Vitamin K is easily destroyed by extreme heat, light, alkaline substances, strong acids, radiation, and oxidizing agents. Some research, however, shows that cooking does not significantly diminish vitamin K content in vegetables. Vitamin K is absorbed from the upper small intestine with the help of bile salts and pancreatic juices and carried to the liver where it is utilized in the synthesis of prothrombin – a key blood clotting factor in the body. Vitamin K is stored in small doses within the body. The highest concentrations are found in the liver, the pancreas, and in the bones. Any excess of this vitamin is excreted. High intake of vitamin E and calcium interferes with the absorption of vitamin K.
