The New York Times just came out with this headline:
Who knew it was that easy?!
Actually, while the headline is impressive, the actual study is small and preliminary. Here's what the article tells us:
In mothers and children with gene variants that affect folate metabolism, not taking prenatal vitamins before conception was associated with an up to sevenfold increase in the risk of autism, the researchers found. Prenatal vitamins are rich in folate.
"Taking prenatal vitamin supplements even before conception is a concrete step concerned parents can take," said Dr. Irva Hertz-Picciotto, the study's senior author and principal investigator of the Charge study.
It certainly can't hurt you or your unborn child to take your vitamins. And of course it's a good idea no matter what. As an autism mom who not only took prenatal vitamins for months before conception but also faithfully attended prenatal fitness classes AND lamaze training, and had her baby with no issues in a hospital setting at full term, I can only say - here's hoping it works for you!
