Zinc and copper nutriture of women taking oral contraceptive agents.

A cross-sectional and follow-up study of young women taking oral contraceptive agents revealed a marked increase in serum copper levels. This increase was significant after the taking of oral contraceptive agents for 3 months. No significant effect of oral contraceptive agents on serum zinc and hair levels or copper were observed. There was no correlation between duration of oral contraceptive agent therapy and zinc or copper concentrations in serum or hair. Serum and hair concentration of zinc or copper were also not significantly correlated.
