Lower levels of 25-hydroxyvitamin D₃ are associated with a higher prevalence of microvascular complications in patients with type 2 diabetes

Abstract

We found an inverse and independent relationship between circulating 25(OH)D levels and the prevalence of microvascular complications in patients with type 2 diabetes. However, vitamin D may be simply a marker and causality cannot be implied from our cross-sectional study. Whether vitamin D supplementation in patients with type 2 diabetes may have beneficial effects on the risk of microvascular complications remains to be investigated.
