According to a 2011 study (1), the researchers found that mothers of children with autism were less likely than those of typically developing children to report having taken prenatal vitamins during the 3 months before pregnancy or the first month of pregnancy. Greater risk was also observed for children whose mothers had other one-carbon metabolism pathway gene variants and reported no prenatal vitamin intake.
Their conclusion is that periconceptional use of prenatal vitamins may reduce the risk of having children with autism, especially for genetically susceptible mothers and children.
