Is Stuhlprobe useful for Sport?

Whether a stool test is useful for sports depends on context. The gut microbiome influences inflammation, immunity, and nutrient absorption, all relevant to athletic performance. However, direct evidence that stool analysis improves performance is limited. Most studies are small or mechanistic, and microbiome-based interventions (probiotics, diet) show modest effects. MyBody-X does not offer stool tests; the provided context covers DNA tests (ADIPOQ, CYP2D6) and sleep genes. For athletes, continuous glucose monitors and blood biomarkers (e.g., ferritin, vitamin D) have stronger evidence. A stool test might identify dysbiosis linked to fatigue or GI issues, but interpretation is not yet standardized. Be cautious of marketing claims that promise performance gains from microbiome data alone. Evidence: mixed – some human studies but no large trials. Sources: none from context.
