The aim of this study was to investigate the effects of limited food intake (LFI) (24, 48 and 120 h) and a single i.p. dose of vitamin C supplementation (500 mg/kg) on serum glucose and C-peptide levels, and pancreatic insulin and glucagon levels in guinea pigs. The highest serum glucose levels were found after vitamin C supplementation plus LFI for 48 h (LFI 48). Serum C-peptide levels were no...

BACKGROUND There is increasing evidence for the presence of oxidative stress and vitamin C deficiency in dialysis patients. Limited data, however, are available regarding the effects of vitamin C supplementation on oxidative stress and inflammation markers in such patients. METHODS We ran a prospective, randomized, open-label trial to assess the effects of oral vitamin C supplementation (250 ...

Inadequate dietary intake of vitamin C results in hypovitaminosis C, defined as a plasma ascorbate concentration ≤23 μmol/L. Our objective was to carry out a retrospective analysis of two vitamin C supplementation studies to determine whether supplementation with 50 mg/day vitamin C is sufficient to restore adequate ascorbate status (≥50 μmol/L) in individuals with hypovitaminosis C. Plasma asc...
