What should I know about was ist stoffwechselanalyse?

A metabolism analysis (Stoffwechselanalyse), such as offered by MyBody-X, is a lifestyle test examining genetic variants related to energy, nutrient, and neurotransmitter metabolism. Typical genes include COMT (rs4680, 'warrior/worrier'), LEPR (rs1137101, leptin receptor), and FUT2 (rs1047781, vitamin B12 metabolism). Results indicate how your body processes substances like caffeine, fats, or B vitamins. Crucially, these tests are not medical devices. They cannot diagnose disease or replace a doctor, and under German GenDG, health-related genetic testing requires physician involvement. Evidence ranges from GWAS data (e.g., COMT) to population frequencies (e.g., LEPR). A positive finding indicates a genetic predisposition, not a disease. Many effect sizes are small, and clinical relevance is often unclear. Always consult a healthcare professional before making dietary or supplement changes.
