Nutramigen vs. Alimentum: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on February 29, 2024
Nutramigen and Alimentum are both hypoallergenic infant formulas designed for babies with milk allergies, but they differ in brand and formulation specifics.

Key Differences

Nutramigen is a hypoallergenic infant formula produced by Enfamil, designed for babies with allergies to cow's milk. It uses extensively hydrolyzed proteins to reduce allergenicity. Alimentum is a similar hypoallergenic formula made by Similac, also using hydrolyzed protein, but with different additional ingredients and formulation.
Both Nutramigen and Alimentum are intended to provide complete nutrition for infants unable to tolerate regular formula. Nutramigen includes LGG, a probiotic meant to help with gut health, whereas Alimentum does not specifically include this probiotic.
Nutramigen is often recommended for infants with colic symptoms related to cow's milk allergy. Its formula aims to reduce colic symptoms within 48 hours. Alimentum also claims to reduce colic symptoms due to protein sensitivity, but the time frame for relief may vary.
In terms of taste and digestibility, some parents report differences. Nutramigen might have a distinct taste due to its composition, which can affect some babies' acceptance. Alimentum has its unique formulation, which might be more palatable for some infants.
The cost can vary between Nutramigen and Alimentum, with prices fluctuating based on location and retailer. Parents may choose between them based on cost-effectiveness, availability, or pediatrician recommendation.
