Observational and experimental data reinforce the concept that vitamin D is associated with the pathogenesis of arterial hypertension. We investigated the efect of a single dose of 100,000 IU of cholecalciferol, in ofce blood pressure (BP), and 24-h ambulatory blood pressure monitoring (ABPM) in patients with type 2 diabetes mellitus (DM), hypertension, and hypovitaminosis D. Fortythree patients were randomized to a placebo or cholecalciferol group. BP was assessed by ofce measurements and 24-h ABPM, before and after intervention. At week 8, a greater decrease in median ABPM values was observed in cholecalciferol supplementation than in the placebo group for systolic 24-h (− 7.5 vs. − 1; P= 0.02), systolic daytime (− 7 vs. − 1; P= 0.007), systolic nighttime (− 7.0 vs. 3; P= 0.009), diastolic 24-h (− 3.5 vs. − 1; P= 0.037), and daytime DBP (− 5 vs. 0; P= 0.01). Ofce DBP was also reduced after vitamin D supplementation. A single dose of vitamin D3 improves BP in patients with type 2 diabetes, hypertension, and vitamin D insufciency, regardless of vitamin D normalization. Vitamin D supplementation could be a valuable tool to treat patients with type 2 DM, hypertension, and hypovitaminosis D.
