Background and Objectives: Observational studies suggest differences between breast-fed and formula-fed infants in developmental myelination, a key brain process for learning. The study aims to investigate the efficacy of a blend of docosahexaenoic acid (DHA), arachidonic acid (ARA), iron, vitamin B12, folic acid, and sphingomyelin (SM) from a uniquely processed whey protein concentrate enriched in alpha-lactalbumin and phospholipids compared with a control formulation on myelination, cognitive, and behavioral development in the first 6 months of life.

Methods: These are 6-month results from an ongoing two-center, randomized controlled trial with a 12-month intervention period (completed for all participants). In this study, full term, neurotypical infants of both sexes (N = 81) were randomized into investigational (N = 42) or control groups (N = 39). In addition, non-randomized breast-fed children (N = 108) serve as a natural reference group. Main outcomes are myelination (MRI), cognitive (Bayley Scales of Infant and Toddler Development, 3rd edition [Bayley-III]), social-emotional development (Ages and Stages Questionnaires: Social-Emotional, 2nd edition [ASQ:SE-2]), sleep (Brief Infant Sleep Questionnaire [BISQ]), and safety (growth and adverse events [AEs]).

Results: The full analyses set comprises N = 66 infants. Significant differences in myelin structure, volume, and rate of myelination were observed in favor of the investigational myelin blend at 3 and 6 months of life. Effects were demonstrated for whole brain myelin and for cerebellar, parietal, occipital, and temporal regions, known to be functionally involved in sensory, motor, and language skills. No statistically significant differences were found for early behavior and cognition scores.

Conclusions: This is the first study demonstrating the efficacy of a myelin nutrient blend in well-nourished, term infants on developmental myelination, which may be foundational for later cognitive and learning outcomes.

Clinical Trial Registration:, identifier: NCT03111927.


Myelination is a cornerstone of human neurodevelopment ensuring coordinated communication between brain cells and networks (1, 2). It has been positively associated with cognitive ability throughout postnatal development (~6.5–16 months) as well as in children and adults (35), making it an important research target for strategies that support brain, cognitive, and learning development.

Brain development is particularly rapid in the first years of life and requires nurturing care, such as nutrition (6, 7). Nutritional deficiencies, such as iron, vitamin B12, and folate, have been associated with hypomyelination, altered myelin composition, or decreased myelin synthesis (810). Observational studies suggest early life differences between formula-fed and breast-fed infants in fatty acid-related white matter (WM) composition (11) as well as in myelination and cognitive abilities, possibly linked to long-chain polyunsaturated fatty acids (LC-PUFA), sphingomyelin (SM), iron, and folic acid levels in infant nutrition (12, 13).

No intervention study has yet investigated the effects of nutritional supplementation on developmental (i.e., de novo) myelination. A pilot randomized clinical trial in low-birth-weight infants showed increased SM plasma and erythrocyte levels at 4, 6, and 8 weeks of life as well as improved scores in the behavior and attention measures at 18 months, following intervention with SM-fortified infant formula (20 vs. 13% of total milk phospholipids) in the first weeks of life (14). Myelination improvements were speculated by the authors as a potential mechanism.

A study in rodents using a diet containing different concentrations of docosahexaenoic acid (DHA) reported effects on myelin composition and function in pups in a concentration dependent manner (15). Similarly, we previously demonstrated that in vitro treatment with a blend of DHA, arachidonic acid (ARA), vitamin B12, folic acid, iron, and SM in a primary cell culture model increased the number of oligodendrocyte precursor cells, their differentiation, and maturation. These effects were dose-dependent with only higher doses of the blend showing significant effects. Furthermore, the data suggest a specific mechanistic impact of the individual nutrients and an interaction effect between the investigated nutrients with a positive net effect for the blend that was not observed for the individual compounds (16).

While available findings support the impact of nutrients on developmental myelination, their efficacy in term-born human infants has not been investigated. We conducted a two-center, double-blind, randomized controlled investigational trial in neurotypical term-born children to compare the effect of a nutrient blend containing DHA, ARA, iron, folic acid, vitamin B12, and SM (from a uniquely processed whey protein concentrate enriched in alpha-lactalbumin and phospholipids) in the first year of life to test the main hypotheses that higher levels of the nutrient blend increase myelin in the developing brain.

