DHA and ARA
The newest development in the infant formula market is the use of the supplements docosahexaenoic acid (DHA) and arachidonic acid (ARA). DHA and ARA are fatty acids present in human breast milk. Some medical experts contend that breastfed children have higher IQs than formula-fed children, due to the intake of these fatty acids; however, scientific studies comparing the IQs of breastfed and formula-fed babies have been inconclusive. According to the Food and Drug Administration (FDA), some short-term studies show positive effects on visual and brain development while others cannot confirm any benefits. While there may not be any clear advantages to the supplements, the FDA has approved their use in infant formula as safe.
