Health Benefits of Vitamin K Explained
Vitamin K is a highly beneficial nutrient for the body. It plays a vital role in blood clotting, regulating calcium levels, and bone metabolism.
Hence, apart from the benefits of vitamin k, the article will also look at the uses and sources of vitamin K. Check it out below!
What Are the Health Benefits of Vitamin K?
Listed below are the different benefits of vitamin K!
1. Production of Prothrombin
The body uses vitamin K in the production of prothrombin. Prothrombin is a protein that is required for blood clotting and bone metabolism. Therefore, low levels of vitamin K eventually lead to uncontrolled bleeding as there is poor blood clotting.
2. Develop Healthy Bones
While there is insufficient research to prove that vitamin K is essential for bone health, some studies have indicated it to be the case. Hence, vitamin K may help with the following:
- Maintain Strong Bones
- Improve Bone Density
- Reduced Risk of Fractures
3. Better Cognitive Health in Older Adults
According to a study on "Vitamin K status and cognitive function in healthy older adults", vitamin K was linked with improved episodic memory in older adults. Therefore, vitamin K is required for improved memory in people above the age of 70.
4. Prevent Mineralisation
Mineralisation occurs when minerals build up in arteries. Vitamin K may help prevent mineralisation. As a result, the heart can pump blood through arteries free of deposited minerals, that too more efficiently.
5. Development of Bone Tissue
Vitamin K is also necessary for the development of bone tissue. Consequently, it is needed to produce protein osteocalcin required for healthy bone tissue.
How to Figure out if You Have Vitamin K Deficiency?
Vitamin K deficiency is rare. However, to figure out if you have a deficiency, look out for the signs of it. Listed below are the signs of vitamin K deficiency:
- Increased Time for Blood to Clot (known as prothrombin time)
- Bleeding
