The Role of DHA and ARA in Infant Formula Development: Supporting Your Baby’s Brain and Eye Health

As a new parent, you want to give your baby the very best start in life. Among the many nutrients found in breast milk, two stand out for their critical role in early development: DHA (docosahexaenoic acid) and ARA (arachidonic acid). These long-chain polyunsaturated fatty acids (LCPUFAs) are now commonly added to infant formulas, but many parents still wonder what they actually do and why they matter.

In this article, we’ll break down the science behind DHA and ARA, their impact on infant brain and eye development, and how modern formulas—like those from Bubs—incorporate these ingredients to support your growing baby.

What Are DHA and ARA?

DHA and ARA are types of omega-3 and omega-6 fatty acids, respectively. DHA is a key structural component of the brain and retina, while ARA supports brain growth and helps regulate inflammation. Both are naturally abundant in breast milk, but until recently, most infant formulas did not include them. Today, research shows that supplementing formula with DHA and ARA can help formula-fed babies achieve developmental outcomes closer to those of breastfed infants.

The human body can produce small amounts of DHA and ARA from other fatty acids, but the conversion is inefficient—especially in newborns. That’s why many health organizations, including the World Health Organization and the European Food Safety Authority, recommend that infant formulas contain DHA and ARA at levels similar to those found in breast milk.

• DHA supports brain development and cognitive function.
• ARA contributes to healthy immune responses and cell growth.
• Both are naturally found in breast milk and now added to many premium formulas.

How DHA and ARA Support Infant Brain and Eye Development

During the first two years of life, a baby’s brain grows more rapidly than at any other time. DHA accumulates in the gray matter of the brain and in the retina of the eye, where it helps transmit visual signals. Studies have shown that infants who receive DHA-supplemented formula demonstrate better visual acuity and cognitive performance in early childhood.

ARA works alongside DHA to support neural membrane fluidity and signaling. While DHA gets most of the attention, ARA is equally important—some research suggests that a balance of both fatty acids is necessary for optimal development. That’s why quality formulas, such as Bubs Organic Grass Fed Follow-on Formula Stage 2, are formulated with both DHA and ARA from plant-based sources.

• DHA is critical for visual and cognitive development.
• ARA supports overall brain growth and immune function.
• A balanced DHA-to-ARA ratio is key for formula-fed babies.

What to Look for in a DHA- and ARA-Enriched Formula

Not all infant formulas are created equal. When choosing a formula with DHA and ARA, look for products that list these ingredients explicitly on the label. The source matters too—many premium formulas use plant-based DHA from algal oil and ARA from fungal oil, which are sustainable and free from contaminants.

For example, Bubs Easy-digest Goat Milk Infant Formula Stage 1 is a great option for parents seeking a gentle, easy-to-digest formula that still provides essential DHA and ARA. Goat milk formulas are naturally closer to breast milk in protein structure, and when combined with added DHA and ARA, they offer a comprehensive nutritional profile for sensitive tummies.

• Check the label for DHA and ARA content (typically 10–20 mg per serving).
• Choose formulas with plant-based DHA and ARA when possible.
• Consider your baby’s digestive needs—goat milk formulas are often gentler.

The Science Behind DHA and ARA Supplementation

Multiple clinical trials have evaluated the effects of DHA and ARA in infant formula. A landmark study published in the journal Pediatrics found that infants fed formula with DHA and ARA had higher scores on the Bayley Scales of Infant Development at 18 months compared to those fed unsupplemented formula. Other research has linked DHA intake to improved problem-solving skills and language development in early childhood.

The amount of DHA in formula matters. While earlier formulas contained lower levels (around 0.15% of total fatty acids), newer recommendations suggest levels closer to 0.3%–0.5% to match the average intake of breastfed infants. Brands like Bubs adhere to these updated guidelines, ensuring their products provide meaningful amounts of DHA and ARA.

• Clinical studies show improved cognitive and visual outcomes with DHA/ARA.
• Higher DHA levels (0.3%–0.5%) are now recommended.
• Look for formulas that meet current scientific standards.

Are There Any Risks or Side Effects?

DHA and ARA are generally recognized as safe for infants. The U.S. Food and Drug Administration (FDA) has approved their use in infant formula, and they have been used for decades without significant adverse effects. Some parents worry about allergies, but DHA from algal oil and ARA from fungal oil are free from common allergens like fish, soy, and gluten.

However, it’s always wise to consult your pediatrician before switching formulas, especially if your baby has a known sensitivity or medical condition. For most healthy infants, DHA- and ARA-enriched formulas are an excellent choice that helps bridge the nutritional gap between formula and breast milk.

• DHA and ARA are FDA-approved and widely used.
• Plant-based sources are allergen-free.
• Consult your pediatrician for personalized advice.

Choosing the right formula for your baby is one of the most important decisions you’ll make as a parent. DHA and ARA are proven to support brain and eye development, making them essential ingredients to look for. Whether you prefer organic grass-fed options or gentle goat milk formulas, Bubs offers a range of products enriched with these vital nutrients.
