A 2026 study of 120 Chinese infants found that a specially designed infant formula with whey protein and breast milk components supported digestion and immune health similarly to breast milk. Babies fed the formula had comparable digestive comfort scores (19.9 vs 16.8), similar beneficial gut bacteria levels, and matching immune markers after 6 weeks, suggesting this formula is an effective option for families who cannot breastfeed.
Researchers tested a special infant formula designed to copy breast milk’s healthy components in Chinese babies. The formula contained whey protein and other ingredients found naturally in breast milk. After 6 weeks, babies fed this formula had just as good digestion, healthy gut bacteria, and immune markers as breastfed babies. The study included 60 formula-fed and 60 breastfed infants, making it one of the first to show this particular formula works similarly to breast milk for supporting baby health.
Key Statistics
A 2026 research article published in BMC Nutrition involving 120 Chinese infants found that babies fed a whey protein-enriched formula had digestive comfort scores of 19.9 compared to 16.8 in breastfed babies, a difference of only 1.35 points that was not statistically significant.
According to a 2026 study of 60 formula-fed and 60 breastfed Chinese infants, the formula-fed group had significantly higher levels of beneficial short-chain fatty acids (valeric and propanoic acids) in their stool compared to breastfed babies, supporting intestinal health.
A 2026 research article found that Bifidobacterium abundance (beneficial gut bacteria) was not significantly different between 60 infants fed a special whey protein formula and 60 breastfed infants after 6 weeks, indicating the formula supported healthy gut colonization similarly to breast milk.
In a 2026 study of 120 Chinese infants, immune markers, inflammation indicators, and intestinal barrier integrity were similar between formula-fed and breastfed groups at 6 weeks, with no significant differences in growth, illness rates, or adverse events between groups.
The Quick Take
- What they studied: Whether a specially designed infant formula with ingredients from breast milk could help babies digest food well and develop healthy immune systems just like breastfed babies do.
- Who participated: 120 Chinese infants between 3 and 28 days old—60 who were formula-fed and 60 who were breastfed. Researchers followed them for 6 weeks.
- Key finding: Babies fed the special formula had similar digestion comfort scores (19.9 vs 16.8 on a health scale) and comparable gut bacteria and immune markers to breastfed babies, showing the formula worked nearly as well as breast milk.
- What it means for you: If you’re formula-feeding your baby, this formula may support your infant’s digestion and immune health similarly to breastfeeding. However, breast milk remains the gold standard, and this formula is one option among many—talk to your pediatrician about what’s best for your baby.
The Research Details
This was a single-arm prospective intervention study, meaning researchers followed one group of babies over time and measured what happened. Researchers enrolled newborns between 3 and 28 days old and divided them into two groups based on how they were already being fed: formula-fed (60 babies) or breastfed (60 babies). The formula-fed group received a special infant formula enriched with whey protein concentrate, alpha-lactalbumin, milk fat globule membrane (MFGM), and Sn-2 palmitate—all components naturally found in breast milk.
Over 6 weeks, researchers measured how well babies tolerated feeding using a questionnaire called the Infant Gastrointestinal Symptom Questionnaire (IGSQ). They also collected stool samples to analyze gut bacteria using advanced genetic sequencing, measured immune markers and inflammation indicators, tracked stool consistency, monitored growth, and recorded any health problems or medications used.
This approach allowed researchers to compare real-world feeding outcomes between babies getting the special formula and those receiving breast milk, providing practical evidence about how well the formula supports infant health.
Understanding whether formula can match breast milk’s benefits is important because not all mothers can breastfeed. If a formula can provide similar immune support and digestive health, it gives families more options while ensuring babies still get important health benefits. This study used advanced laboratory techniques to measure actual immune and gut health markers rather than just asking parents about symptoms, making the evidence stronger.
The study’s strengths include using validated questionnaires, advanced laboratory methods (genetic sequencing and mass spectrometry) to measure gut bacteria and immune markers, and careful tracking of multiple health outcomes. The main limitation is that it was not a randomized controlled trial—babies were assigned to groups based on their existing feeding method rather than randomly assigned, which could introduce bias. The study was also conducted in China with Chinese infants, so results may not apply equally to other populations. Additionally, 6 weeks is a relatively short follow-up period, so long-term effects remain unknown.
What the Results Show
The main finding was that babies fed the special formula had good digestion tolerance that was not significantly different from breastfed babies. The formula-fed group had an average IGSQ score of 19.9 (lower scores indicate better tolerance), while the breastfed group scored 16.8—a difference of only 1.35 points that was not statistically significant, meaning it could easily be due to chance.
When researchers examined gut bacteria, they found that Bifidobacterium (a beneficial bacteria associated with healthy digestion) was present in similar amounts in both groups. This is important because breast milk naturally promotes these good bacteria, and the formula appeared to do the same.
Interestingly, babies fed the formula had higher levels of short-chain fatty acids (SCFAs)—beneficial compounds produced when good bacteria break down food. Specifically, valeric and propanoic acids were significantly higher in the formula-fed group. These compounds support gut health and immune function.
Other markers of immune health, inflammation, intestinal barrier integrity, stool consistency, growth measurements, and rates of common illnesses were similar between groups. Babies in both groups had similar rates of antibiotic use and adverse events.
One notable secondary finding was that lipocalin-2 (a marker of intestinal stress) was significantly higher in breastfed babies compared to formula-fed babies, suggesting the formula may have caused slightly less intestinal stress. However, this single marker difference was small and didn’t translate to any clinical differences in symptoms or health outcomes. Quality of life scores and growth measurements (weight and length) were comparable between groups, indicating both feeding methods supported normal infant development.
This study builds on previous research showing that adding breast milk components to formula can improve infant health outcomes. Earlier studies suggested that whey protein, MFGM, and palmitate (the ingredients in this formula) individually support digestion and immune function. This research is among the first to test a formula combining all these ingredients together and to measure actual immune markers and gut bacteria in Chinese infants. The findings align with other research suggesting that well-designed formulas can approximate some—though not all—of breast milk’s benefits.
The study has several important limitations. First, it was not randomized, meaning babies weren’t randomly assigned to formula or breast milk groups—they were assigned based on their existing feeding method. This could introduce bias because families who choose to breastfeed may differ in other ways from families who formula-feed. Second, the study only lasted 6 weeks, which is relatively short for assessing long-term health effects. Third, the study was conducted in China with Chinese infants, so results may not apply equally to other ethnic groups or populations. Fourth, the study didn’t include a control group receiving standard formula without the special ingredients, so we can’t definitively say the added ingredients caused the benefits. Finally, the sample size of 60 per group is moderate, so some real differences might not have been detected.
The Bottom Line
According to Gram Research analysis, this formula appears to be an effective option for formula-feeding families, supporting digestion and immune health similarly to breast milk in the short term (moderate confidence level). If you’re formula-feeding, discuss this formula option with your pediatrician to determine if it’s appropriate for your baby. Breast milk remains the recommended first choice when possible, but this formula may be a good alternative when breastfeeding isn’t an option (high confidence level).
This research is most relevant to parents and caregivers who are formula-feeding infants or considering formula-feeding. Pediatricians and infant nutrition specialists should be aware of this formula option when counseling families. Parents who are breastfeeding don’t need to change anything based on this research. Families with specific concerns about their baby’s digestion or immune health should consult their pediatrician before making feeding changes.
Based on this study, you could expect to see benefits in digestion and stool consistency within 2-4 weeks of starting the formula. However, immune system benefits and changes in gut bacteria may take the full 6 weeks to become apparent. Long-term benefits beyond 6 weeks are unknown and would require additional research.
