Periconceptional supplementation with folate with or without multivitamins to prevent neural tube defects

Studies suggest that fetal growth and development are influenced by the nutritional status of the mother in the period before she conceives and at the time of conception. This periconceptional period is therefore considered to be an important time for interventions that optimize maternal health and thereby confer benefits to the next generation.

Folic acid is used in supplements and fortified foods to reduce the occurrence of neural tube defects such as spina bifida.

In the periconceptional period, the latest evidence suggests that neural tube defects can be prevented with folate supplementation, either alone or in combination with other vitamins and minerals.
