What Is DHA in Formula and Is It Safe?

The Short Answer

DHA is an essential omega-3 fatty acid that is crucial for your baby’s brain and eye development. Because it is naturally found in breast milk, formula manufacturers add it to their recipes to make them Closest To Breast Milk.

While DHA itself is completely safe and beneficial, the way it is extracted is highly controversial. Many popular formulas use DHA sourced from lab-grown algae that is extracted using hexane—a harsh, petroleum-based solvent.

Why This Matters

Formula companies want to replicate the nutritional profile of human milk as closely as possible. Since breast milk is naturally rich in essential fatty acids, adding DHA and ARA has become the industry standard. In the EU, adding DHA to infant formula is actually legally required.

The problem isn't the nutrient itself, but the manufacturing process used to get it. To extract DHA from algae, most manufacturers use hexane, a known neurotoxin. While the FDA claims no detectable trace of hexane remains in the final powder, many health-conscious parents are extremely uncomfortable with the process. Hexane Extracted Dha

Furthermore, the specific types of algae and fungus used to create these oils have been linked to severe gastrointestinal distress in some infants. Organizations like the Cornucopia Institute have tracked thousands of reports from parents claiming these specific DHA additives cause severe diarrhea, vomiting, and gas. Best Formula Gassy Babies

What's Actually In Formula DHA Additives

When you look at a formula ingredient list, you won't just see "DHA." You will likely see these specific ingredients: Dha Source Formula

• C. cohnii oil — A lab-grown algae used as a vegetarian source of DHA. It is typically extracted using hexane and is the primary source of DHA in most commercial formulas.
• M. alpina oil — A soil fungus used to produce ARA (arachidonic acid), an omega-6 fatty acid almost always paired with DHA. It is also usually extracted using hexane.
• Hexane — A petroleum-based chemical solvent used to pull the oils out of the algae and fungus. While removed through evaporation, some consumer advocacy groups argue trace amounts could remain.
• Egg phospholipids — A cleaner, solvent-free source of DHA used by some premium brands to bypass the lab-grown algae entirely.

What to Look For

Green Flags:

• Water-extracted DHA — Brands that use water instead of harsh chemical solvents to extract their oils.
• Egg yolk sourcing — Formulas that derive their DHA from egg phospholipids naturally avoid the hexane extraction process entirely.

Red Flags:

• C. cohnii and M. alpina oils — If your baby has severe, unexplained gas or diarrhea, these specific lab-grown oils might be the culprit.
• Lack of transparency — If a brand won't disclose how they extract their DHA on their website, it's safest to assume they use hexane.

The Best Options

If you want to avoid hexane-extracted oils, you have to look for brands that prioritize clean sourcing. Here are the best solvent-free options on the market.

The Bottom Line

1. DHA is essential. Your baby absolutely needs this omega-3 for optimal brain and eye development.

2. Extraction matters. If you want to avoid petroleum-based solvents, look for brands that use water-extracted DHA.

3. Watch your baby's tummy. If your infant is experiencing severe gas or diarrhea, the C. cohnii oil in their formula might be the trigger.

FAQ

Does organic formula use hexane-extracted DHA?

Yes, many organic formulas still use hexane-extracted oils. The USDA organic standards require a product to be 95% organic, which leaves a 5% window for non-organic additives like C. cohnii oil. You have to check the specific brand's extraction methods. Best Organic Formula

Is baby formula with DHA regulated by the FDA?

Yes, but the FDA considers these oils "Generally Recognized as Safe" (GRAS). While the FDA recently issued new guidance in 2024 and 2025 regarding infant formula safety, they do not currently restrict the use of hexane in DHA extraction. Is Formula Fda Regulated

Should I switch formulas if mine has C. cohnii oil?

Only if your baby is having digestive issues. The vast majority of infants tolerate these standard DHA additives perfectly fine. If your baby is happy and growing, there is no need to panic-switch.
