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 .
The effects of vitamin D supplementation on maternal and neonatal outcome: A randomized clinical trial
Background : Vitamin D supplementation during pregnancy has been supposed to defend against adverse gestational outcomes . Objective : This r and omized clinical trial study was conducted to assess the effects of 50,000 IU of vitamin D every two weeks supplementation on the incidence of  gestational diabetes ( GDM ) , gestational hypertension , preeclampsia and preterm labor , vitamin D status at term and neonatal outcomes contrasted with pregnant women that received 400 IU vitamin D daily . Material s and Methods : 500 women with gestational age 12 - 16 weeks and serum 25 hydroxy vitamin D ( 25 ( OH ) D ) less than 30 ng/ml r and omly categorized in two groups . Group A received 400 IU vitamin D daily and group B 50,000 IU vitamin D every 2 weeks orally until delivery . Maternal and Neonatal outcomes were assessed in two groups . Results : The incidence of GDM in group B was significantly lower than group A ( 6.7 % versus 13.4 % ) and odds ratio ( 95 % Confidence interval ) was 0.46 ( 0.24 - 0.87 ) ( P=0.01 ) . The mean ± SD level of 25 ( OH ) D at the time of delivery in mothers in group B was significantly higher than A ( 37.9 ± 19.8 versus 27.2 ± 18.8 ng/ml , respectively ) ( P=0.001 ) . There were no differences in the incidence of preeclampsia , gestational hypertension , preterm labor , and low birth weight between two groups . The mean level of 25 ( OH ) D in cord blood of group B was significantly higher than group A ( 37.9 ± 18 versus 29.7 ± 19ng/ml , respectively ) . Anthropometric measures between neonates were not significantly different . Conclusion : Our study showed 50,000 IU vitamin D every 2 weeks decreased the incidence of GDM
