Overall , this meta- analysis shows that in diabetic patients , taking vitamin D had significant effects on hs-CRP and MDA levels , and significantly increased NO , TAC and GSH levels
In this systematic review and meta- analysis of r and omized controlled trials ( RCTs ) , the effects of vitamin D supplementation on biomarkers of inflammation and oxidative stress in diabetic patients are summarized .
Vitamin D supplementation in obese type 2 diabetes subjects in Ajman, UAE: a randomized controlled double-blinded clinical trial
Objectives : To study the effect of Vitamin D3 supplementation on metabolic control in an obese type 2 diabetes Emirati population . Methods : This r and omized double-blind clinical trial was conducted with 87 vitamin D-deficient obese , type 2 diabetic participants . The vitamin D-group ( n=45 ) and the placebo group ( n=42 ) were matched for gender , age , HbA1c and 25-hydroxy vitamin D ( 25(OH ) D ) at the baseline . The study was divided into two phases of 3 months each ; in phase 1 , the vitamin D-group received 6000 IU vitamin D3/day followed by 3000 IU vitamin D3/day in phase 2 , whereas the placebo group ( n=42 ) received matching placebo . Results : After supplementation , serum 25(OH ) D peaked in the vitamin D-group in phase 1 ( 77.2±30.1 nmol/l , P=0.003 ) followed by a decrease in the phase 2 ( 61.4±18.8 nmol/l , P=0.006 ) , although this was higher compared with baseline . In the placebo group , no difference was observed in the serum 25(OH ) D levels throughout the intervention . Relative to baseline serum , parathyroid hormone decreased 24 % ( P=0.003 ) in the vitamin D-group in phase 2 , but remained unchanged in the placebo group . No significant changes were observed in blood pressure , fasting blood glucose , HbA1c , C-peptide , creatinine , phosphorous , alkaline phosphatase , lipids , C-reactive protein or thyroid stimulating hormone concentrations compared with baseline in either group . Conclusions : Six months of vitamin D3 supplementation to vitamin D-deficient obese type 2 diabetes patients in the UAE normalized the vitamin D status and reduced the incidence of eucalcemic parathyroid hormone elevation but showed no effect on the metabolic control
