Vitamin K is a fat-soluble vitamin that is naturally present in some foods and is available as a dietary supplement. Here are some foods that are high in vitamin K:

• Green leafy vegetables: These include collard greens, kale, spinach, broccoli, Brussels sprouts, cabbage, and lettuces.

• Oils: Soybean and canola oil are good sources of vitamin K.

• Meal replacement shakes: Some fortified meal replacement shakes contain vitamin K.

• Fermented soybeans: Natto, a Japanese dish made from fermented soybeans, is one of the best sources of vitamin K2.

• Meat and dairy products: Vitamin K2 is more common in animal products, dairy, and fermented foods.

It is important to note that vitamin K works against warfarin, a medication used to prevent blood clots. If you are taking warfarin, it is important to eat about the same amount of foods high in vitamin K each day and to check with your healthcare provider before making any big changes in your diet.
