According to a new study, folic acid is linked to a reduced risk of autism spectrum disorders.
FOX News Radio's Bill Vitka reports:
Mothers who took folic acid around the time they became pregnant are less likely to have children diagnosed with autism.
About 40% less likely according to research in Norway that examined the health records of more than 85,000 children.
Overall, women who take folic acid are 27% less likely to have a baby with autism.
But there is a critical window, four weeks before conception through the eighth week of pregnancy, that matters most when the draw-down in risk can reach that 40% level.
