Vitamin B12 and pregnancy

Vitamin B12, or cobalamin, is involved in the synthesis of genetic material, in the metabolism of some amino acids and in the formation of red blood cells. Together with folic acid, helps prevent fetal malformations. It also prevents vascular diseases and maternal anemia.





The requirement does not increase much in pregnancy (from 2,4 μg / day in women of childbearing age to 2,6 μg / day during gestation).

The risks of vitamin B12 deficiency

A vitamin B12 deficiency:

  • increases the risk of spina bifida,
  • increases the risk of other neural tube defects,
  • changes in fetal brain development which can also lead to brain atrophy,
  • it may be associated with an increased risk of miscarriage.

The Risks of Excess Vitamin B12

No problems related to an excess of vitamin B12 have been demonstrated. If taken in excessive quantities, it is easily eliminated from the body through the urine.

Foods with vitamin B21

The main sources of B12 are foods of animal origin, for example:

  • meat (liver in particular),
  • crustaceans
  • dairy products.

Vitamin B12 is absent in foods of plant origin. However, some breakfast cereals are fortified with vitamin B12.

It is therefore important that future mothers follow a vegan and vegetarian diet take a supplement of vitamin B12, as also indicated by the Scientific Society of Vegetarian Nutrition and by the main guidelines on nutrition.
