Abstract

Fifty-two adult male subjects were randomly assigned to one of three possible treatment groups: supplemental ascorbic acid at one of two levels, 500 mg or 1000 mg, or a placebo. Hair and blood samples were taken before vitamin C or placebo supplementation was started and at monthly intervals thereafter for three months. Samples were analyzed for cadmium, lead, and mercury. Results indicate that vitamin C did not significantly affect levels of these metals in either hair or blood samples.

摘要

52名成年男性受试者被随机分配到三个可能的治疗组之一：两种剂量水平（500毫克或1000毫克）的补充维生素C组，或安慰剂组。在开始补充维生素C或安慰剂之前，以及此后三个月每月采集头发和血液样本。对样本进行镉、铅和汞的分析。结果表明，维生素C对头发或血液样本中这些金属的含量没有显著影响。
