medications, the body regulates clotting factors efficiently. Excess vitamin K does not typically lead to harmful over-clotting because the system reaches a natural saturation point, as noted in reviews from institutions studying coagulation.
However, for seniors on anticoagulants, large or inconsistent amounts of vitamin K (from supplements or sudden diet changes) can reduce the medication’s effectiveness, potentially allowing clots to form more easily. This is why doctors often advise keeping vitamin K intake steady rather than eliminating it. Observational data and clinical guidelines stress monitoring rather than blanket avoidance.
