was kostet eine stoffwechselanalyse — can a DNA test help?

The cost of a metabolic analysis varies widely. MyBody-X offers DNA-based metabolism tests, but the exact price is not given in the context – typical consumer DNA tests range from 100 to 300 €. Can a DNA test help? Partially. It can reliably identify certain genetic variants with moderate to strong evidence, such as lactose intolerance (LCT/MCM6), caffeine metabolism (CYP1A2), or folate processing (MTHFR). However, for optimizing overall metabolism or athletic performance, the evidence is weak. Most analyzed SNPs have small effect sizes, and current research does not support using DNA tests alone to tailor a diet for performance. The evidence grade is 'gwas/mechanistic' – based on genetic associations, not clinical trials. MyBody-X explicitly states their tests are for nutritional/lifestyle purposes, not medical diagnosis. For a comprehensive metabolic assessment, blood biomarkers (e.g., glucose, lipids, thyroid hormones) are more actionable. A DNA test can be a fun, informative add-on, but should not replace professional medical advice or a balanced diet. Be cautious of marketing claims that overstate the benefits.
