What to watch with Pharmakogenetik Medicheck and Sport?

Combining pharmacogenetics (Medicheck) with sport is an emerging area but lacks robust evidence. Pharmacogenetic tests analyze drug-metabolism genes (e.g., CYP450) to guide medication dosing – useful for painkillers or asthma inhalers. In sports, marketing often claims these tests can personalize supplements or predict doping risks. However, the evidence is weak: effect sizes are small, most studies are underpowered, and DTC tests are not diagnostic. Ancestry bias (mostly European) limits applicability. While genes like ACTN3 (power/sprint) are sometimes included, their integration with pharmacogenetics is not validated. Do not use these results for performance enhancement or supplement decisions without medical supervision. The evidence grade is marketing/unclear. Caveat: consumer tests should not replace professional advice.
