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.
