What makes a great Plant-Based Formula for Babies: Sprout Organic vs American Soy Formula

In the US, soy-based formulas have been around since the 1920’s and are so mainstream that they currently account for about 20-25% of the US formula market. Their popularity grew because of a demand for lactose free options for babies who could not tolerate cow’s milk protein.

The soy formula category in the U.S. is dominated by a small number of large brands, which means most products share very similar ingredient profiles. The dominant players like Abbott (Similac) and Mead Johnson (Enfamil) lead the category, followed by smaller players such as Gerber (Nestle) and niche brands like Earth’s Best collectively accounting for over 95% of the soy formula market.

These legacy giants ensure that the plant-based formula market offers limited variation in ingredient composition. The market is dominated by these conglomerates due to distribution (WIC contracts), brand awareness and multi-million dollar marketing budgets within long-standing regulatory frameworks that can slow the introduction of new ingredient innovations.

In the U.S., soy remains the only widely available plant-based infant formula protein for babies under 12 months. Access to plant-based proteins like rice and pea are only available online at websites such as Grow Organic Baby.

Why More Parents Are Choosing Plant-Based Infant Formula

There are 4 key drivers underpinning the growth in demand for plant-based infant formula;

1. Surging Vegan and Flexitarian Parenting Trends - A 2025 survey by the Plant-Based Foods Association found that 34% of millennial parents in the United States actively sought plant-based options for their children's first foods, including infant formula.
2. Increasing Prevalence of Cow Milk Protein Allergy and Lactose Intolerance - CMPA affects between 2% and 7.5% of infants in their first year of life, making it the most common food allergy in early childhood and necessitating complete dietary elimination of bovine dairy proteins.
3. Nutritional Innovation - Breakthroughs in ingredients, bioavailability and nutritional completeness due to improved production techniques
4. Ecommerce Expansion - offering global access to specialty formulas that were previously available only locally

Why parents should seek Plant-Based Infant Formulas Without Soy, Corn Syrup, or Palm Oil.

Most major soy-based infant formulas available in the U.S. contain ingredients that some parents may prefer to avoid.

Soy

While soy is a common dairy alternative, it raises concerns for some parents and medicall professionals due to:

• Phytoestrogens (plant compounds that mimic estrogen) which has raised questions about potential hormonal effects
• Allergenicity (soy is a top 8 allergen)
• Digestive discomfort in sensitive infants

It’s important to note that soy-based formulas are considered nutritionally adequate and safe for most healthy infants, but they are typically recommended in specific situations rather than as a first-line option.”

Corn Syrup

A commonly used ingredient in US formula as it is cheap and easy to manufacture. While corn syrup is not formally banned in Europe or Australia, infant formula regulations effectively limit the use of corn‑based sugars as primary carbohydrate sources. The main reason that some parents avoid corn syrup in infant formula:

• Has been associated in some studies with a higher risk of obesity later in childhood
• Is a processed carbohydrate that may lead to fluctuations in blood sugar levels
• Affects the gut microbiome that leads to stronger preference for sweet tastes and“fussier” eating patterns later in life

Palm Oil

Palm oil is widely used in infant formulas because it helps replicate the fatty acid profile of breast milk, however it has raised concerns among some parents for the following reasons:

• Palm oil can reduce how much calcium a baby absorbs, because it binds to calcium in the gut and prevents it from being used by the body.
• Causes constipation, discomfort and fussiness due to the build up of calcium -fat “soaps” in the gut
• Palm oil production is linked to environmental concerns due to deforestation, habitat destruction (e.g. orangutans) and increased carbon emissions

Many soy-based formulas are not vegan-certified, as they may include animal-derived ingredients such as lanolin-derived vitamin D3

For parents looking for a plant-based option that avoids soy, corn syrup, and palm oil, newer alternatives have emerged with a different ingredient approach. One example is Sprout Organic Infant Formula, which is designed to offer a fully plant-based formulation without these commonly debated ingredients.

How Does Sprout Compare to Leading Soy Based Formulas?

Unlike traditional soy formulas, Sprout uses a blend of plant proteins and a cleaner carbohydrate and oil profile designed to more closely align with modern ingredient preferences.

Conclusion

When comparing plant-based infant formulas, it’s important to look beyond marketing claims and carefully review ingredient composition. For some parents, this means choosing options that avoid soy, corn-based sugars, and palm oil, while supporting a fully plant-based formulation

Newer alternatives like Sprout Organic Infant Formula reflect this shift toward cleaner ingredient profiles, offering parents more choice in how they approach plant-based infant nutrition.
