Vitamin K

Dr Craig Hacking et al.

Vitamin K (phylloquinone and menaquinone) are a group of fat soluble vitamins required for blood clotting homeostasis. Menaquinone is synthesised by normal flora in the intestine. Vitamin K serves as a coenzyme for the clotting factors 2, 7, 9 and 10. Warfarin inhibits vitamin K.

Pathological manifestations are rare. Hypervitaminosis K can lead to jaundice and anaemia in the newborn.
