Randomised control trial indicates micronutrient supplementation may support a more robust maternal microbiome for women with antenatal depression during pregnancy.

Background And Aims: We investigated the effects of high dose dietary micronutrient supplementation or placebo on the human gut microbiome in pregnant women who had moderate symptoms of antenatal depression. There is a significant absence of well-controlled clinical studies that have investigated the dynamic changes of the microbiome during pregnancy and the relationship among diet, microbiome and antenatal depression. This research is among the first to provide an insight into this area of research.
