Some proof suggests that surplus ascorbic acid intake may possibly have an affect on copper metabolism in a variety of ways, like inhibition of intestinal absorption and ceruloplasmin allergy oxidase exercise and labilization of ceruloplasmin-sure copper for mobile transportation (Harris and Percival, 1991). Substantial concentrations of plasma ascorbate in untimely infants has become advised to lower ceruloplasmin ferroxidase exercise and thus compromise antioxidant security (Powers et al.
