Which food is a significant source of vitamin K?

Leafy greens are recognized as a significant source of vitamin K, primarily because they contain high concentrations of phylloquinone (vitamin K1), which is essential for various bodily functions, particularly in blood clotting and bone health. Foods such as spinach, kale, collard greens, and Swiss chard are some of the most effective sources of this vitamin, making them important additions to a balanced diet. Vitamin K plays a crucial role in the synthesis of proteins required for blood coagulation and the metabolism of calcium in bone and other tissues. While other food groups might contain some vitamin K, leafy greens are by far the most robust and reliable source, highlighting their importance in promoting optimal health in relation to this micronutrient.
