Vitamin K. Properties and Functions

Properties and Functions of Vitamin K
It is primarily antihemorragica. It is essential for the hepatic synthesis of prothrombin from the blood.

The bleeding caused by lack of vitamin K are indistinguishable from those produced by lack of vitamin C and P (bioflavonoids) that these last are due to poor nutrition of the capillaries and occur spontaneously, which is not the case with vitamin K, which needs of a small trauma to trigger bleeding. The other hemorrhages arise spontaneously.

Main sources of Vitamin K
It is primarily found in all leafy green vegetables (cabbage, cauliflower, nettles, alfalfa, soybeans, peas, tomatoes.
