What can the DNA Stoffwechseltest tell you — and what not?

The MyBody-X DNA metabolism test analyzes selected genetic variants linked to the metabolism of nutrients, caffeine, drugs, and certain risk factors (e.g., fatty liver, lipid metabolism). It can provide clues about genetic predispositions, such as CYP1A2 status for caffeine clearance or CYP2C19 variants for drug metabolism. However, effect sizes are generally small: carrying a risk allele (e.g., in GCKR) does not mean you will develop a disease – lifestyle, diet, and environment are far more influential. The test does not replace medical diagnostics: it does not measure current blood biomarkers, hormones, or metabolic products. Pharmacogenetic results (e.g., CYP2D6 poor metabolizer) can be clinically actionable, but DTC tests often miss rare alleles; professional follow-up is essential. For skin-related concerns like glycation or collagen, the test offers no direct information. In summary: the test provides interesting but limited insights into genetic predispositions – it is a tool for personalized lifestyle choices, not a medical assessment.
