Study explores how pre- and postnatal B-12 vitamins improve breast milk vitamin B-12 levels

Babies and children need vitamins, including vitamin B-12, to help their brains and bodies develop and grow. Babies get B-12 from their mothers and can have low levels of B-12 if their mothers had low vitamin levels during pregnancy and breastfeeding. The vitamin B-12 levels of infants strongly depend on maternal levels. Adequacy of vitamin B-12 in breast milk is particularly important for infants during the first six months of life when breastfeeding is highly recommended. Even after the first six months of life, breast milk may continue to be a critical source of vitamin B-12 for infants.
