Vitamin K2

I received a newsletter in which claim was made that Vitamin K2 will keep your blood pressure healthy. It outlined three steps to follow to keep blood pressure in the healthy range.

1. Remove calcium from arteries for optimum blood flow, presumably layers of calcium deposits narrow the blood vessels.
2. Relax your arteries. When relaxed, your blood vessels open up wider and allow blood flow easily through.
3. Ease blood vessel constriction by stopping Angiotensin II. It's been shown that blueberries help in inhibiting Angiotensin II enzyme. One study reported this in the Journal of Medicinal Food.

I would appreciate your comments on this report.
