What role does Pharmakogenetik Medicheck play in Langlebigkeit?

Pharmacogenetics (PGx) like the Medicheck analyzes genetic variants affecting drug metabolism. Its direct role in longevity is indirect: by preventing adverse drug reactions and optimizing efficacy, it can improve quality of life and reduce iatrogenic harm. The provided context (FTO, MC4R, GCKR, FOXO3) covers nutrigenetics and general risk variants, not specific PGx markers. There is no strong evidence that a PGx test alone extends lifespan. Longevity is multifactorial—genetics (small effects), lifestyle, environment, and healthcare. PGx screening may be valuable for individuals on chronic medications, but it does not replace a comprehensive health approach. Evidence grade: marketing/unclear, as direct longevity benefit lacks clinical trial support. Caveat: avoid overinterpreting single gene effects.
