The vitamin essential for blood clotting is Vitamin K. This fat-soluble vitamin plays a crucial role in the synthesis of proteins necessary for blood coagulation, helping to prevent excessive bleeding when injuries occur. Vitamin K is present in two main forms: K1 (phylloquinone), which is found in green leafy vegetables, and K2 (menaquinone), which is found in fermented foods and animal products. A deficiency in Vitamin K can lead to serious health issues, including an increased risk of bleeding disorders. Ensuring adequate intake through diet or supplements is vital for maintaining overall health and wellness.
