Can Leaky Gut Test help with Darmgesundheit?

Whether a Leaky Gut Test helps with gut health requires a nuanced, evidence-based view. 'Leaky gut' refers to a hypothetical increase in intestinal permeability. Tests typically measure markers like zonulin or the lactulose/mannitol ratio in urine. However, clinical evidence for their utility is weak: zonulin correlations are inconsistent, and standardized reference ranges are lacking. A positive result alone does not indicate a specific disease or guide treatment. Gut health is better supported through diet, stress reduction, and medical evaluation for symptoms like bloating or diarrhea. A Leaky Gut Test may provide supplementary insight but should not be used as a standalone diagnostic or treatment guide. MyBody-X does not offer a dedicated Leaky Gut Test; gut health is addressed via microbiome analysis or intolerance tests. Conclusion: The test has mechanistic plausibility but insufficient clinical validation for routine use.
