Diabetes Mellitus type II (DM II) is a worldwide disease with a rapidly growing parallel prevalence and adversities affecting multi-body systems. Hence, it is imperative to treat DM II effectively, maintaining glucose homeostasis to avoid complications such as diabetic nephropathy, peripheral neuropathy, and retinopathy. Vitamin D, among many benefits, has positive outcomes on hemoglobin A1c (HbA1c) control. It aids in insulin secretion and sensitivity. We systematically screened four databases for relevant information; PubMed, Medline, PMC, and Google scholar. Inclusion and exclusion criteria were applied, and quality appraisal was then done using certain checklist tools: Newcastle-Ottawa tool, AMSTAR (A Measurement Tool to Assess Systematic Reviews) checklist, SANRA (Scale for the Assessment of Narrative Review Articles) checklist, and Cochrane bias assessment.

Data were collected from 14 articles, of which

  • eight are systematic reviews and meta-analysis,
  • one is a narrative review,
  • five are randomized controlled trials and
  • three are general information about DM II and Vitamin D.

In addition, this article evaluates the clinical significance of Vitamin D administration in DM II from a glucose homeostasis perspective, and complications such as nephropathy, neuropathy, and retinopathy. Vitamin D had a clinical positive impact on glucose level, particularly on hemoglobin A1c (HbA1c) reduction, alleviation of diabetic neuropathy and nephropathy symptoms, and hyperglycemia induced-oxidative stress on the retinal cells.

Conclusions (from PDF)

In this systematic review, the role of Vitamin D supplements and their effect on glucose control and most common complications was evaluated in diabetes mellitus II patients. It was concluded that Vitamin D acts in numerous ways on different systems, and its receptors present in many organs. Upon reviewing several studies, the role of Vitamin D was found to be beneficial in DM II for controlling blood glucose level and hemoglobin A1c level. It increases both insulin sensitivity and insulin secretion. Vitamin D suppresses the inflammatory state in DM II, which in diabetic peripheral neuropathy is crucial. Also, Vitamin D improves nerve conduction and hastens wound healing in cases of diabetic foot. Moreover, it acts as a potent analgesic. In case of diabetic nephropathy, it is very important to maintain its control as it can lead to endstage renal disease. It was noted that in post-Vitamin D administration urinary albumin excretion decreased. The retina is vulnerable to elevated blood sugar as it causes the release of reactive oxygen species, leading to retinal tissue damage. Vitamin D is a potent antioxidant, stimulating antioxidant enzyme to prevent damage caused by such oxidative stress. Diet control and antidiabetic agents are the cornerstones in controlling blood glucose which can slow any disease-associated complication. A future investigation of this systematic review would possibly investigate Vitamin D administration in having positive preventative outcomes on DM II-related complications. Moreover, it is worth examining if Vitamin D should be given to only Vitamin D deficient patients or all diabetic patients.

Overview Diabetes and vitamin D

contains the following

  • Diabetes is 5X more frequent far from the equator
  • Children getting 2,000 IU of vitamin D are 8X less likely to get Type 1 diabetes
  • Obese people get less sun / Vitamin D - and also vitamin D gets lost in fat
  • Sedentary people get less sun / Vitamin D
  • Worldwide Diabetes increase has been concurrent with vitamin D decrease and air conditioning
  • Elderly get 4X less vitamin D from the same amount of sun
        Elderly also spend less time outdoors and have more clothes on
  • All items in category Diabetes and Vitamin D 535 items: both Type 1 and Type 2

Vitamin D appears to both prevent and treat diabetes
