Green leafy vegetables, such as kale, spinach, and broccoli, are excellent sources of vitamin K. These vegetables are rich in vitamin K1 (phylloquinone), which plays a crucial role in blood clotting and bone health. Other sources of vitamin K1 include Brussels sprouts, asparagus, parsley, and certain vegetable oils like soybean oil and canola oil. Vitamin K2 (menaquinones) can be found in fermented foods like natto and cheese, as well as in liver, eggs, and meat. Including a variety of these vitamin K-rich foods in your diet can help ensure an adequate intake of vitamin K and support various physiological functions in the body.
