Vitamin K

Vitamin K is a fat-soluble vitamin that plays an important role in maintaining human health. It is involved in the blood clotting process and helps maintain bone health.

There are two main forms of vitamin K: phytomenadione, which is a plant-based vitamin, and menaquinone, which is an animal-based vitamin. Phytomenadione is commonly found in green leafy vegetables such as spinach, kale, broccoli and arugula, as well as vegetable oils. Menaquinone, on the other hand, is found in foods such as meat, eggs, and dairy products.

One of the main functions of vitamin K is its participation in the synthesis of blood clotting factors, especially prothrombin. If there is a lack of vitamin K, prothrombin levels may decrease, resulting in increased clotting time and an increased risk of bleeding. However, vitamin K deficiency in the body is rare because it is synthesized by bacteria in the colon.

Additionally, vitamin K plays an important role in bone health. It helps retain calcium in bones and prevent bone breakdown. A lack of vitamin K can lead to osteoporosis and an increased risk of bone fractures.

The recommended daily intake of vitamin K for adults is about 90 micrograms. Pregnant women and nursing mothers are advised to increase their vitamin K intake.

Conclusions: Vitamin K plays an important role in maintaining human health. It is involved in the blood clotting process and helps maintain bone health. A lack of vitamin K can lead to increased clotting time and osteoporosis. Therefore, it is important to include foods that contain vitamin K in your diet, such as green vegetables, meat, eggs and dairy products.



Vitamin K is an essential fat-soluble element that is necessary for the normal functioning of the entire body. Many people know about its important role in the formation of clotting factors, but this is not the only property of vitamin K. Moreover, vitamin substances of this type help improve calcium absorption, ensure healthy bones and are even involved in body weight control. What are the functions of vitamin K, how does its deficiency manifest itself in the human body, and what kind of test should you take if you think this mineral is of greatest value in preventive medicine?

Vitamins K are found in foods of plant and animal origin. Bacteria in the human large intestine pump up vitamin K from the form phytomenadione. After which this element enters the blood, from where it goes to the bone marrow and liver for the production of coagulation factors. Vitamin K2 is synthesized in the small intestine, mainly by epithelial cells, and is secreted along with bile into the large intestine. The main source of the vitamin is green plant products: green leafy vegetables, garden herbs and spinach. Eating asparagus, sweet peppers, Brussels sprouts and broccoli also guarantees a significant amount of vitamin K in our body. Small amounts of vitamin K can be found in cereals, nuts, eggs, butter and fatty fish. Animal products such as dairy, poultry and meat are richer in the mineral than plant sources. Animals obtain the menaquin form of vitamin K from food products - milk, cottage cheese, butter, fish oil and eggs. Bacterial sources are considered more nutritious and vital. Vitamin K is synthesized by the intestinal microflora of animals, birds, ticks and ants. Among animal products, it is very important, since it is not found in fruits, vegetables, nuts and grains, as well as in vegetable oils and dairy products.

The functions of vitamin K are many and varied. First of all, it plays a large role in bone metabolism, controlling calcium levels and reducing the risk of bone tumors. Additionally, vitamin K is involved in hormonal balance during pregnancy and heart health. It also supports the immune system. And do not forget that the correct daily supply contributes to the health of the circulatory system, preventing the formation of blood clots. Without enough vitamin K, the body develops anemia caused by a disruption in the production of prothrombin protein. Also, a decrease in its level affects the health of the liver. It turns out



Vitamin K

Vitamin K is a fat-soluble vitamin that plays an important role in blood clotting. It comes in two main forms: phytomenadione, also known as vitamin K1, which is plant-based, and menaquinone, known as vitamin K2, which mainly comes from animals and is synthesized by bacteria in the large intestine.

One of the key functions of vitamin K is its participation in the synthesis of blood clotting factors, in particular prothrombin. Prothrombin is a protein necessary for the formation of blood clots, which play an important role in stopping bleeding. Thanks to vitamin K, platelets can form blood clots to seal damaged blood vessels and prevent blood loss.

Although vitamin K deficiency in the body is rare, its presence in the body is necessary to maintain the normal functioning of the blood clotting system. Vitamin K deficiency can cause bleeding problems and increase the risk of bleeding.

However, vitamin K is not only involved in blood clotting. Recent studies have also discovered its importance for bone health. Vitamin K helps activate proteins necessary for the formation and strengthening of bone tissue. It promotes the accumulation of calcium in bones and reduces the risk of osteoporosis and fractures.

Sources of vitamin K include green leafy vegetables such as spinach, kale, broccoli, as well as meat, eggs and some vegetable oils. With a proper diet, it is possible to ensure adequate vitamin K intake. However, some people may need additional vitamin K through supplements, especially if they have digestive problems or other medical conditions.

It is important to note that before taking supplemental vitamin K supplements, you should consult with your doctor to determine the appropriate dosage and duration of use, as excess vitamin K can also have negative health effects.

In conclusion, vitamin K plays an important role in blood clotting and bone health. It is essential for maintaining normal functioning of the blood clotting system and may help prevent osteoporosis. Regular consumption of foods rich in vitamin K is a key factor in maintaining optimal levels of this vitamin in the body. If you need additional vitamin K, it is recommended to consult your doctor to receive individual recommendations on dosage and method of use.
