What is vitamin K?

Vitamin K is an essential, fat-soluble vitamin crucial to the process of blood clotting. It plays a key role in the production of prothrombin, a protein and clotting factor in the blood. There are two main types of vitamin K: K1 (phylloquinone), found mainly in leafy vegetables such as spinach and kale, and K2 (menaquinone), present in fermented foods and animal products. Vitamin K is also vital for maintaining strong bones and cardiovascular health by regulating calcium in the body.

The importance of vitamin K2

Vitamin K2, in particular, has been shown to play an important role in cardiovascular health. Recent research from the University of Maastricht has revealed that vitamin K2 not only helps prevent arteriosclerosis, but can also help restore elasticity in already stiffened blood vessels. These findings suggest a direct link between adequate levels of vitamin K2 and the reduction of cardiovascular disease risk. Deficiency of vitamin K2 in blood vessel walls is now considered a significant risk for cardiovascular disease, similar to known risk factors such as smoking. This information underscores the importance of adequate vitamin K2 intake for cardiovascular health.

Vitamin K deficiency and symptoms

Vitamin K deficiency can cause serious health problems, mainly related to blood clotting and bone health. The most immediate effects of vitamin K deficiency are an increased tendency to bleed and delayed blood clotting, which can lead to easy bruising and excessive bleeding from injuries. In the long term, vitamin K deficiency can contribute to bone weakness and osteoporosis (osteoporosis) because it plays a crucial role in the metabolism of calcium in bones. Symptoms of deficiency can be subtle, but it is important to stay alert for signs such as frequent nosebleeds, bleeding gums, and excessive menstrual bleeding. Our tests at offer a reliable way to check your vitamin K levels and identify any deficiencies.

Vitamin K and bone health

In addition to its critical function in blood clotting, vitamin K also plays an important role in bone health. It is essential for the modification of osteocalcin, a protein needed for the absorption of calcium in bones. This is especially important for postmenopausal women, who have an increased risk of osteoporosis. Adequate intake of vitamin K, especially vitamin K2, helps maintain bone density and reduces the risk of fractures and osteoporosis.

Who could check his vitamin k value?

Checking vitamin K status is especially important for certain groups of people. This includes individuals with conditions such as Crohn's disease, celiac disease or other conditions that affect the absorption of fat-soluble vitamins. People who have an increased risk of cardiovascular disease or a history of bone problems, such as osteoporosis, should also have their vitamin K levels tested. In addition, it is advisable for the elderly and people taking long-term anticoagulants to monitor their vitamin K levels, given vitamin K's crucial role in blood clotting processes. At, we offer comprehensive tests to determine both vitamin K1 and K2 levels, giving you a complete picture of your vitamin K status and overall health.
