Can Pharmakogenetik Medicheck help with Sport?

The Pharmakogenetik Medicheck analyzes genetic variants affecting drug metabolism (e.g., CYP450 enzymes). For sports, it could theoretically help assess tolerance to supplements or medications (e.g., caffeine, pain relievers, asthma inhalers). However, the evidence is limited: most studies are observational or mechanistic, and direct performance enhancement is not proven. Individual gene effects are small and overshadowed by lifestyle and training. The test is not a substitute for medical advice or doping regulations. Athletes seeking performance gains should rely on evidence-based training and nutrition. The predictive value of such direct-to-consumer tests is often overstated.
