简要总结
Fatigue is one of the most frequently observed symptoms for company workers, and oxidative stress is regarded as one of its cause. Vitamin C is a well-known antioxidant, and the investigators seek for evidence of the efficacy of high dose vitamin C parenteral supplement on fatigue symptoms of company workers after work.
详细描述
Previous studies dealing with vitamin C were focusing on terminal cancer patients or those with chronic fatigue syndrome. Since used drug dosage and the ways of administering vitamin C were not identical, the results were not consistent throughout those studies. This study is aimed to evaluate the efficacy of high dose vitamin C with parenteral supplement on relieving fatigue for apparently healthy volunteers.
