Title: The effect of zinc (Zn) supplementation during lactation on maternal Zn status and milk Zn concentrations

Abstract

The objective of this study was to longitudinally evaluate the effect of a dietary Zn supplement on maternal Zn states and milk Zn concentrations under a randomized, controlled, double-blinded study design. Sixty women, 30 {plus minus} 3.8 yrs, received either 15 mg Zn/day or placebo through {ge} 7 mos. of lactation. Dietary intake data, biochemical indices of Zn status and milk Zn concentrations were obtained at monthly intervals. Three day test-weighing was done at 2 wks and 3, 5, and 7 mos. Overall mean daily dietary intake for the non-Zn-supplemented group (n = 28) was 12.9 {plus minus} 2.2 mg, and for the Zn-supplemented group (n = 32), 25.7 {plus minus} 2.9 mg, including an average of 14 mg/d from a supplement. Plasma Zn concentrations did not differ between groups across lactation. Milk Zn concentrations were similar to those published previously and did not differ in monthly means or rate of decline according to group. Maternal Zn outputs to the infants at 2 wks and 3, 5 and 7 mos. were 2.17 {plus minus} 0.7, 0.92 {plus minus} 0.4, 0.72 {plus minus} 0.3, and 0.48 {plus minus} 0.26, respectively. The data suggest that average maternal Zn intake of {ge}10 mg/daymore » during lactation is sufficient to maintain adequate maternal Zn status and milk Zn concentrations.« less
