However, the deficiency of it can harden the blood vessels, making it more difficult for the heart to pump out blood to the rest of the artery system. As a result, more pressure is needed to be put in pumping blood out, which eventually results in high blood pressure in individual. Therefore, consuming Vitamin K ensures that the arteries remain elastic, and blood pumping remains an easy and smooth job for the heart. As a result, the blood pressure remains to a moderate level.
Cardiovascular diseases is one of the leading causes of death in our world today. Several research has shown that Vitamin K aids in combating and preventing cardiovascular diseases.
