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 Effect of Vitamin D Supplementation on Adiposity, Blood Glycated Hemoglobin, Serum Leptin and Tumor Necrosis Factor-α in Type 2 Diabetic Patients
Background : Since tumor necrosis factor-α ( TNF-α ) could be one of the risk factors at the development of diabetes complications ; as well as serum leptin deficiency is related to increased susceptibility to infections in diabetic patients , they are potential indices from the preventive medicine viewpoint . This study was conducted to represent the effect of supplemental vitamin D3 on serum leptin , TNF-α and adiposity in type 2 diabetic patients . Methods : In this r and omized double-blind placebo-controlled trial , study sample was selected through type 2 diabetic patients ( n = 51 ) . A total of 26 patients were orally supplemented by vitamin D3 ( 400 IU/d ) ( vitamin D group ) and 25 patients by placebo ( placebo group ) for 14 weeks . The blood glycated hemoglobin ( HbA1c ) and the serum ionized Ca , leptin , TNF-α , and serum 25-hydroxyvitamin D ( 25[OH ] D ) were measured at the two groups in the baseline and postintervention stages . Results : It was shown that despite of theplacebo group , serum 25(OH ) D and serum leptin was significantly increased ( P = 0.001 and P = 0.002 , respectively ) , while serum TNF-α was decreased significantly ( P = 0.001 ) in vitamin D group . The remaining parameters , including body fat mass and HbA1c had no alterations between baseline and postintervention stages in vitamin D group . Conclusions : This study may advocate vitamin D supplementation among type 2 diabetic patients due to its beneficial effects on prevention of diabetes complications
