Conclusion: vitamin D supplementation during pregnancy improves serum 25 (OH) D concentration and suggests positive effects on overall health condition, length at birth and birth weight. Significant effects were also presented at the length at birth considering any supplemented dose (MD=0.19 CI95%=0.08-0.30 p=0.0010 I2=0%, 1452 participants, low quality evidence) and birth weight in doses higher than 4000IU/day (MD=257.05 (CI95%=137.81-376.29 p<0.0001 I2=14%, 176 participants, moderate quality evidence). Results: the newborn’s overall health condition was presented as Apgar, with a mean difference (MD) of 0.15 (CI95%=0.06-0.25 p=0.002 I2=0%, two studies, 648 participants, moderate quality evidence) at the first minute and 0.11 (CI95%=0.04-0.17 p=0.001 I2=0%, two studies, 648 participants, moderate quality evidence) at the fifth minute. The data was analyzed on RevMan 5.4 software and the quality of evidence on GRADE. Vitamin D for babies, children & adolescents. Randomized controlled trials were searched by evaluating the effects of maternal vitamin D supplementation in neonates.

Methods: this research was conducted in the electronic databases of MEDLINE, LILACS, EMBASE and Cochrane Library until December 2020, using the terms “vitamin D”, “pregnancy”, “vitamin D deficiency”, “infant”, “newborn” and their synonyms. Vitamin D supplementation for breastfed infants is recommended due to low. Abstract Objectives: to assess the effects of vitamin D supplementation during pregnancy on the outcomes of vitamin D concentration in newborns, length at birth, overall health (Apgar), birth weight and maternal vitamin D concentration after childbirth.
