Vitamin K plays a vital role in human health, primarily in blood clotting and maintaining bone health. It is essential for the synthesis of proteins that mediate coagulation, preventing excessive bleeding. Additionally, vitamin K contributes to bone metabolism, helping to bind calcium within bones, which may lower the risk of fractures. Adequate levels of vitamin K can therefore help support overall skeletal integrity and cardiovascular health. It is found in green leafy vegetables, dairy, and fermented foods, making dietary sources crucial for maintaining its levels.
