A fat-soluble vitamin with multiple health benefits, vitamin K2 plays a crucial role in bone health. It is interesting to understand its impact on cardiovascular health, and where to find it in food.
What is vitamin K2?
Vitamin K2, also known as menaquinone, is one of the forms of vitamin K present in our diet. Unlike vitamin K1, which is primarily involved in blood clotting, vitamin K2 plays a major role in bone health, preventing calcium from depositing in soft tissues such as arteries, and promoting its fixation in bones. In addition, vitamin K2 is associated with a reduced risk of fractures and cardiovascular disease.
Role of vitamin K2 in bone health
Vitamin K2 plays a crucial role in preserving bone health due to its ability to stimulate the production of specific proteins that regulate calcium metabolism in the body. This function is essential for bone mineralization, a vital process that strengthens bones by integrating calcium into their matrix. Therefore, vitamin K2 helps maintain optimal bone density and reduce the risk of fractures. This action is particularly beneficial in older people, where bone density tends to decrease with age. By incorporating enough vitamin K2 into the diet, through foods such as fermented dairy products, certain types of meat, and eggs, bone health can be effectively supported and contribute to the prevention of osteoporosis and other diseases related to bone weakening.
Benefits of vitamin K2
Vitamin K has many benefits, in all its forms. Form K1 is involved in the healing process, while form K2 is essential in bone mineralization, acting in bone growth and bone tissue renewal.
This vitamin is fundamental for bone metabolism and blood clotting. Indeed, vitamin K is known for its beneficial properties on bone health as it contributes to the maintenance of normal bone structure.
It therefore guarantees the strength of bone mineral mass, essential for human body development. Since teeth are bones, vitamin K2 also protects dental health.
In addition, it helps to fight against arterial calcification by participating in the displacement of calcium to bone tissues.
This vitamin is also very important in blood clotting. It has a hemostatic role, meaning it prevents hemorrhages.
Recent scientific studies have shown that a vitamin K deficiency promotes arterial calcification and, conversely, supplementation with this vitamin ensures arterial health.
Impact of vitamin K2 on cardiovascular health
In addition to its role in bone health, vitamin K2 plays an important role in cardiovascular health by inhibiting arterial calcification. Studies have shown that people with adequate levels of vitamin K2 in their diet have a reduced risk of cardiovascular disease, including coronary heart disease and stroke.
Dietary sources of vitamin K2
Vitamin K2 is mainly found in certain animal products and fermented foods. Among the foods rich in vitamin K2, liver stands out as being particularly concentrated in this nutrient, offering an excellent option for those looking to increase their intake. Eggs, cheese, especially hard varieties, and butter are also good sources of vitamin K2, integrating this vital nutrient into various aspects of daily diet.
As for fermented foods, natto proves to be an exceptionally rich source of vitamin K2. This traditional Japanese dish, prepared from fermented soybeans, is not only appreciated for its nutrient content but also for its beneficial probiotics. Other fermented products can also contribute to vitamin K2 intake, albeit to a lesser extent compared to natto.
Effects of vitamin K2 on blood clotting
Although vitamin K2 is primarily associated with bone and cardiovascular health, it also plays a role in blood clotting. Vitamin K2 contributes to the production of proteins involved in blood clotting, which is essential for preventing excessive bleeding and maintaining a healthy balance of blood clotting.
