Research shows that DHA, an omega-3 fatty acid that's been shown to boost a baby's brain development, is good for children of all ages. Here's how much DHA kids need -- and the best sources, from David Perlmutter, M.D., a leading expert in the field and a neurologist in Naples, FL:
Benefit: DHA during pregnancy can increase a child's IQ by age 4.
How much: Pregnant women should get 400 mg or more daily. Prenatal vitamins don't have enough, so take a vegetarian supplement -- not fish oil, which can contain mercury.
Newborns to 6 months
Benefit: Better hand-eye coordination at 2 years compared with babies who didn't get enough.
How much: Breastfed babies get all they need from you as long as you're taking a daily supplement of 400 mg or more. If you're not nursing, look for formula containing at least 19 mg of DHA per five-ounce serving.
6 months to 2 years
Benefit: DHA jump starts the production of a hormone that's crucial for brain development during this time of rapid growth.
How much: 100 mg daily or more from foods marked DHA-enriched, like some yogurt, cereal, and -- once your child turns 1 -- milk and eggs. And serve wild Alaskan salmon, the best natural food source that's also low in mercury. Up to four 1- to 2-ounce servings a week is safe.
Kids 2 to 5 years
Benefit: Low levels of DHA in children have been linked to an increased risk of ADHD, vision problems, and depression.
How much: 200 mg daily or more from DHA-enriched foods (see above) and wild Alaskan salmon (up to four 3-ounce servings per week).
