Can Nährstoffcheck help with gut health?

MyBody-X's Nährstoffcheck measures vitamins, minerals, and trace elements in blood (e.g., vitamin D, B12, zinc, selenium). It is not a direct test of gut health – separate microbiome tests exist for that. However, nutrient deficiencies can indicate impaired gut function: reduced absorption (e.g., in celiac disease, Crohn's, or IBS) often leads to low levels of iron, B12, folate, or fat-soluble vitamins. Thus, the check provides indirect clues but does not replace stool analysis or endoscopy. The evidence for its benefit in gut health is mechanistic: the link between nutrient deficiency and gut pathology is well-established, but the test alone cannot diagnose gut disease. Caution against overinterpretation: normal nutrient levels do not rule out gut problems. For persistent symptoms (bloating, diarrhea, abdominal pain), a doctor's visit with targeted diagnostics (e.g., lactose intolerance test, calprotectin, stool culture) is advisable. The Nährstoffcheck can serve as supplementary orientation, not a standalone tool.
