Sprout Organic vs Préminat (Prémiriz): Vegan Baby Formula Comparison 2026

If you've been researching vegan baby formula, you've probably come across two names: Sprout Organic and Préminat (formerly known as Prémiriz). Both are organic, dairy-free, soy-free, and made entirely from plant-based ingredients. Both are designed to provide complete infant nutrition without animal-derived components.

But there's a catch — and it's a big one for US parents.

Préminat has become increasingly difficult to source in the United States. Stock is limited, availability is unpredictable, and many retailers — including The Milky Box — have seen supply dry up. Sprout Organic, on the other hand, remains consistently available and ships to US families with reliable, tracked delivery.

This guide compares both formulas on ingredients, protein, nutrition, certifications, and practical availability — so you can make an informed decision even when one option is hard to find.

Préminat Riz — previously sold under the name Prémiriz — is a French organic infant formula made by Prémibio, a brand within the La Mandorle family of companies. It was one of the first hydrolyzed rice protein formulas developed specifically for infants, launching originally in 2015 and earning a Gold Innovation Trophy upon release.

The formula was designed primarily for babies with cow's milk protein allergy (CMPA), lactose intolerance, or other digestive sensitivities. It uses enzymatically hydrolyzed rice protein, meaning the protein is broken into smaller peptides for easier digestion and reduced allergenic potential.

Préminat covers a wide age range — 0 to 36 months — in a single formulation with no stage switching. This was one of its key selling points for parents who wanted a consistent formula from birth through toddlerhood.

The rebrand from Prémiriz to Préminat is a name change only — the formula composition remains the same.

Both formulas are dairy-free, soy-free, gluten-free, and palm oil-free. But they differ significantly in protein technology, origin, staging, and — most critically — availability

Sprout Organic

Préminat (Formerly Prémiriz)

This is the biggest formulation difference between the two

Sprout Organic: Intact Pea + Rice Blend

Sprout uses a blend of organic pea protein and organic rice protein in their whole, intact form. These two proteins are complementary — pea is rich in lysine, rice provides methionine — and together they deliver a complete amino acid profile that meets infant nutrition standards.

Intact proteins have not been broken down, which means a milder taste and smoother texture compared to hydrolyzed alternatives.

Préminat: Hydrolyzed Rice Protein 

Préminat uses rice protein that has been enzymatically hydrolyzed — broken into smaller peptides to reduce allergenic potential and support easier digestion. Because rice protein alone is low in certain amino acids (lysine and tryptophan), Preminat adds free amino acids to complete the profile.

Hydrolyzed rice protein formulas have clinical evidence supporting their use in babies with confirmed CMPA. A review published in the Journal of Clinical Medicine concluded that hydrolyzed rice formulas are tolerated by over 90% of infants with proven cow's milk allergy.

The takeaway: Préminat's hydrolyzed protein was designed specifically for allergy management under medical guidance. Sprout Organic's intact protein blend is designed for general plant-based feeding — gentler tasting, simpler to prepare, and suitable for families choosing a vegan formula without a specific allergy diagnosis.

Carbohydrates  

Neither formula uses corn syrup solids, lactose, or added sugars. For more on what to look for in formula ingredients, see our guide to what makes up a good baby formula.

Oil and Fats 

Both formulas avoid palm oil entirely. Both include Algal DHA (omega-3 from microalgae, not fish oil) for brain and eye development. Préminat also includes ARA from Mortierella alpina oil.

Vitamin D

Both formulas source Vitamin D from plants — not from lanolin (sheep's wool), which is the standard in most mainstream formulas. Préminat specifically uses Vitamin D from lichen. This matters for strictly vegan families.

Vitamins & Mineral

Both formulas include the full spectrum of micronutrients required by their respective regulatory frameworks. Sprout Organic is validated against the FSANZ infant formula standard. Préminat complies with EU infant formula regulations. Préminat also highlights its use of natural calcium from Lithothamnium (a marine algae) and natural marine magnesium.

This is where the two formulas take fundamentally different approaches.

Préminat: One formula. 0-36 months

Preminat's single-formula model means no stage switching at all. The same product is used from birth through toddlerhood. For parents who value simplicity and want to avoid the complexity of transitioning between formula stages, this is appealing.

However, a single formulation covering 0–36 months also means the nutrient profile is a compromise — optimized broadly rather than tailored to the specific developmental needs of each age window.

Sprout Organic

A two-stage system allows for more precise nutrient targeting at each developmental phase. For guidance on when to transition between stages, see our toddler formula ultimate guide.

Sprout Organic

Préminat 

The FSMP classification means Préminat was positioned in Europe as a medical-grade formula for babies whose dietary needs cannot be met by standard products. This doesn't make it inherently "better" — it means it was designed for a specific clinical use case, particularly babies with CMPA or lactose intolerance.

Sprout Organic's independent vegan certification is a distinction worth noting. While Préminat is formulated entirely from plant ingredients, it does not carry a separate third-party vegan certification in the way Sprout does.
