterranean) is generally best. The test may indicate rough tendencies but should not replace medical advice. Beware of overblown marketing claims: effect sizes of single gene variants are small, and lifestyle factors dominate. For specific deficiencies (e.g., vitamin D, iron), blood tests are more informative than DNA tests.
