Vitamin K has an important role in the body, it is involved in keeping your bones healthy and helping to form blood clots. While generally when you hear of blood clots you think of the negative aspect, they are also an important part of the bodies healing process. When you cut or graze yourself, blood clots form to seal the wound and prevent further blood loss. This is where Vitamin K is important. Without adequate intake, people can experience excessive blood loss when a wound is opened. However deficiency of this vitamin is very rare and usually only occurs in people who have intestinal absorption disorders or who have been using antibiotics for lengthy periods of time. A well balanced diet will usually supply the body with an adequate intake of vitamin K which can be found in green vegetables such as spinach, broccoli and cauliflower.
