Does adding DHA to baby-food formulas actually help?

Does adding DHA to baby-food formulas actually help?

Researchers have investigated this carefully. Here are some highlights of a few studies:

Infants fed a special formula enriched with arachidonic acid (0.44%) and DHA (0.3%) had developmental scores similar to those from infants who were breast fed 4 months.

Another study found that babies fed formulas containing adequate amounts of linoleic and linolenic acids, the precursors of arachidonic acid and DHA, developed normal vision and memory abilities.

Babies given supplements of polyunsaturated fatty acids exhibited superior problem-solving skills, compared to those who did not.

However, some evidence suggests that standard formula is just as good as enriched formula for developing vocabulary and motor skills. This is clearly a multi-faceted question which requires more research to understand clearly.