Materials and Methods

Trial Design

The study has a prospective, longitudinal, two-center (Memorial Hospital of Rhode Island and Pennington Biomedical Research Center, USA), double-blind, randomized, controlled, parallel group design with a 12-month intervention period and follow-up assessments up to 2 years of life. Five visits occur during the intervention period [V1 (6 ± 1 week of life), V2 (3 months ± 2 weeks), V3 (6 months ± 2 weeks), V4 (9 months ± 2 weeks), and V5 (12 months ± 2 weeks)]; two visits during the follow-up period [V6 (18 months ± 3 weeks), V7 (24 months ± 4 weeks)]. The follow-up visits are still ongoing while the 12-month intervention period has closed for all enrolled children. The reported findings refer to the staged statistical analysis of the 3- and 6-month time points.

Trial Participants and Recruitment

Recruitment occurred between May 2017 and March 2020 via self-referral by one or more of the following: (1) local advertisements on social and general media, (2) information flyers and posters provided to community groups, and (3) information brochures given to women identified through or attending relevant hospital clinics.

Maternal screenings were performed during the third trimester of pregnancy up to and including post-delivery. Infants' enrollment window was between 2 and 5 weeks of life for formula-fed infants and breast-fed infants were enrolled earlier. Following written informed consent (screening visit), sociodemographic information, medical and family histories were collected, as well as a physical and neurological examination of the infant. Withdrawal from the study was possible at any point and with no further evaluations and any additional data collection. The research ethic boards at both clinical sites approved the protocol.

Randomization and Blinding

Eligible non-breast-fed infants were randomized at V0 (baseline) into the investigational or control group with a 1:1 allocation using a permuted block randomization stratified by site and gender. Block size was not disclosed in the protocol to ensure the unpredictability of the randomization sequence. Investigational and control products were blinded by the manufacturer with non-speaking codes. Investigators, staff performing the assessments, and data analysts remain blind to the individual group allocation until the study database will be locked and the Statistical Analysis Plan (SAP) signed. To perform the statistical analysis of the data up to 6 months of age, a collaborator at the clinical site and an external contract research organization were unblinded. For the staged statistical analyses, only aggregated information was shared with the sponsor to ensure blinding until trial completion. Breast-fed children were not randomized.

Trial Interventions

Intervention products were bovine milk-based infant formulas manufactured by Wyeth Nutrition, Askeaton, Ireland. The alpha-lactalbumin enriched whey protein concentrate used for the control product was almost devoid of phospholipids and SM, while the alpha-lactalbumin enriched whey protein concentrate used in the investigational product contained higher levels of SM and phospholipids due to the unique manufacturing process of ingredients. The investigational product contained higher levels of DHA, ARA, iron (fortified through ferrous sulfate heptahydrate), folic acid, and vitamin B12 (fortified through cyanocobalamine) (Table 1) than the control product. The higher levels were based on observational data and adjusted based on regulatory requirements for infant nutrition products. Nutrients were selected based on their reported presence in breast milk, use in infant formulas, and, in most cases, are mandated for inclusion as individual compounds in routine use infant formulas for healthy infants.


Table 1. Nutrient levels in intervention products* and breast milk.

Both blends were provided in an infant formula matrix and taken orally from enrollment to 12 months of life based on a response-feeding approach. Both intervention products included the same organoleptic and sensory characteristics to secure blinding. The investigational product contained the above described uniquely processed whey protein concentrate while the control product contained a standard whey protein concentrate.

The sponsor adheres to the WHO Code supporting exclusive breast-feeding for at least the first 6 months of life. The study team did not influence the parental feeding choice at any time. A lactation consultant was freely available to support and advise mothers regarding lactation.

Trial Outcomes

The main outcomes for the staged statistical analyses were myelination measures derived from MRI at V2 (3 months) and V3 (6 months) following MRI acquisition and analyses applied in previous pediatric studies (2, 12, 17): myelin water fraction (MWF) for myelin volume (mcDESPOT) and T1 and T2 images for myelin structure (MP-RAGE).

Additional outcomes included overall cognitive development as assessed by the Bayley Scales of Infant and Toddler Development, 3rd edition (Bayley-III) (18) at V3 (6 months), social-emotional development as assessed by parent-report via Ages and Stages Questionnaires: Social-Emotional, 2nd edition (ASQ-SE:2) (19) at V2 (3 months) and V3 (6 months), brain volumetric outcomes as assessed by structural MRI (MP-RAGE) at V2 (3 months) and V3 (6 months), and infant sleep [Brief Infant Sleep Questionnaire (BISQ) (20)]. Descriptive measures included adverse events (AEs) and safety assessments.

