Vitamin K is a fat soluble vitamin that’s essential for normal blood clotting and wound healing. There is also evidence that vitamin K is important for good bone strength.
Since it’s a fat soluble vitamin, the body can store any excess vitamin K in it’s fat stores, so you don’t have to eat vitamin K rich foods every day. Although vitamin K rich foods should form part of a healthy diet and it will do no harm if you do eat these foods on a daily basis.
Dark, leafy greens such as spinach, kale and broccoli are good natural sources of vitamin K, as are unprocessed cereal grains. A popular Japanese dish called natto, which is made from fermented soybeans, is also a good source of vitamin K.
