Breast feeding mothers are more likely to suffer vitamin deficiencies than mothers who bottle-feed. This is because they share a significant amount of nutrients they consume with their baby. In order to maintain healthy levels of vitamin B12, nursing moms must make up the difference by either taking vitamin B12 supplements or increasing their consumption of B12 in their diet.

If I nurse often, is my baby still at risk for becoming deficient in vitamin B12?
Cow’s milk and baby formula are rich sources of vitamin B12, and so is the breast milk of a mother with healthy levels of vitamin B12.
The milk of a nursing mother who has vitamin B12 deficiency, however, will likewise have low levels of vitamin B12.
Furthermore, while an adult could harbor low B12 levels for a long time before showing any symptoms of depletion, a malnourished infant can use up his vitamin B12 stores much more rapidly, leaving a very small window of opportunity for treatment.
If left untreated, vitamin B12 deficiency in infants could lead to:
- Severe vomiting
- Stinted brain development
- Failure to thrive
