folic acid and speech 
A study by the Norwegian Institute of Public Health has found a link between development that suggests taking supplements before and during pregnancy can reduce the risk of delayed language learning.
“Maternal use of supplements containing folic acid within the period from four weeks before, to eight weeks after conception was associated with a substantially reduced risk of severe language delay in children at age 3 years,” said the study’s lead author Christine Roth.
Women wishing to conceive are already recommended to start taking folic acid supplements as soon as possible – at least four weeks before they begin trying for a baby. Good stores of folic acid has been proven to significantly reduce the risk of spina bifida and other major birth defects. This latest study was conducted over a nine year period and followed nearly 39,000 children up to the age of three.
Mothers were asked to assess their children’s language skills using a six-point language scale. children classified as having a severe language delay were those who, by the age of three, were only using one word or unintelligible sounds. The study found 204 cases of severe language delay. Only 0.4% of women who took folic acid supplements saw severe language delay in their children.
