Effects of sulphur-containing compounds on plasma redox status in muscle-damaging exercise.

The aim of the study was to compare effects of three-day N-acetylcysteine, alpha-lipoic acid or taurine administration on plasma antioxidant status and oxidative damage markers in healthy men after performing muscle-damaging exercise. Fifty-five healthy and trained men were randomly assigned to N-acetylcysteine (NAC, 1.8 g/day, 3 days), alpha-lipoic acid (ALA, 1.
