Can NutriCare | INFINITY DNA-Test help with gut health?

The NutriCare | INFINITY DNA-Test is a genetic test analyzing 140+ gene variants related to metabolism. It does not directly measure gut health, as that requires a stool sample (microbiome analysis). The DNA test may offer clues about genetic predispositions, e.g., for lactose intolerance or gluten sensitivity, but evidence for precise diet-gene interactions is weak (mostly marketing). Gut health is primarily driven by microbiome composition, fiber intake, inflammation, and lifestyle – none of which this test assesses. 'Leaky gut' cannot be diagnosed with any validated stool biomarker. Bottom line: the test can provide general inspiration but should not replace medical advice or a dedicated microbiome test. Evidence grade: marketing/unclear.
