Allen HL. Multiple micronutrients in pregnancy and lactation: an overview. Am J Clin Nutr. May 2005;81(5):1206S-1212S.
This overview of micronutrients during pregnancy and lactation emphasized two relatively neglected issues: (1) the importance of maternal micronutrient status in the periconceptional period, as well as throughout pregnancy and lactation, and (2) the occurrence of simultaneous multiple micronutrient deficiencies when diets are poor. Unfortunately, information is lacking on the optimal formulation of micronutrient supplements for pregnant and lactating women.
