Sorry, moms: Prenatal vitamins with DHA won't boost your kids' IQ after all

Researchers have some bad news for moms who used DHA supplements while they were pregnant in hopes of boosting their baby's brains: At age 7, kids whose mothers took DHA scored no higher on an IQ test than kids whose moms swallowed capsules that were DHA-free. The results are the latest findings from a study assessing the benefits -- if any -- of giving DHA to babies in utero. They appear in Tuesday's edition of the Journal of the American Medical Assn. DHA, short for docosahexaenoic acid, is an omega-3 fatty acid that plays a key role in brain health. It's essential throughout our lives, and especially during infancy when the brain, eyes and nervous system are developing.
