Ascorbic Acid Does Not Increase the Oxidative Stress Induced by Dietary Iron in C3H Mice1
|
ABSTRACT Iron is a potent prooxidant that can induce lipid peroxidation. Ascorbic acid, a potent antioxidant, has prooxidant effects in the presence of iron in vitro. We investigated whether ascorbic acid and iron co-supplementation in ascorbic acid-sufficient mice increases hepatic oxidative stress. C3H/He mice were fed diets supplemented with iron to 100 mg/kg diet or 300 mg/kg diet with or without ascorbic acid (15 g/kg diet) for 3 wk. Liver iron concentration, malondialdehyde (MDA), gluta...
