The Claim
Some athletes take glutathione supplements believing they will enhance performance and reduce fatigue.
Origin
This misconception is fueled by the general antioxidant benefits of glutathione and its theoretical ability to reduce oxidative stress during intense exercise.
What Science Says
Research shows mixed results; while glutathione might help in reducing oxidative stress, significant improvements in athletic performance have not been conclusively demonstrated in well-designed RCTs. Meta-analyses and systematic reviews often highlight a lack of evidence for performance enhancement, suggesting any benefits are marginal at best.
Verdict
Mostly False
