| What does vitamin K do to the body? |
| 2024-11-11 |
| Vitamin K is a fat-soluble vitamin that is essential for various bodily functions, particularly:
Blood Clotting: Vitamin K is best known for its critical role in blood coagulation (clotting). It is necessary for the synthesis of several proteins involved in blood clotting, which helps prevent excessive bleeding when injuries occur. Bone Health: Vitamin K contributes to bone metabolism by helping the body utilize calcium to build and maintain strong bones. It supports the activity of osteocalcin, a protein that binds calcium to bones, thus enhancing bone mineral density and reducing the risk of fractures. Heart Health: Vitamin K plays a role in preventing the calcification of blood vessels and arteries. It activates proteins that help prevent calcium buildup in the arterial walls, which supports cardiovascular health by keeping blood vessels flexible. Types of Vitamin K: Vitamin K1 (phylloquinone): Found mainly in leafy green vegetables like kale, spinach, and broccoli. Vitamin K2 (menaquinone): Found in fermented foods and animal products such as cheese, eggs, and natto (fermented soybeans). K2 is believed to be more effective for bone and heart health. A deficiency in vitamin K can lead to issues such as easy bruising, excessive bleeding, and, over time, weakened bones and an increased risk of cardiovascular problems. |
