Vitamin K is a fat-soluble vitamin that plays an essential role in blood clotting and bone health. There are two main forms of vitamin K: vitamin K1 (phylloquinone) and vitamin K2 (menaquinones). Vitamin K1 is found in leafy green vegetables, while vitamin K2 is found in animal products and fermented foods. Some fruits are also rich in vitamin K1. It is important to get enough vitamin K in your diet because a deficiency can lead to a bleeding disorder called vitamin K deficiency bleeding (VKDB), which can be particularly dangerous in new-borns. Additionally, low intake of vitamin K is associated with an increased risk of bone fractures.

It is worth mentioning that if you take blood-thinning medications or have any other medical conditions that make you more susceptible to bleeding, you should talk to your doctor about how much vitamin K you should consume, as too much vitamin K can interact with these medications and affect their effectiveness.
