A study asks: Too much folic acid a cause of autism?

NEW YORK (AP) — For decades, pregnant women and women who may become pregnant have been advised to take folic acid to help prevent certain birth defects.

But a new study suggests it may be possible to get too much of a good thing — very high levels of the vitamin in mothers’ blood was linked to higher risk of autism in their children.

Some experts raised questions about the new research. The researchers themselves said there’s no cause to change current public health recommendations. But they and some other experts say it raises an intriguing question that should be explored.

The findings were to be discussed Wednesday at an autism research conference in Baltimore.

Folate is a vitamin found in foods. A synthetic version, folic acid, is used in supplements and fortified foods.
