wo kann man dna test machen lassen — can a microbiome test help?

DNA tests are available from many direct-to-consumer companies like 23andMe, MyHeritage, AncestryDNA, or MyBody-X. They typically analyze saliva samples for genetic variants. Important: results are often predictive, not diagnostic – an FTO variant increases obesity risk by only 1–3 kg per allele, and lifestyle factors dominate. A microbiome test can provide additional information about gut bacteria and potential influences on digestion or inflammation. However, the evidence for direct actionable recommendations is limited (mixed). Many claims are marketing-driven. Consult a doctor before changing diet or supplements based on such tests.
