Effect of antioxidant supplementation on urine and blood markers of oxidative stress during extended moderate-altitude training

“…Vitamin E acts as a lipid-soluble antioxidant that scavenges peroxyl and hydroxyl radicals, acting as a lipid-peroxidation-chain-breaking antioxidant and as a cell membrane lipid stabilizer. Studies indicate that supplementation of vitamin E reduces oxidative stress and suggest that vitamin E requirements increase with exercise [11][12][13][14][15][16]. Studies conducted at higher altitudes indicate that vitamin E supplementation may attenuate the decrease in physical performance [9,[17][18][19].…”
