Evidence check: Darmflora MIKROBIOM-Test | Kinder in the context of Müdigkeit

The MyBody-X gut microbiome test analyzes the composition of your gut bacteria. For athletes, this is interesting because the gut-brain axis and nutrient absorption can influence performance. However, the scientific evidence for personalized recommendations from a microbiome test in healthy athletes is still weak. Most studies show associations (e.g., certain bacteria in endurance athletes) but no causal, reproducible guidelines for diet or supplements. Moreover, these tests are often not clinically validated, and results vary greatly with diet, training, and daily form. A microbiome test can serve as a curious starting point, but it does not replace established sports medicine care. Focus should remain on balanced nutrition, optimized training, and recovery. Evidence: human-moderate (association studies), but for personalized recommendations it's more mechanistic/marketing. Caveat: No randomized trials show a performance benefit from test-driven interventions.
