Vitamin K deficiency is rare, but good sources of Vitamin K-1 include most leafy green vegetables, like spinach, broccoli, parsley, kale and brussels sprouts. Avocados and kiwifruit also contain high amounts of vitamin K. Vitamin K-2 can be found in meat, eggs, and dairy products.
Some vegetables providing large amounts of Vitamin K are kale, spinach, turnip greens, beet greens, collards, brussel sprouts, and mustard greens. Anyone taking blood thinners such as Coumadin should be careful because Vitamin K contains a natural blood-clotting agent. Consult your doctor if this applies to you.
