Vitamin k – key role in the body and consequences of deficiency

Vitamin K, despite the fact that it is often overshadowed by other known vitamins, plays an extremely important role in our body. It is necessary for the proper functioning of many physiological processes. In this article, we will learn about the functions of vitamin K in the body, where it can be found, what are the symptoms of deficiency and how much we need this vitamin every day.

Vitamin k – role in the body

Vitamin K is a key factor in the blood clotting process. Without it, our blood would not be able to clot, which could lead to severe hemorrhages even with the slightest damage to blood vessels. Vitamin K influences the synthesis of a clotting factor known as prothrombin, which is necessary for proper blood clotting.

Additionally, vitamin K plays an important role in bone health. It helps in the mineralization of bone tissue and prevents bone loss, which is especially important for older people who are more susceptible to osteoporosis.

Not only the circulatory system and bones benefit from vitamin K. This substance also plays a role in the calcification of soft tissues, such as blood vessels and nerves, which helps maintain their proper structure and function.

Vitamin k – sources

Sources of vitamin K are divided into two main groups: vitamin K1 (phylloquinone) and vitamin K2 (menaquinone). Vitamin K1 is found mainly in leafy vegetables such as spinach, kale and broccoli. Vitamin K2, on the other hand, can be found in animal products such as meat and eggs, as well as in fermented products, such as fermented soy products, cheese and kefir.

Vitamin k – deficiency symptoms

Vitamin K deficiency can lead to serious health problems. The most important effect of deficiency is a tendency to bleed, which may be difficult to control. There may be bleeding from the nose, gums and even internal bleeding, which pose a real threat to life.

Additionally, vitamin K deficiency can negatively impact bone health, leading to increased susceptibility to fractures and osteoporosis.

Vitamin k – requirement

The need for vitamin K depends on age, gender and general health. For children and adults, the recommended daily intake of vitamin K is approximately 120 micrograms. However, in periods of life when the need for vitamin K is higher, for example in pregnant women, it may be necessary to increase its supply through an appropriate diet or supplementation.

Your suggestions

To maintain appropriate levels of vitamin K in the body, it is worth including products containing this vitamin in your diet. Spinach, broccoli, eggs, cheese and kefir are just some of the rich sources of vitamin K. If you have doubts about your need for vitamin K or suspect a deficiency, it is always worth consulting a doctor or dietitian who can conduct appropriate tests and advise on appropriate supplementation. .
