This study, executed by Iranian researchers, aimed to assess the effect of vitamin D supplementation on high blood pressure. During the investigation, patients with low and very low vitamin D levels and high blood pressure were involved. The patients received either a vitamin D supplement or a placebo. Blood pressure was measured before and one and two months after the intervention. The results showed a significant reduction of both upper (systolic) and lower (diastolic) blood pressure in the supplementation group, which suggests a beneficial effect of vitamin D supplementation on (high) blood pressure. The use of vitamin D supplementation can be recommended as adjuvant therapy to treat high blood pressure. Further details can be found in the study.
