Docosahexaenoic acid, better known as DHA, and arachidonic acid, better known as ARA or AA, are fatty acids found in breast milk, as well as in some foods, like fish and eggs. (Fatty acids combine to make fat molecules.) Both DHA and ARA are classified as long-chain polyunsaturated fatty acids (LCPs). They each play important roles in our bodies and health throughout our lifetimes. DHA and ARA play also a very important role in early brain and eye development. Research indicates that DHA is crucial for promoting visual acuity, immune responses, and neural tissue growth. Specifically, studies have shown that omega-3 has a positive impact on cognition, learning, language, motor skills, and behavior in children.ARA is still not a mandatory ingredient, but it can be used as an optional addition. Experts also explicitly support the addition of DHA and ARA to infant formula. Studies have shown that formulas not fortified with these fatty acids may lead to significantly lower fatty acid levels in bottle-fed infants compared to breastfed infants, as breast milk naturally contains ARA [2].
