The Claim
Infants exclusively breastfed by vegan mothers with undetected vitamin B12 deficiency develop severe macrocytic anemia and neurological impairment, with symptom onset occurring between 4 and 10 months of age.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Infants who are exclusively breastfed by vegan mothers with low vitamin B12 levels develop severe macrocytic anemia and neurological impairment, with symptoms appearing between 4 and 10 months of age.
See the scientific wording
Infants exclusively breastfed by vegan mothers with undetected vitamin B12 deficiency are at risk of developing severe macrocytic anemia and neurological impairment, with symptoms typically emerging between 4 and 10 months of age.
When a baby gets no vitamin B12 from breast milk because the mother doesn't have enough, the baby's body can't make DNA properly or build the protective coating around nerves. This stops blood cells from growing right, making them too big and few, and damages the baby's brain and nerves, causing weakness and developmental problems.
What the research says
1 studyStudy: Vitamin B12 deficiency in an exclusively breastfed infant born to a vegan mother: a case report
A baby who only drank breast milk from a mom who doesn’t eat any animal products got very sick with anemia and weak muscles because her mom didn’t have enough vitamin B12. When the baby got B12 supplements, she got better.