Data and Biological Sample Collection

Study data were collected by the trained research staff using an access-controlled, web-based database (electronic Case Report Form (eCRF), Medidata) within 7 days of each participant's visit. No personal information was stored in the study database but separately at each institution with access limited to study coordinators. The clinical data management systems developed for this study complied with the Good Clinical Practices (GCP) predicate rule requirements, laws, and regulations (Personal data protection) and allowed an audit of actions performed by users.

Maternal breast milk samples were collected at V0, V1, and V2 in the BF reference group. All breast milk analyses were carried out anonymously by accredited laboratories.

Safety Assessment

Parent-reported AEs and infant growth measures for weight and length were collected. Medical history, AEs, and serious adverse events were coded according to the Medical Dictionary for Regulatory Activities (MedDRA) version 16.0.

MR Imaging and Analyses

Neuroimaging was performed on a Siemens 3T Trio during natural non-sedated sleep [as shown in (21)]. mcDESPOT multicomponent relaxometry was used to derive MWF measures (22) and brain volumes for WM, gray matter (GM), cerebellum, and corpus callosum (CC). Whole brain, six a priori (cerebellum, frontal and parietal lobe, CC body, genu, and splenium), and two post-hoc (occipital and temporal lobe) WM regions of interest (ROI) were included.

Multicomponent relaxometry data were visually assessed for motion artifacts (such as blurring and ghosting) and MWF measures were estimated. The quantitative MWF images were non-linearly aligned to Montreal Neurological Institute (MNI) space using a multi-step, multi-scale approach. Brain regions with similar myelination patterns were identified by merging the 1,290 image volumes into a single 4D time-series (analogous to a functional imaging series) and using probabilistic independent component analyses (PICA) (23) to delineate the non-orthogonal but statistically independent spatial regions with shared temporal myelination trajectories in an unsupervised and data-driven manner. The number of extracted independent components (ICs) was derived from the estimate of Bayesian evidence. Previously calculated brain masks and initial WM, GM, and cerebral cerebrospinal fluid estimates were then aligned to individual anatomical data of each child and used as starting priors for the ANTs Atropos voxel-wise WM, GM, CC, and cerebellum segmentation method.

Sample Size Justification

Based on previous data (2, 12, 17), the MWF served as the lead marker for sample size justification. With a power of 80%, a sample size of n = 64 completed infants per intervention group was estimated to cover a mean MWF difference between groups ≥ 0.005 (SD = 0.010). With an estimated dropout rate of 25%, a maximum of 86 infants per intervention group was planned to be enrolled. In total, 92 infants were planned to be enrolled in the non-randomized reference group of breast-fed infants, expecting a 30% drop-out rate. Sample size calculations were performed using SAS 9.3. Due to the operational constraints encountered by the clinical sites following the coronavirus disease 2019 (COVID-19) pandemic, the recruitment was stopped at 81 infants in the randomized arms and 108 infants in the breast-fed arm.

Statistical Analysis

An SAP was developed prior to the staged statistical analysis of the 3- and 6-months data. All analyses were conducted according to the randomized assignment. Both intervention groups were compared using descriptive statistics, independent t-tests, as well as analysis of covariance (ANCOVA), corrected for stratification factors. Intercepts and slopes for longitudinal analyses were estimated using a mixed model for repeated measurements (MMRM) corrected for the chronological age of individuals. The p-values were used to indicate potentially interesting results and were not corrected for multiplicity. Endpoint distributions were evaluated, and planned analyses were adapted accordingly prior to the contract research organization unblinding.

Post-hoc analyses were performed to compare the non-randomized breast-fed reference group with the two randomized arms, providing descriptive statistics and inferential analyses conducted (superiority, two-sided) using ANCOVA corrected for the stratification factors and weighted by the estimated inverse propensity score (PS) of being breast-fed in the trial (1/PS for breast-fed infants and 1/(1-PS) for formula fed infants). The score was calculated with a logistic regression on breast-fed/not breast-fed explained by the baseline covariates maternal marital status, family income, maternal full scale IQ estimate (Wechsler Abbreviated Scale of Intelligence, 2nd edition, WASI-II), number of siblings, the highest level of education (mother, father, or any adult living with the child), the father living with the child, and maternal depression score (Edinburgh Postnatal Depression Scale, EPDS) at 6 weeks post-partum. When normality of the residues underlying the ANCOVA could not be assumed after data log-transformation, a non-parametrical Wilcoxon test was applied disregarding the propensity score.



