What role does VKORC1 play in Darmgesundheit?

VKORC1 encodes vitamin K epoxide reductase, a key enzyme for vitamin K recycling. Vitamin K is crucial for blood clotting and bone metabolism, but also for certain vitamin K-dependent proteins in the gut, such as osteocalcin and matrix Gla protein. Some studies suggest a potential role of these proteins in gut barrier function and inflammation regulation. However, direct evidence linking VKORC1 variants to human gut health is insufficient. Most associations come from pharmacogenetic studies (e.g., warfarin dosing) or animal experiments. Without specific GWAS or clinical data on gut parameters, the evidence remains weak. Therefore, VKORC1 should not be considered a central factor for gut health, but rather part of vitamin K metabolism that may indirectly influence systemic effects.
