Excessive mineral intake may prolong the pregnancy

In September 2019 researchers from Australia published the results of their study to assess the the effects of supplements during pregnancy on nutrient status and birth outcomes. A total of 127 women were involved in the study. Fasting blood samples were taken between 180 and 210 days gestation and dietary information collected. Results showed that supplement use appeared to have no significant influence on blood levels of trace elements or the incidence of hypertensive disorders, gestational diabetes, preterm birth or infant birthweight. Dietary selenium, zinc and iodine, however, were seen to be significantly higher in women giving birth at 41 weeks and over. An analysis suggested that excessive mineral intake contributed to a prolonged pregnancy. Further research is therefore required to determine individual needs and to eliminate the potential for harm before recommending pregnancy supplements.
