Urinary Iodine, Perchlorate, and Thiocyanate Concentrations in U.S. Lactating Women

Abstract

Lactating women in three U.S. geographic regions are iodine sufficient with an overall median UIC of 143 μg/L. Given ubiquitous exposure to perchlorate and thiocyanate, adequate iodine nutrition should be emphasized, along with consideration to decrease these exposures in lactating women to protect developing infants.
