Vitamin K and Wheatgrass

Vitamin k and wheatgrass:

All About Vitamin K:

Vitamin K is a fat-soluble vitamin, which means your body stores excess amounts in the liver and in fatty tissue.

 The vitamin's main role is to support proper blood coagulation. 

Bacteria in your intestines make a small amount of vitamin K, and you also get it form your diet.

Vitamin K in Wheatgrass:

The daily value for vitamin K is 80 micrograms.

 A small 4-gram serving of wheatgrass contains 35 micrograms of vitamin K, which is 44 percent of the daily value. 

This is a moderate amount, but some powdered wheatgrass juice supplements can contain as much as 160 percent of the DV for vitamin K.

Vitamin K and Warfarin:

People who take warfarin need to keep their vitamin K intakes as consistent as they can. 

Suddenly increasing your vitamin K intake by drinking wheatgrass juice can decrease the effectiveness of warfarin and increase your risk of developing a blood clot. 

The National Institutes of Health advises people who take warfarin to limit their intake of of foods that contain moderate amounts of vitamin K -- between 60 percent and 199 percent of the DV -- to three servings per day. Wheatgrass is considered a supplement and not a food, however.

 NIH cautions those who take warfarin to avoid supplements that list vitamin K on the label unless they have a doctor's permission.
