Can Mikrobiom Test help with Darmgesundheit?

Whether a microbiome test can help with gut health is not clearly supported by current evidence. These tests analyze the composition of gut bacteria and are often marketed with promises of personalized dietary advice to improve gut health. However, the scientific evidence is weak: there are no standardized, clinically validated reference ranges for a 'healthy' microbiome, and results vary significantly between different test providers. Moreover, randomized controlled trials demonstrating that diets based on such tests actually improve gut health or reduce disease risk are lacking. Most available data come from observational studies or mechanistic work, showing associations but not causality. A microbiome test may serve as an exploratory tool, but it should not be the sole basis for medical decisions or dietary changes. For specific gut complaints, a medical evaluation (e.g., stool analysis, endoscopy) is far more informative. Marketing claims that promise direct benefits should be viewed critically.
