Enfamil
ProSobee
Our verdict
A dependable, decades-proven soy formula for the specific situations that call for one — galactosemia, congenital lactase deficiency, or a family commitment to plant-based feeding. It is not a fussiness fix or an allergy answer, and its recipe is mostly corn syrup solids plus palm oil. Right tool, narrow job; involve your pediatrician in the decision.
Score breakdown

- Multiple forms (powder, concentrate, ready-to-use)
Worth knowing
- Primary carbohydrate is corn syrup solids (~54% of powder ingredients)
- Contains palm olein oil

Note: AAP guidance (verified via AAP clinical report 'Use of Soy Protein-Based Formulas in Infant Feeding' and HealthyChildren.org): soy formula is indicated for galactosemia and hereditary/congenital lactase deficiency, and is acceptable for families preferring a vegan/plant-based diet; it is NOT recommended for routine management of colic or as first choice for cow milk protein allergy (10-14% of milk-allergic infants also react to soy; extensively hydrolyzed formula is preferred there). Powder composition per retailer listing: corn syrup solids ~54%, vegetable oil ~26%, soy protein isolate ~14%. Price basis: Walmart lists the 20.9 oz powder at ~$1.86/oz (~$38.87/can). Verified ASIN B0845FVDLH is the 32 fl oz ready-to-use bottle 4-count listing (seen in an amazon.com/dp URL); powder listings also exist on Amazon but no powder /dp/ URL was directly observed in search results.

- Taste/smell called mild by some parents ('similar to regular milk')
- Reliable availability at big-box stores and via WIC
Common complaints
- Constipation and firmer stools are the most common complaint (a published stool-pattern study also found firmer stools with ProSobee)
- Some parents dislike the smell (described by some as metallic)
- Green stools reported (common with higher-iron soy formulas)
- Some babies refuse the taste
Common questions
When is soy formula actually recommended?
The American Academy of Pediatrics limits routine soy formula use to specific situations: galactosemia, hereditary lactase deficiency, and families preferring a vegan diet. It is not recommended for colic, and not first-line for milk allergy (10–14% of milk-allergic babies also react to soy).
Does ProSobee help with milk allergy?
Usually not the right choice — a significant minority of milk-allergic infants react to soy protein too. Extensively hydrolyzed formulas (Nutramigen, Alimentum) are the standard path, chosen with a pediatrician.
Why are my baby's stools different on ProSobee?
Firmer stools (sometimes constipation) and a green tint are commonly reported and well documented with soy formulas — generally considered normal for the category, but flag persistent discomfort to your pediatrician.
