Can CRP Entzündung help with gut health?

CRP (C-reactive protein) is a general inflammation marker produced by the liver in response to systemic inflammation. It is not specific to gut health. An elevated CRP level can indicate inflammation somewhere in the body, but it does not reveal the cause or location. Gut health involves microbiome composition, barrier function, digestion, and immune regulation – aspects CRP cannot capture. No validated studies show that CRP testing directly improves gut health. Some companies market CRP as part of 'leaky gut' or gut health panels, but the evidence is weak and not endorsed by medical societies. For meaningful gut health assessment, more specific markers like fecal calprotectin (for inflammatory bowel disease) or symptom-based evaluation are appropriate. CRP may serve as a rough screening parameter but does not replace proper diagnostics. Caveat: A normal CRP does not rule out gut issues; an elevated level requires medical follow-up.
