Vitamin K 1-deficiency may occur by disturbed intestinal uptake (such as would occur in a bile duct obstruction), by therapeutic or accidental intake of a vitamin K 1-antagonist such as warfarin, or, very rarely, by nutritional vitamin K 1 deficiency. As a result, Gla-residues are inadequately formed and the Gla-proteins are insufficiently active.
Vitamin K is a family of structurally similar, fat-soluble vitamers found in foods and marketed as dietary supplements. [1] The human body requires vitamin K for post-synthesis modification of certain proteins that are required for blood coagulation ("K" from Danish koagulation, for "coagulation") or for controlling binding of calcium in bones and other tissues. [2]
Phytomenadione, also known as vitamin K 1 or phylloquinone, is a vitamin found in food and used as a dietary supplement. [6] [7] It is on the World Health Organization's List of Essential Medicines. [8] It is used to treat certain bleeding disorders, [7] including warfarin overdose, vitamin K deficiency, and obstructive jaundice. [7]

Vitamin K reactions are adverse side effects that may occur after injection with vitamin K. [1] The liver utilizes vitamin K to produce coagulation factors that help the body form blood clots which prevent excessive bleeding. [2] [3] Vitamin K injections are administered to newborns as a preventative measure to reduce the risk of hemorrhagic ...
Vitamin K deficiency leads to the risk of blood coagulation problems due to impaired production of clotting factors II, VII, IX, X, protein C and protein S by the liver. More rarely VKDB can be caused by maternal medicines causing vitamin K deficiency in the newborn. [2] VKDB can largely be prevented by prophylactic supplementation of vitamin K ...
Menadione is converted to vitamin K 2 (specifically, MK-4) by the prenyltransferase action of vertebrate UBIAD1. [4] This reaction requires the hydroquinone (reduced) form of K 3, menadiol, produced by NQO1. [6] Menadione is also a circulating form of vitamin K, produced in small amounts (1–5%) after intestinal absorption of K 1 and K 2.
