Background: Vitamin D deficiency is associated with impaired insulin secretion, glucose intolerance and type 2 diabetes. This study was conducted to investigate the effects of supplementation with 50,000 IU vitamin D on improving serum vitamin D levels and insulin resistance in vitamin D insufficient or deficient type 2 diabetic patients. Methods: In this double blind randomized clinical tria...

Background and Aim: Type 2 diabetes mellitus (T2DM) and vitamin D deficiency are both too common during menopause. Since the effect of different doses of vitamin D supplements on blood sugar, insulin concentration  and insulin resistance are unknown, the present study aimed at investigating the effects of different doses of the vitamin D supplements on visceral fat, blood sugar, insulin co...

Background: There are disputed reports of the beneficial effects of magnetic fields on glucose homeostasis. Continuing from our previous work, we studied the effect of a constant magnetic field on blood glucose and weight gain in laboratory mice. Methods: 28 young, female bALB/c mice were randomly allocated into four groups A, B, C and D. Group A were placed in a constant magnetic field for 20 ...

Background: According to previous studies, vitamin D has an inverse relation with some of the lipid and glucose profiles, and its deficiency is a risk factor for type 2 diabetes and cardiovascular disease. Therefore, the aim of this study was to evaluate the effect of vitamin D (calcitriol) on the blood glucose, lipid and hypertension profile in type 2 diabetic patients. Methods: In this Doubl...

Background: Metabolic syndrome (MetS) is a cluster of the most dangerous risk factors for cardiovascular disease and type 2 diabetes. Vitamin D deficiency may have a role in MetS. The purpose of this study was to determine some of the factors of MetS including abdominal obesity, hypertension (HTN), and impaired fasting blood glucose (IFG) according to the new IDF (International Diabetes Federat...
