A UC Davis MIND Institute study of pregnant mice found that high amounts of folic acid during pregnancy harmed the brain development of embryos. Researchers say the findings indicate that more investigation is needed about the best recommended dosage for pregnant women.
“We believe there’s a Goldilocks effect with folic acid. Too little is not good, too much is not good; you have to get it just right,” said Ralph Green, UC Davis distinguished professor of pathology and medicine and a corresponding author of the study.
The research, published Sept. 30 in Cerebral Cortex, involved pregnant mice who were given either a normal amount of folic acid, 10 times the recommended amount, or none. The offspring of the mice that received the largest amount showed significant brain changes.
“It’s not subtle. It’s substantial,” said Konstantinos Zarbalis, associate professor in the Department of…
