Effect of Vitamin D Supplementation on Blood Pressure in Elderly People

The prevalence and incidence of cardiovascular disease (such as Hypertension) increases exponentially with age (McDermott, 2007;) These diseases account for 30% of the global mortality (WHO, 2011). Vitamin D (VD) insufficiency affects as many as half of otherwise healthy adults in developed countries (Holick, 2007). VD is implicated in the control of blood pressure (BP) through inhibition of the renin-angiotensin system (Yamshchikov, 2009), although the role of VD supplementation for prevention and treatment of the HTA is controversial.The purpose of this study was to investigate if VD supplement in elderly people reduces the levels of BP.
