When it comes to a nutritious diet, paying attention to the vitamins and minerals our bodies need is essential. One such vital nutrient is Vitamin K, a fat-soluble vitamin is critical in blood clotting and bone health. While Vitamin K deficiency is rare, ensuring an adequate intake of this essential nutrient can help promote optimal health.
Fortunately, obtaining Vitamin K from your diet is relatively easy, as numerous foods are excellent sources of this vital vitamin. In this article, we will explore 20 foods that are rich in vitamin K sources.
Types of Vitamin K
Vitamin K exists in the following two forms.
It is the principal type of vitamin K abundantly present in green leafy vegetables. These include collard greens, kale, and spinach. As a plant-based source, phylloquinone supports blood clotting and bone health. 
Menaquinones are the second type of vitamin K sourced from animal foods and fermented products. They contribute to the overall vitamin K intake, with their potential implications for cardiovascular health. 
What are Vitamin K benefits?
Here are key areas where vitamin K demonstrates notable benefits.
1. Blood clotting
Vitamin K is necessary for protein synthesis in blood clotting. Adequate vitamin K levels are fundamental for maintaining proper blood clotting function. 
2. Bone health
Vitamin K contributes significantly to bone health by regulating calcium within the skeletal system. Ensuring sufficient vitamin K intake can enhance bone density and reduce the risk of fractures. 
3. Heart disease
Research indicates a potential link between vitamin K and cardiovascular health. It may play a role in preventing arterial calcification to promote cardiovascular health.
