What role does Nährstoffcheck play in gut health?

A nutrient check (e.g., MyBody-X Nährstoffmangel-Test) can play an indirect role in gut health by identifying deficiencies in micronutrients essential for gut barrier function, immune modulation, and mucosal integrity – such as vitamin D, zinc, iron, and B vitamins. Deficiencies in these nutrients may alter the gut microbiota composition and promote low‑grade inflammation. However, the test does not directly assess the microbiome or intestinal permeability. Evidence for routine nutrient screening in healthy individuals is moderate; it provides a snapshot of current status, not a comprehensive gut health evaluation. For gastrointestinal symptoms, medical consultation is advised. The test can be a useful adjunct but should not replace stool analysis or endoscopy. Evidence grade: practice (clinical routine) – links between nutrient status and gut health are well established, but the specific test as a standalone tool lacks robust validation.
