The effects of vitamin C supplementation on blood and hair levels of cadmium, lead, and mercury

E J Calabrese et al. Ann N Y Acad Sci. 1987.

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.
