This study, conducted by Indian, Australian, and British research institutes, examined whether vitamin D supplementation can improve vascular function and subsequently decrease the mortality of patients with chronic kidney disease. 120 non-diabetic patients with moderate to severe kidney damage and vitamin D deficiency were involved in the study. The patients received a high-dose vitamin D supplement or placebo at the beginning of the study and after 8 weeks. Among others, blood vessel function and several substances in the blood were measured. After 16 weeks, the measured parameters improved significantly in patients who received the vitamin D supplement, unlike patients in the placebo group. Conclusion: Vitamin D can improve vascular function in patients with chronic kidney disease and vitamin D deficiency. More details can be found in the study.
