Vitamin K2
Vitamin K2
Vitamin K2 (pronunciation: /ˈvaɪtəmɪn 'keɪ 'tu:/), also known as menaquinone, is a type of Vitamin K that plays a crucial role in blood clotting and bone and heart health.
Etymology
The term "Vitamin K" comes from the German word "Koagulationsvitamin," which refers to the vitamin's ability to help blood clot. The "2" in Vitamin K2 distinguishes it from other forms of Vitamin K, such as Vitamin K1 and Vitamin K3.
Function
Vitamin K2 is responsible for the activation of proteins that regulate calcium deposits in the body. It helps to keep calcium in bones and teeth and out of arteries and muscles.
Sources
Vitamin K2 is primarily found in certain types of fermented foods like natto, a Japanese dish made from fermented soybeans. It can also be found in some cheeses, such as Gouda and Brie, as well as in animal products like liver and egg yolks.
