Vitamin D Supplements Do Not Improve Blood Pressure In Hypertensive Older Patients

August 12, 2013: 12:00 AM EST
Older patients with high blood pressure are not helped by vitamin D supplementation, according to a British study of 159 people aged 77 or older. Two groups of patients were given either vitamin D or a placebo daily every three months for 12 months. Researchers monitored blood pressure, arterial stiffness, endothelial function, cholesterol level, insulin resistance and b-type natriuretic peptide level. They found no significant effect on blood pressure or on any other of the secondary outcomes. The researchers said it was still possible that vitamin D supplements could benefit cardiovascular health “via non-blood pressure effects”.
