A 32-year-old male asked:

in which diseases/disorders is it not a good idea to eat foods high in vitamin k?

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.

It sounds like: You are buying it just to buy it...Maybe something you read? Vit k is needed for proper clotting and is not a supplement you need unless you have clotting issues and a hematologist has recommended it. Dark leafy greens contain vitamin k and it should be enough for your health. It is best to get our vitamins form foods first. Supplement for specific deficiencies.

No: Most do not require extra vit k. Vit k may be beneficial for a select group of patients - those with intravenous feedings, those with malabsorption and those on long term antibiotics. Sometime pts with difficult to control INR while on Coumadin (warfarin) are given low dose vit k to help regularize their numbers.
