Is Enfamil ProSobee Actually Vegan?
Enfamil ProSobee is plant-based and dairy-free, but it is not certified vegan.
It uses soy protein isolate and does not carry independent vegan certification. For many families, that’s perfectly acceptable. For others — especially those following strict vegan or organic standards — certification matters.
Sprout Organic, by contrast, is both certified vegan and certified organic, which is why it’s often chosen by families prioritizing ingredient sourcing and ethical certifications.
Soy Protein vs Pea + Rice Protein
Soy Protein Isolate (Enfamil ProSobee)
Soy has been used in infant formula for decades and provides a complete amino acid profile. Soy-based formulas are approved for use in the US and may be recommended in specific situations.
However, soy is also a known allergen for some infants. The American Academy of Pediatrics notes that soy formulas have limited indications and are not appropriate for all babies.

Rice + Pea Blend (Sprout Organic)
Sprout Organic uses complementary pea and rice proteins. When combined and formulated to infant formula standards, these proteins provide a complete amino acid profile.
This approach is often chosen by families who want to avoid both dairy and soy.
