Vitamin K is a fat-soluble vitamin best known for its essential role in blood clotting. It’s a nutrient that many parts of the body use, including the brain, heart, liver, bones, and pancreas. Most people get this nutrient through their food, but some also take it in through nutritional supplements.
What Is the Role of Vitamin K in Blood Clotting?
Vitamin K helps prevent excessive bleeding by supporting the production of proteins necessary for blood clotting. The protein prothrombin, which is synthesized by the liver, helps in blood coagulation and bone metabolism. It is highly dependent on vitamin K.
What Are the Other Benefits of Vitamin K?
Not only is vitamin K known for its integral role in blood clotting, but it also helps maintain healthy functions in other organs. The benefits of this nutrient include:
- Promoting Healthy Cognition and Memory: Adequate levels of vitamin K help improve episodic memory in many older adults. This type of memory is necessary for remembering specific experiences and events in the past.
- Strengthening Bones: The vitamin K-dependent protein osteocalcin helps improve bone metabolism and density, making them stronger and more resistant to fractures.
- Maintaining Heart Health: The nutrient prevents mineral buildup in the arteries, which can help in maintaining optimal heart health. It also assists in regulating blood pressure and mitigating the risks of heart disease.
What Happens If You Don’t Get Enough Vitamin K?
Most people get vitamin K through their diets, and the bacteria in the large intestines can also synthesize this nutrient. As a result, deficiency is rare in adults. However, people who take medications that interfere with vitamin K absorption, are heavy alcohol drinkers, or have digestive diseases such as Crohn’s or celiac disease are vulnerable to having low levels of the nutrient. Doctors may advise them to take nutritional supplements.
Vitamin K deficiency can lead to the inability to form blood clots, which increases the risk of uncontrolled bleeding. Newborns are typically prone to having low levels of this nutrient, so doctors often administer injections to provide the babies with a boost.
What Are Good Sources of Vitamin K?
There are two main types of vitamin K: phylloquinone (K1) and menaquinone (K2). Phylloquinone can be found in green leafy vegetables, canola oil, soybeans, and fortified shakes. Menaquinone, on the other hand, is synthesized by the liver. It also exists in small amounts in meat, eggs, and cheese.
Are There Any Risks Involved?
The body readily discards excess vitamin K through urine, so it typically does not pose any risks in the human body. However, some medications should not be taken with this nutrient. It’s best to consult healthcare professionals before taking any nutritional supplements for vitamin K.
Boost Your Immunity with Nutritional Supplements
Vitamin K is a fat-soluble nutrient that plays a vital role in blood clotting and preventing excessive bleeding. It also promotes healthy bodily functions, particularly in memory, bone strength, and heart health. While vitamin K exists in many foods and deficiency is rare, many people can benefit from nutritional supplements that provide them with their daily needs.
