Myths vs facts: Pharmakogenetik Medicheck and Sport

The combination of pharmacogenetics (Medicheck) and sport is surrounded by myths. Fact: pharmacogenetic tests like Medicheck are designed primarily to predict drug responses and side effects, not athletic performance or nutrition. Some genes (e.g., ADH1B for alcohol metabolism, GSTM1 for detoxification, MTNR1B for glucose tolerance) have mechanistic or moderate human evidence, but no randomized trials show that personalized supplementation or training based solely on these variants improves performance. The myth that a DNA test can tell you whether you need more antioxidants or specific macronutrients is overblown. Evidence is mostly mechanistic or observational, not clinically validated. Caution: such tests can lead to unnecessary expenses or false reassurance. A balanced lifestyle and medical advice matter more than any single gene variant.
