Purpose of review After the short summary of history of primary prevention of neural tube defects by folic acid or folic acid-containing multivitamin supplementation during the periconception period, the three main unsolved problems are highlighted. Recent findings Both intervention trials and observational studies confirmed that this new primary preventive method is effective -beyond the prevention of neural-tube defects - in the reduction of the most common structural birth defects: congenital cardiovascular abnormalities. Nevertheless, this important progress in the field of congenital abnormalities is not appreciated appropriately. The periconception supplementation of both folic acid alone and folic acid-containing multivitamin is useful; however, the available data indicate the higher efficacy of multivitamins in the primary prevention of neural-tube defects and congenital cardiovascular abnormalities. The optimal dose of folic acid is not known though this knowledge would be necessary from both a scientific and practical aspect. Summary Periconception folic acid or folic acid-containing multivitamin supplementation has resulted in a breakthrough in the primary prevention of neural-tube defects, cardiovascular abnormalities and probably some other defects; however, extra efforts are necessary to eliminate folic acid or folic acid-containing multivitamin preventable congenital abnormalities.
