was kostet eine genanalyse — what can you do yourself?

The cost of a genetic analysis (e.g., from MyBody-X) typically ranges from $100 to $300 depending on the scope (metabolism, microbiome, nutrigenetics). What you can do yourself: Results can reveal small genetic tendencies like caffeine metabolism or fat processing, but weight and health are primarily lifestyle-driven. Without medical guidance, you should not make drastic diet or supplement changes based solely on a DNA test. The evidence is mostly observational/GWAS, not strong clinical trials. For medication-related questions (e.g., antidepressants), consumer tests are often insufficient – clinical pharmacogenetic testing is recommended. Use the test as a conversation starter with a doctor, not a self-diagnosis tool.
