High Vitamin K: what it means
A Vitamin K result above the normal range is considered high. Here is what a raised Vitamin K can point to, and when it is worth discussing with a doctor.
Reference range: ~0.5–3.0 nmol/L; needed for blood clotting — deficiency is usually detected through a raised INR rather than by measuring the vitamin directly

- Supplementation — the usual reason; not generally harmful.
- A high level is rarely the clinical concern — the important direction is deficiency and its effect on clotting.
When to discuss with a doctor
Vitamin K deficiency is usually recognised through its effect — a prolonged prothrombin time or raised INR with bruising or bleeding — rather than by measuring the vitamin, which is not a routine test. It is worth considering in someone with fat malabsorption or liver disease who has unexplained bleeding or a raised INR, where giving vitamin K can correct it. In an emergency, a dangerously high INR (whether from warfarin or liver disease) with bleeding is treated urgently, sometimes with vitamin K. Newborns receive vitamin K routinely to prevent bleeding. Mediora.AI shows the INR alongside liver markers so a vitamin K-related clotting problem is visible in context; the interpretation and treatment belong with your doctor.
