topicL-Carnitine Fatigue Randomized Trial
claimEvidence on NAC suggests context-dependent effects, with supplementation improving glutathione availability, fatigue resistance, and exercise performance in individuals with low baseline glutathione, while results remain inconsistent in healthy populations.
