Researchers tracked 159 patients with isolated systolic hypertension ages 70 and older and found no significant differences in blood pressure levels between those who received vitamin D supplements or a placebo for one year. Vitamin D supplementation also failed to improve other measures of cardiovascular health, including serum calcium levels and arterial stiffness, in the randomized trial. The findings appear in the journal JAMA Internal Medicine.
