introduction: the pathogenesis of diabetic disorders are unknown and may be multifactorial. one of the most important mechanisms of complications is glycosilation of proteins such as haemoglobin. structurally, vitamin c is similar to glucose and can act as glucose in many chemical reactions, therefore it may prevent non- enzymatic glycosilation of proteins such as haemoglobin and lipoproteins. ...

  Purpose: The aim of this study was to investigate the effect of four weeks supplementation of   vitamin C on serum levels of total antioxidant capacity and malondialdehyde among inactive   men after an eccentric exercise.   Materials and Methods: Twenty non-athletic healthy volunteer men (24 ± 1.6 years old,   22.59 ± 2.62 body fat percentage and 48.96 ± 3.58 mL/kg/min maximum oxygen uptake) ...

abstract          background and objective: vitamins c and e are  the two main antioxidants involved in prevention of type 2 diabetes, by reducing oxidative stress. the aim of this study was to evaluate the effects of vitamins c and e supplementation independently, on serum levels of insulin, high sensitivity c-reactive protein (hs-crp) and resistin in people with type 2 diabetes.         metho...

background: to assess the effect of supplementation with vitamins a, e and c and ω-3 fatty acids on lipid peroxidation in strepto zotocin (stz) induced diabetic rats. methods: sixty four male wistar rats weighting 250g were divided into four groups as normal control, diabetic control, dia betic with vitamin a, e as well as c supplementation and diabetic with ω-3 fatty acids supplementation. aft...

Antioxidant vitamins have been reported to be associated with an improvement in blood lipid profiles, but results are not consistent. The present study was designed to determine whether long-term vitamin C supplementation could alter serum lipid concentrations in subjects who completed a 5-year population-based double-blind intervention trial. A total of 439 Japanese subjects with atrophic gast...

Although vitamin C supplements were consumed for health maintenance and fatigue recovery, the effects of high doses of vitamin C supplement remains controversial. Our study performed the effects of 100 mg and 2,000 mg vitamin C supplements on plasma and urinary vitamin C concentration in Korean women. Twenty-four women completed the 4 weeks intervention.
