Role
B12 works with folate for DNA synthesis and nervous system health. Deficiency can cause anemia and neurological harm.
Sources
Meat, fish, eggs, dairy; fortified plant milks and nutritional yeast for vegetarians.
Important point
Vegans need reliable B12 supplement throughout pregnancy and breastfeeding — diet alone is often insufficient.
Check prenatal labels; blood tests if deficiency is suspected.
