Food Sources of Vitamin K
Information About Vitamin K
- Vitamin K is a fat soluble vitamin. You need some vitamin K every day for good health.
- Vitamin K helps your blood to clot when you are bleeding. People who take warfarin (Coumadin®) should aim for about the same amount of vitamin K each day. Warfarin is a blood thinning medication.
- Vitamin K also helps to build strong bones.
- There are two forms of vitamin K: vitamin K1 and vitamin K2.
- Vitamin K1 is mostly found in plants and is our main dietary source of vitamin K.
- Vitamin K2 is found in fermented foods and in some meats and cheeses. It is also made by our body from vitamin K1 in the food we eat.
