1 The objective of our study was to evaluate the effects of the administration of two dosages of vitamin C (Vit-C) (0.5 and 1g/day, vs. placebo) in elderly patients with type 2 diabetes mellitus on the intracellular levels of Vit-C and glutathione, and on the lipid peroxidation markers and vitamin E (Vit-E) content of low-density lipoprotein (LDL) and on LDL susceptibility to gamma radiolysis-induced peroxidation.

3 In patients on 1 g Vit-C/day versus placebo, a significant increase was also observed in cellular reduced glutathione (0.93+/-0.70 vs. 0.33+/-0.27), in Vit-C (5.66+/-2.00 vs. 2.72+/-1.88) and in vitamin E content of LDL (1.98+/-0.38 vs. 1.48+/-0.40). Vitamin E vitrin Homo sapiens
4 In conclusion, Vit-C has a dose-dependent effect on the cellular contents of antioxidants and on vitamin E content of LDL in elderly patients with type 2 DM. Vitamin E vitrin Homo sapiens
