Evidence check: Cardio Risk Check | Herz-Kreislauf Risiko-Test in the context of gut health

The 'Cardio Risk Check' in the context of gut health is an area of active research but lacks sufficient validation for consumer tests. There is emerging evidence that the gut microbiome can influence cardiovascular risk through metabolites like TMAO, short-chain fatty acids, and bile acids. However, no prospective studies have established a direct causal link between a single microbiome test and hard cardiovascular endpoints. Most commercial offerings rely on associations rather than clinical validation. Such a test cannot replace established risk factors like lipids, blood pressure, smoking, or diabetes. The evidence is best classified as marketing or unclear. Caveat: do not use this test for medical decisions; consult a physician for comprehensive cardiovascular risk assessment.
