Can VKORC1 help with fatigue?

There is no scientific evidence that VKORC1 can help with fatigue. VKORC1 encodes an enzyme involved in vitamin K metabolism and is primarily relevant for warfarin dosing. No validated studies link VKORC1 variants to general fatigue or tiredness. Fatigue has many causes—sleep deprivation, iron deficiency, thyroid disorders, and others. A consumer DNA test for VKORC1 does not provide actionable information for fatigue. Claims that it does are likely marketing-driven rather than evidence-based. Anyone experiencing persistent fatigue should seek medical evaluation rather than rely on isolated genetic markers.
