Vitamin K is the vitamin that helps in blood clotting. It plays an essential role in synthesizing proteins required for blood coagulation, which prevents excessive bleeding from injuries. Vitamin K exists in two main forms: K1, found in green leafy vegetables like spinach, and K2, found in animal products and fermented foods. Adequate intake of this vitamin is crucial for maintaining healthy blood levels and overall bone health. It is particularly important for individuals who have undergone certain types of surgery or those on anticoagulant medications.
