Can Leaky Gut Test help with Müdigkeit?

Whether a Leaky Gut Test can help with fatigue is not scientifically clear. The test measures markers like zonulin in stool, proposed to indicate increased intestinal permeability. Theoretically, a compromised gut barrier might contribute to systemic inflammation and fatigue. However, robust clinical evidence linking leaky gut to fatigue is lacking; most support comes from mechanistic hypotheses and animal studies. Commercial leaky gut tests are often unstandardized and their results difficult to interpret. Fatigue has numerous causes (iron deficiency, sleep disorders, thyroid issues, psychological factors) that should be medically evaluated first. A leaky gut test may serve as a complementary wellness tool but not as a diagnostic. Without accompanying blood/stool analyses and medical assessment, its utility is questionable. Conclusion: The test does not provide proven help for fatigue; evidence is weak and marketing-driven.
