Summary
This study, conducted by the University of Auckland, New Zealand, investigated the effect of vitamin D supplementation on primary care visits during pregnancy and infancy due to acute respiratory infections. Additionally, the required dose to achieve a normal vitamin D status during infancy was determined. To this end, healthy pregnant women were assigned in either a group receiving higher-dose vitamin D (86 women), a lower dose of vitamin D (87 women), or a placebo product (87 women). At the end of the study period, there was a lower number of primary care visits for acute respiratory infections by infants in the group that received a higher dose of vitamin D. For more details, please see the study.
