Abstract: Objective The present study was to examine the importance of magnesium on the rat antioxidant status.Methods Male Wistar rats were fed with diet containing 0.07%,0.27% and 0.47% of magnesium,respectively.The magnesium serum level and biochemical function analysis were performed after the animals were sacrificed.Results Adding of 0.2% or 0.4% magnesium in diet significantly enhanced activities of antioxidase(P<0.05),and significantly decreased MDA level(P<0.05).There was a significantly difference in the activities of antioxidase between organic magnesium and inorganic magnesium(P<0.05).Conclusion Magnesium-supplemented animals show an decreased susceptibility to an in vivo oxidative stress.
