What is Vitamin K2?
Vitamin K2 can be traced back to the 1600s, back to when the Samurai warriors in Japan began to consume a fermented soybean dish called natto. Historical diets provided enough Vitamin K2 to prevent deficiencies, however commercial changes in food preparation and storage have likely reduced the amount of Vitamin K2 accessible in our diets. It wasn’t until 1935 when the Danish scientist Henrik Dam noticed that feeding chicks with bleeding gums an extremely low-fat diet could be counteracted by supplying the animals with a fat-soluble factor. Edward Adelbert Doisy discovered and synthesised the chemical structure of Vitamin K a few years later, giving cause for both Dam and Doisy to share the Nobel Prize in 1943 in medicine.
The chemical name of Vitamin K2 is Menaquinone, a fat-soluble vitamin that is stored in the liver. Vitamin K2 exists in nine forms (MK-1 to MK-9) with the most important forms being MK-4, MK-7 and MK-9. Natural dietary sources of Vitamin K2 include dairy, eggs, yoghurt, cheese, spinach, green leafy vegetables, and the previously mentioned Japanese natto.
Benefits of Vitamin K2
Vitamin K plays a role in the contribution to normal blood clotting, essential for blood coagulation to close wounds and prevent excessive blood loss. The fat-soluble vitamin also aids the maintenance of normal bones, keeping bones healthy by helping the body to absorb Calcium.
