The concentration of zinc (Zn) in human milk declines during lactation with considerable interindividual range and diurnal variations being observed (Sievers et al. 1985). However, knowledge of Zn concentrations in comparable time intervals during consecutive lactation periods in the same individual is limited. Therefore, Zn concentrations were investigated in two exclusively breastfeeding mothers during two lactation periods.
