Functions Of Vitamin K In The Human Body
Vitamin K is a fat-soluble vitamin that is essential for blood clotting and bone health. It is a group of compounds that include vitamin K1 and vitamin K2. Vitamin K1 is found in plants, while vitamin K2 is produced by bacteria in the gut and is also found in some animal products.
Role in Blood Clotting
Vitamin K plays a crucial role in the blood clotting process. It helps in the production of proteins called clotting factors that are responsible for stopping bleeding when we get injured. Without vitamin K, the blood would not be able to clot properly, leading to excessive bleeding.
People who have a deficiency of vitamin K are more prone to bleeding and bruising. This is especially true in newborns who are born with low levels of vitamin K and are at risk of bleeding in the brain.
However, people who are on blood-thinning medications such as warfarin should be careful about consuming too much vitamin K as it can interfere with the medication and increase the risk of bleeding.
Role in Bone Health
Vitamin K also plays an important role in maintaining bone health. It helps in the production of a protein called osteocalcin, which is responsible for binding calcium to the bones. This process helps to keep the bones strong and healthy.
Studies have shown that people who have higher levels of vitamin K in their diet have a lower risk of fractures and osteoporosis. This is especially true in postmenopausal women who are at a higher risk of developing osteoporosis.
Sources of Vitamin K
Vitamin K1 is found in green leafy vegetables such as kale, spinach, and broccoli, while vitamin K2 is found in fermented foods such as cheese and natto.
Other sources of vitamin K include liver, egg yolks, and butter.
Conclusion
Vitamin K plays an important role in blood clotting and bone health. It is essential to consume enough vitamin K in the diet to prevent deficiencies and maintain good health. However, people who are on blood-thinning medications should be careful about their vitamin K intake. A balanced diet that includes a variety of fruits, vegetables, and animal products can provide enough vitamin K for the body.
