Timing Is Key: Vitamin B-12 Supplements for Mothers, Infants
Updated June 24, 2025
Vitamin B-12 is crucial for the healthy growth of babies and children. Infants typically recieve this essential nutrient from their mothers, making maternal B-12 levels during pregnancy and breastfeeding notably critically important.Breast milk serves as a primary B-12 source,especially in the first six months.
Pregnant and lactating women face a heightened risk of B-12 deficiency due to increased nutritional demands. While many obtain sufficient B-12 from animal-based foods, deficiencies pose a meaningful public health challenge in regions with limited access to such diets. Researchers are exploring optimal supplement strategies in these resource-limited settings.
A recent study, spearheaded by Dongqing Wang, assistant professor at George Mason University’s Collage of Public Health, investigated the impact of prenatal and postnatal vitamin B-12 supplements. The findings suggest that prenatal supplements provide a short-term boost to B-12 levels in breast milk. however, postnatal supplements demonstrate more sustained benefits.
Wang emphasized the importance of understanding these impacts for designing effective interventions. “Our findings underscore the importance of prenatal vitamins for short-term benefits in breast milk and postnatal vitamins for more sustained impacts on B-12 adequacy in breast milk; both prenatal and postnatal supplements support healthy growth and development in the baby,” Wang said.
Interestingly, the study also revealed that combining prenatal and postnatal supplements did not necessarily amplify the benefits. The effects of each supplement appeared to diminish when used together, suggesting a potential saturation point.
“It appears that there was a certain plateau in the effect when prenatal and postnatal supplements were used together,” said Wang. “The plateau could meen that either prenatal or postnatal vitamins could correct maternal vitamin B-12 deficiency, but the plateau does not preclude the need for combined prenatal and postnatal supplements through pregnancy and breastfeeding to sustain maternal B-12 levels in populations with high levels of dietary inadequacy.”
What’s next
Further research is needed to determine the ideal dosage and duration of vitamin B-12 supplementation for pregnant and lactating women, particularly in areas where dietary B-12 intake is low. The Thrasher Research Fund provided primary funding for this research.
