Watch Out For Vitamin K

I have a history of blood clots in my lungs. Is it true that I should not drink green tea since it contains a lot of vitamin K?

Andrew Weil, M.D. | November 27, 2002

Since you have a history of blood clots, I assume that you are taking Coumadin or another blood-thinning drug. If so, you do have to be aware of your intake of vitamin K, an essential nutrient necessary for blood clotting that occurs in many vegetables. Vitamin K antagonizes the action of Coumadin. People taking anticoagulants should maintain a consistent intake of vitamin K so that their drug dosage does not have to be adjusted and readjusted. For instance, if you eat lots of vegetables, make sure that the total amount you eat each day is relatively constant and be sure to discuss any major change in your diet with your physician.

It is true that dried green tea leaves have a very high concentration of vitamin K, but a cup of brewed green tea provides only a small amount, 0.03 mcg per 3.5 fluid ounces . In fact, research published in the Journal of the American Dietetic Association in 1995 showed that tea is not a significant dietary source of vitamin K and, as you know, green tea provides lots of other health benefits. The only beverages you should avoid while on blood-thinners are alcoholic drinks of all types since alcohol can affect your response to these drugs.

It has been reported that these antiplatelet effects are mediated by mechanisms involving inhibition of formation, release, and/or actions of platelet-activating/aggregating endogenous mediators by constituent compounds present in the different herbal products reviewed, as depicted in Fig. .

    You also need to avoid activities and sports that could cause injury. Swimming and walking are safe activities. If you would like to start a new activity that will increase the amount of exercise you get every day, talk to your doctor.

    Tell others.Keep a current list of all the medicines you take. Ask your doctor about whether you should wear a medical alert bracelet or necklace. If you are badly injured and unable to speak, the bracelet lets health care workers know that you are taking a blood thinner.

    Herbs With Anticoagulant Properties

    Herbal supplements reported to have anticoagulant activities have been shown to contain coumarins, together with other constituents. Coumarins exist as natural as well as synthetic compounds, and the widely used prescription anticoagulant, warfarin, is a synthetic derivative. These compounds are blockers of the action of vitamin K, and, as such, interfere with the synthesis of clotting factors and clot formation .2). Below are described the commonly used herbal supplements with reported anticoagulant activities.


    Chamomile is commonly used for its claimed benefits as an antispasmodic and a sedative . Being classified as a dietary supplement, it is marketed in the forms of capsules, fluid extracts, and tea bags. Chamomile consists of multiple compounds, including coumarins, heniarin, flavonoids, farnesol, nerolidol, germacranolide, and various glycosides . Despite the presence of coumarins, the effect of chamomile per se on the coagulation process has not been investigated. However, an isolated case of enhanced bleeding in a patient taking warfarin with chamomile has not been reported . Thus, the effect of the herb alone on hemostasis is not clear. However, until more definite information is available, it is advisable to be vigilant of its potential effect on blood clotting.
