What is it?
Vitamin K (K from "Koagulations-Vitamin" in German, Danish, Swedish and Norwegian) denotes
a group of lipophilic, hydrophobic vitamins that are needed for the posttranslational modification
of certain proteins, mostly required for blood coagulation. Chemically they are 2-methyl-1,
Vitamin K2 (menaquinone, menatetrenone) is normally produced by bacteria in the intestines, and dietary deficiency is extremely rare unless the intestines are heavily damaged or are unable to absorb the molecule.
