This meta- analysis suggests that vitamin D supplementation improves indices of glycemic control ( FBG , HOMA-IR , and HbA1C ) in patients with diabetes mellitus .
Hence , vitamin D supplements may be of potential therapeutic value in diabetic patients , as an adjuvant therapy along with other treatments
BACKGROUND AND PURPOSE This systematic review and meta- analysis aim ed to assess the effects of vitamin D supplements on indices of glycemic control [ homeostatic model assessment -insulin resistance ( HOMA-IR ) , hemoglobin A1C ( HbA1C ) , fasting blood glucose ( FBG ) , and quantitative insulin-sensitivity check index ( QUICKI ) and lipid profile in diabetic patients .
Effect of Vitamin D Supplementation on the Incidence of Gestational Diabetes
Background : The aim of this study was survey of the effect of Vitamin D supplementation on the incidence of  gestational diabetes ( GDM ) in pregnant women . Material s and Methods : This r and omized clinical trial was conducted at Alzahra and Shahid Beheshti Hospital in Isfahan , Iran , from January , 2013 to January , 2014 on 210 pregnant women referred to gynecology clinics . Serum levels of Vitamin D were measured , and those with lower serum levels of 10 nmol/L r and omly divided into two groups of A and B. Pregnant women with normal Vitamin D level assigned as Group C. Group A was given 50,000 IU Vitamin D supplement every 2 weeks for 10 weeks , and Group B were given the omega-3 pearl as placebo . Then , the incidence of GDM was measured in 24–26 weeks of pregnancy with glucose tolerance test and compared in three groups . Data were analyzed using SPSS version 20 by descriptive statistics , Chi-square and Logistic regression . Results : The mean age of participants was 24.76 years ( 8.02 st and ard deviation , range 16–36 years ) . The incidence of GDM at 24–26 weeks gestational age were 8.57 % in normal Vitamin D group , 10.00 % in Vitamin D deficiency with treatment group , and 11.43 % in Vitamin D deficiency without treatment group . The difference between groups in terms of incidence of GDM was not statistically significant ( P = 0.112 ) . Conclusion : Vitamin D supplementation had not effect on incidence of GDM during pregnancy
