Why we need foods high in Vitamin K ?

Vitamin K plays an important role in the process of blood clotting (essential in the fight against hemorrhage) and keeps the arteries and blood vessels supple and in good condition. Vitamin K also contributes to a quick release of calcium in bones and teeth. Daily requirement of vitamin K is about 75 micrograms ; deficiencies are however very rare because any meal usually provides 4 to 5 times the recommended daily dose.
