Juicing and the anticoagulant Coumadin ( Warfarin)



heart health, heart,coumadin,warfarin,juicing

I received a question asking if people who take Coumadin (also known as Warfarin) can juice and secondly which juices are suitable to use alongside this anti coagulant medication It is a good question as this blood-thinning drug is widely used, so I thought it would be important to cover this topic. Please be aware you do need to consult with your practitioner as well.

If you are taking Coumadin, your practitioner will have already informed you of the foods and drinks to avoid or cut down on. The foods and beverages which are high in vitamin K and drinks such as alcohol and cranberry juice do need to be used with great care. Unfortunately those important leafy green vegetables, juices, green tea,some vegetable oils and others  are on the be aware list since they are all sources of vitamin K and will interfer with the effectiveness of Coumadin / Warfarin .

What’s the issue with vitamin K?

heart health, heart,coumadin,warfarin,juicingThe number one functions of vitamin K is to assist the blood to clot. This is a natural healthy process and without it ,we would bleed to death, particularly  if we cut our selves badly. Anyone with thicker blood levels,which has the potential to be life threatening will be prescribed a medication like Coumadin. Thicker blood levels can lead to possible strokes or a heart attack.

Coumadin is a blood-thinning medication.It has the very opposite effect to vitamin K within the body. It is very important to have sources of vitamin K in the diet because it is an essential vitamin and those taking Coumadin medications must take care to limit their intake of Vitamin K so it doesn’t counter effect the blood thinning medication

Which vegetables have  high in Vitamin K levels ?

Drinking vegetable juices every day can be highly beneficial and play a vital role for those with cardiovascular disease. Fresh organic juices can help lower blood pressure, detoxify the blood, promote a healthier cholesterol profile and help slow down or reverse the progression of atherosclerosis. So,yes, for those using Coumadin, it is a great idea to drink fresh juices everyday, as long as the juice is made from vegetables low in vitamin K.I have listed the most important vegetable  to avoid for you:
• chinese broccoli
• cabbage

These vegetables are low in Vitamin K

This is your list of ‘Coumadin / Warfarin friendly’ vegetables which contain the smallest amounts of vitamin K.

• beetroot
• carrots sweet potatoes
• cucumber (without the skin)
• green pepper
• lettuce
• celery
• iceberg lettuce
• romaine lettuce
• red / yellow capsicum/ peppers
I particularly recommend celery as it is full of antioxidants called phthalides. Studies have shown celery juice has a relaxant effect on the muscles of the major arteries. This way, the arteries are able to expand more when pumping blood, in turn, lowering blood pressure.

Vitamin K and Fruits

Vit K, fruit,antioxidantsLuckily no fruit has high levels of vitamin K! They all have low levels with the exception of pomegranates and green apples (red are low) which contain small to moderate amounts, but, they are not high and safe. It is recommended apples be juiced with their skins on as numerous studies point to apple juice lowering the “LDL” bad cholesterol levels as well as lowering blood pressure. While juice made from peeled apples also helps, peels and apples juiced together are by far healthier for you because of the mineral and vitamin content held in the skins.

What about Green Tea , Alcohol and Cranberry Juice  ……

Alcohol and Cranberry juice must be reduced to a very minimal amount or cut-out completely from the diet all together. They all have strong blood-thinning effects. Taken in conjunction Coumadin, this may over thin the blood too much. Green tea, while wonderfully healthy, sadly is a beverage high in vitamin K! This is a pity as green tea is full of wonderful antioxidants and hugely beneficial for heart health!

I hope I have given you some inspirational ideas for your juices and also so you can see,you don’t have to stop juicing! Simply choose the right ingredients for you if you are on blood thinning medications such as Coumadin / Warfarin.

here’s to your health,
