title: The influence of β-alanine supplementation on markers of exercise-induced oxidative stress.
abstract: β-Alanine (BA) has been linked with oxidative protection. This study evaluated antioxidant properties of BA. Twenty-five men consumed BA or placebo for 4 weeks, and completed a 40-min run to induce oxidative stress. Blood draws were taken to measure 8-isoprostane, total antioxidant capacity, superoxide dismutase, and glutathione. BA had no significant influence on reducing exercise-induced oxidative stress. Confidence intervals suggest a reduction in lipid peroxidation. BA supplementation may have little influence as an antioxidant.
