The administration of N-acetylcysteine reduces oxidative stress and regulates glutathione metabolism in the blood cells of workers exposed to lead

This randomized controlled trial investigated the effects of N-acetylcysteine (NAC) supplementation on oxidative stress and glutathione metabolism in 171 lead-exposed male workers. Participants were divided into four groups: a control group and three groups receiving NAC at doses of 200 mg, 400 mg, or 800 mg per day for 12
