65% of U.S. Parents Surveyed Think "Human Milk Fortifier" Contains Donor Human Milk; Yet Only One Does

New survey finds even parents whose babies spent time in the NICU are confused about what premature infants are fed

DUARTE, Calif., Nov. 12, 2026 /PRNewswire/ -- A new national survey released for Prematurity Awareness Month by Prolacta Bioscience finds widespread confusion among parents about a vital nutritional product often given to premature babies in the neonatal intensive care unit (NICU). The product is labeled "Human Milk Fortifier." Two in three U.S. parents (65%) think the name means it contains donor breastmilk. In fact, every human milk fortifier used in the U.S. is made from cow milk, except for one.

The confusion starts with the label itself. "Human Milk Fortifier" was originally intended to describe what the product is added to, not what it's made from. Many parents don't realize there are two types of these fortifiers, one made from donor breastmilk and all the others made from cow milk. Even parents whose babies spent time in the NICU are confused: 66% think human milk fortifiers contain donor breastmilk, and only 7% knew it is typically made from cow milk.

Premature babies, especially those born weighing 2.75 pounds or less, need more calories, protein, and nutrients than breastmilk alone can provide. To help them grow, doctors often add a fortifier to their milk. Studies over the past 20 years link a diet made entirely from human milk, including a fortifier made from donor breastmilk, with fewer complications of prematurity and better long-term development.^1-7 Prolacta Bioscience, which commissioned the survey, makes the only human milk fortifier in the U.S. made from donor breastmilk, free from cow milk. More than half of Level III and IV NICUs in the U.S. used Prolacta fortifiers in 2026.⁸ 

Almost all parents surveyed (95%) said a short list of feeding questions would be useful, rising to 98% among parents whose baby spent time in the NICU. To help parents ask key questions during their NICU journey, Prolacta has created a free guide parents can use with their NICU care team, available at parents.prolacta.com. Other survey findings:

• Nearly half of parents surveyed (48%) would not have known, or were unsure, whether to ask if their premature baby's added nutrition was made from cow milk or donor breastmilk.
• 70% of NICU parents said they would know what to ask about a premature baby's feeding needs, yet only 7% knew human milk fortifier is typically made from cow milk.
• 93% said it would be important for a premature baby to reach the same developmental milestones as a baby born full term.

Early NICU Nutrition Shapes Long-Term Development

Since a premature baby's brain is growing so quickly, the nutrition they receive in their first weeks of life can shape their long-term development.^9-11 A 2025 study of more than 1,000 infants across 13 Southern California NICUs found that preemies who received Prolacta's fortifiers as part of an exclusive human milk diet (EHMD) were significantly less likely to have motor skill delays at age 3.² These motor skills help toddlers walk, run, climb, and explore their world, in step with other children their same age. A separate study conducted in 2022 found that babies fed an EHMD had significantly higher cognitive scores (thinking, learning, attention) at 18 to 22 months corrected age than babies fed cow milk-based products.³ 

In December of 2025, Japan approved Prolacta's fortifiers as prescription drugs, a world first in neonatal nutritional care, following the successful completion of a Phase III clinical trial in Japan.¹ Given Japan's longstanding leadership role in advancing neonatal care globally, this drug designation affirms Prolacta's rigorous quality and safety standards, a level of assurance that matters to U.S. parents, too. In the survey, 87% of U.S. parents said they would want their premature baby to have access to a donor breastmilk-based product that met the quality standards required for prescription medicine.

"An early birth can introduce nutrition decisions families never expected to face," said Melinda Elliott, MD, FAAP, neonatologist and chief medical officer at Prolacta. "Parents deserve clear, plain-language information about the nutritional fortifier their baby receives, the evidence behind the available options, and the questions they can discuss with their NICU care team. One of the most important questions is simple: Is my baby's fortifier made from cow milk or human milk?"

Frequently Asked Questions

Who was surveyed?
Prolacta commissioned OnePoll to conduct the online survey of 1,000 U.S. parents whose first child is age 4 or younger, including 125 parents whose child spent time in the NICU. The survey was fielded October 13-21, 2026, and included parents across the Midwest, Northeast, Southeast, Southwest, and West.

Where can I find a list of feeding questions to discuss with my baby's care team?
Prolacta has developed a free guide to help parents understand the nutritional needs of premature infants and discuss feeding options with their NICU team.

Where can I learn more?
