About Coumadin® (warfarin)

The main dietary concern of taking warfarin (common brand name: Coumadin) has to do with the amount of vitamin K in your diet. Vitamin K changes the way warfarin affects the blood. When you eat foods that are high in vitamin K, you can decrease the effect of warfarin. Likewise, eating less vitamin K can increase the effect of the medication.

PeppersThe key is to try to eat a similar amount of foods that contain vitamin K each day. Don’t make any major changes to your diet without speaking with your doctor. If you want to lose weight, eat a lower fat diet or become a vegetarian, your doctor would want to know about these changes to help manage your warfarin.

Leafy green vegetables tend to contain higher amounts of vitamin K and one rule of thumb is to suspect that green veggies, cabbages and lettuces are high in Vitamin K. Also certain legumes like peanuts and peas might cause problems. Certain vegetable oils have high amounts of vitamin K.

Foods that are low in vitamin K include roots, bulbs, tubers, some fruits and fruit juices. Cereals, grains and other milled products are also low in vitamin K.

Wine glassKeep in mind that the amount of foods you eat with vitamin K add up. So if you eat more foods that contain medium amounts of vitamin K in a particular day, your vitamin K intake will be high for that day.

What about alcohol?

You should avoid drinking alcohol while taking warfarin because alcohol can change the way your body responds to the medicine. Talk with your doctor about this. He or she may tell you that it’s fine to drink alcohol but may want you to have a similar amount of alcohol each day so that your blood levels of warfarin remain stable.

How well is Vitamin K absorbed?
Recent studies suggest that the average American diet does not contain enough Vitamin K, which contributes to proper blood coagulation. Since phylloquinone, the primary source of Vitamin K in plants and plant oils, is soluble in fat, researchers have long assumed that phylloquinone would be more easily absorbed from an oil than from a vegetable source. Further, indicators of Vitamin K status in the blood or urine are different in younger adults than in older adults. More....

American Ginseng Can Reduce the Effects of Warfarin
Ginseng is felt by some to help with energy and vitality, especially during stress. Some feel it can improve memory and "brain power." There has been little solid evidence to support this, however. In a paper published in The Annals of Internal Medicine (2004; 141:23-27) Dr. Yuan and his study team had twenty patients take warfarin. In the first week the medication was given and the INR checked. In the second week, 12 of the participants began also taking American ginseng, while 8 began taking a placebo. More....
