Glutathione Oxidation

This study investigated if vitamin C supplementation before and after eccentric exercise could reduce muscle soreness (MS), oxidative stress, and muscle function. Eighteen healthy men randomly assigned to either a placebo (P) or vitamin C (VC) (3 g/d) treatment group took pills for 2 wk prior and 4 d after performing 70 eccentric elbow extensions with their non-dominant arm. MS increased in both groups with significantly reduced MS for the first 24 h with VC. Range of motion was reduced equally in both groups after the exercise (P ≥ 0.05). Muscle force declined equally and was unaffected by treatment. VC attenuated the creatine kinase (CK) increase at 48 h after exercise with similar CK after this time. Gluta-thione ratio (oxidized glutathione/total glutathione) was significantly increased at 4 and 24 h with P but VC prevented this change. These data suggest that vitamin C pretreatment can reduce MS, delay CK increase, and prevent blood glutathione oxidation with little influence on muscle function loss.

Type 2 diabetes mellitus (DM) is a chronic disease which deteriorates the quality of life with time. Type 2 DM accounts for more than 90% cases of diabetes mellitus as compared to other types of this disease. There is significant oxidative stress in type 2 DM which plays an important role in the pathogenesis of disease. In order to combat this oxidative stress antioxidant supplements have to be added as add on therapy along with treatment of type 2 DM. Vitamin C is the safest antioxidant which plays significant role in diminishing the oxidative stress. The vitamin C supplementation have good control of FBS and HbA1c and therefore helps in achieving better glycemic control along with prevention of lipid abnormalities.

AbstractThe aim of this study was to investigate the longitudinal changes in serum paraoxonase-1 (PON1) activity from preconception throughout normal pregnancy and their relationships with maternal dietary vitamin C and E intake. The study was performed in 35 women (studied at preconception, at 8, 20 and 32weeks of pregnancy, and at labour). PON1 activity decreased significantly from 145.8 (109.8–198.8) U/L at preconception to 111.1 (85.3–179.9) U/L (p<0.01) at 32weeks and 100.4 (54.7–171.4) U/L (p<0.001) at labour. There was a direct association between vitamin C intake and PON1 at week 32 (p=0.018). We conclude that adequate vitamin C intake in pregnant women may merit consideration, since vitamin C supplementation has proved beneficial in the prevention of preeclampsia in women at increased risk of this condition.Clin Chem Lab Med 2006;44:880–2.
