Vitamin B9 deficiency in pregnant women

The consequences of folic acid deficiency in pregnant women may be dramatic, with developmental abnormalities in maternal tissues, abnormal foetal development, and extremely serious malformations (spina bifida, anencephaly), growth retardation and increased risk of prematurity. It is therefore important to supplement folic acid before and during pregnancy.
