Vitamin D & high blood pressure

This a recent review of the evidence for and mechanisms of the role of Vitamin D in arterial hypertension in Nature Reviews Cardiology. Not surprisingly, the investigators found the antihypertensive effect of Vitamin D to be especially prominent when both deficiency and elevated blood pressure are present. "Thus, in view of the relatively safe and inexpensive way in which vitamin D can be supplemented, we believe that vitamin D supplementation should be prescribed to patients with hypertension and 25-hydroxyvitamin D levels below target values."
