Can you drink v8 juice while taking warfarin?

The concern when taking warfarin (coumadin) is the amount of vitamin K ingested. Vitamin K can reduce the anti-clotting action.

Generally, the highest amounts of vitamin K are found in green leafy vegetables. There is a moderate amount in V8, and even less in Tomato Juice. An occasional small glass of V8 is probably not harmful, but sticking to regular tomato juice in reasonable quantities is even safer. See the Related Links below the ads.
