What is Vitamin K?


Vitamin K refers to a group of fat-soluble vitamins that play a role in blood clotting, bone metabolism, and regulating blood calcium levels.

The body needs vitamin K to produce Prothrombin, a protein and clotting factor that is important in blood clotting and bone metabolism. People who use blood-thinning medications, such as Warfarin, or Coumadin, should not start consuming additional vitamin K without first asking a doctor.

Vitamin K is made by the bacteria in the lower intestinal tract, but it is also found in the following foods:

- Green leafy vegetables
- Broccoli, cauliflower, and cabbage
- Fish, liver, meat, eggs, and cereals (contain smaller amounts)
