Vitamin K3, or Menadione, is a synthetic (lab-made) form of Vitamin K. Unlike natural K1 from greens or K2 from fermented foods, it's not found in what you eat it's created for specific medical needs. Your body can turn it into active Vitamin K, but it's only used in controlled settings due to risks. 2025 guidelines stress it's not for everyday supplements or diets, just emergencies Healthline, 2025. Here's a practical look at its medical roles.

Explanation of Medical Uses

• Treating Severe Deficiency
  Used when natural Vitamin K forms aren't enough or can't be absorbed. For example, newborns with hemorrhagic disease (HDN) may get K3 to stop life-threatening bleeding. It's a quick fix in hospitals where other options fail Vinmec, 2025.

• Emergency Clotting Support
  Given to people with absorption issues, like cystic fibrosis or celiac disease, who can't get enough from food. It helps restore clotting fast in urgent cases.

• Addressing Bleeding Disorders
  In hospitals, K3 rapidly boosts clotting for severe bleeding from trauma, surgery, or other crises. It's administered as shots or pills under doctor watch.

Cautions and Risks

Because it's synthetic, K3 skips some body checks, raising toxicity chances like liver damage or anemia (especially in folks with G6PD deficiency). 2025 updates warn it's harmful in high doses and banned in human supplements in many places Healthline, 2025. Only use under pro supervision stick to natural K sources for daily health.

Key Takeaway
