Vitamin K

Vitamin K
Vitamin K also fat soluble. It is essential for the synthesis of prothrombin a compound involved in the clotting of blood.

Cabbage, spinach, cauliflower, and liver are specially good source of vitamin K, although moderate amounts are found in many other vegetables, as well as in cereals.

The significant symptom of vitamin K deficiency in humans and in animals is the loss of the ability of the blood to clot which is, of course, a dangerous condition that can result in death whenever bleeding from cuts occurs. It is believed that humans ordinarily receive adequate amounts of vitamin K in the diet.
