Only if on coumadin (warfarin): Vitamin k interferes with the actions of coumadin, (warfarin) but that it a big reason i don't like coumadin, (warfarin) as people on it suffer from lack of vit k. It makes more sense to take a steady amount of k-rich foods & adjust Coumadin (warfarin) dose accordingly. Some say to avoid k if you have g-6-pd deficiency, are on dialysis or have cirrhosis, but foods high in k should be fine; they just should not supplement with it.

The danger is that wide variations in dark green vegetables (sources of Vit K) will result in wide swings in the effects of coumadin. Best to work with your doctor and keep a fixed amount of greens in your daily diet. The benefits of eating these foods are enormous.
