Vitamin K is widely available in both plant- and animal-based foods. You can get enough vitamin K just by having one serving of green leafy vegetables a day. You do not need to supplement to get enough vitamin K in your diet.

• Vitamin K1, also called phylloquinone, comes from plant sources like leafy greens. Some examples of food sources include spinach, broccoli, kale, Bok Choy, Natto (Fermented soybeans) and sauerkraut.
• Vitamin K2, the menaquinones, comes from animal products and fermented foods. K2 is also the form of Vitamin K that is made by the healthy bacteria in your intestines. Some examples of food sources include liver, eggs, chicken and cheese like cheddar, Munster and camembert.