A total of 189 infants were enrolled, of which 81 (42.9%) were randomized into the two intervention groups and 108 (57.1%) participated in the breast-feeding reference group. The mean infant age at enrollment was 29.9 (±7.45) days. Baseline characteristics were similar between intervention groups (Table 2). The full analysis set comprised 174 children (Figure 1). Reasons for premature withdrawal were evenly distributed between the randomized groups; missing data were considered as missing at random. Imaging data were available for 99 infants (56 girls) at 3 months and 71 infants (36 girls) at 6 months of age but reduced to 91 (52 girls) infants at 3 months, and 66 infants (34 girls) at 6 months of age for MWF and T1 data due to scanning complications at one of the sites (Table 3).

Children were randomized into one of two intervention groups, either receiving a blend of docosahexaenoic acid (DHA), arachidonic acid (ARA), iron, vitamin B12, folic acid, and sphingomyelin (SM) from a uniquely processed whey protein concentrate enriched in alpha-lactalbumin and phospholipids or a control formulation. Non-randomized breast-fed children served as a natural reference group.

Myelin Volume and Structure

Of the 175 ICs identified (accounting for 80% of the total variance in the dataset), 24 parcellations showed significantly (p ≤.05, equal variances assumed) larger MWF volume, 19 significantly reduced T1, and 8 parcellations significantly reduced T2 values in the investigational over the control group at 3 months (Figure 2A). Seventy-nine parcellations showed significantly larger MWF volume, 15 significantly reduced T1, and one parcellation significantly reduced T2 values in the investigational over the control group at 6 months (Figure 2B). Regarding regions, the temporal lobe MWF was statistically larger, while occipital and parietal lobe T1 values were significantly reduced for the investigational group over the control group at 3 months of age. No significant differences were found for T2 scans (Figure 2C). At 6 months, the whole brain, cerebellum, parietal, occipital, and temporal lobe MWF were statistically larger and, occipital and temporal lobe T1 values were significantly smaller in the investigational over the control group. No significant differences were detected for T2 scans (Figure 2D). Descriptive statistics are shown in Supplementary Figures S1S7.


Figure 2. Intervention group differences in myelin volume (myelin water fraction [MWF]) and structure (T1 and T2) for independent component (IC) analyses (A,B) and for segmentation, such as cerebellum, frontal, and parietal lobe, corpus callosum (CC), occipital, and temporal lobe white matter (WM) regions (C,D).

Post-hoc analyses adjusted for the described propensity score indicated no statistically significant differences between the investigational and breast-fed groups nor between control and breastfeeding groups at 3 and 6 months for MWF of the whole brain and CC (splenium, body, and genu), for T2 of the whole brain, cerebellum, parietal and frontal WM, and CC (body and genu). Statistically significant lower T1 values of the whole brain and ROIs as well as higher MWF values of the cerebellum, parietal, and frontal WM were found in the investigational compared with the breast-fed group at 3 months but not at 6 months.

Myelin Growth Rate Differences

Longitudinal modeling of MWF slopes in the ROI yielded significantly steeper slopes in CC body (p = 0.025), CC genu (p = 0.016), CC splenium (p = 0.017), in temporal (p = 0.045), parietal (p = 0.012), and occipital lobes (p = 0.0511) as well as in the whole brain (p = 0.013) for the investigational group compared with control. No significant intercept differences were found between groups. MWF regression plots with confidence bands are displayed in Figure 3 and intercept and slope estimates in Table 4.

Brain Volume, Behavior, and Safety

No significant differences were found for total WM, GM, cerebellum, and CC volume, nor for cognitive, language, motor, social-emotional development, and sleep at 3 and 6 months. Results, however, showed a statistically non-significant reduction of night awakenings at 6 months in favor of the investigational product (least square means (LSMeans): −0.8 awakenings, 95% CI [−1.84; 0.24], p = 0.1262), with a least-square mean reduction of 38.6% compared with the control group (Figure 4).

Safety findings were largely similar across groups. Body weight and length values were between 10th and 90th percentiles for most infants at 3 (weight: 84, 89.3, and 83.7%; length: 80, 78.6, and 76.7% for the investigational, control, and breast-fed group, respectively) and 6 months (weight: 78.3, 74.1, and 74.7%; length: 82.6, 70.4, and 72.0% for the investigational, control, and breast-fed group, respectively). Regarding AE, 2/34 participants in the control group, 6/32 in the investigational group, and 3/108 in the breastfeeding group were reported to have had constipation. One AE in each group was considered related to the respective study product. No serious AE was reported.


This clinical trial is the first to demonstrate the impact of a myelin nutrient blend on developmental myelination in term-born infants as early as 3 and 6 months of life.

We demonstrated increases in myelin volume in favor of the investigational product for the whole brain as well as in parietal and temporal lobes at 3 months, and additionally in the cerebellum and occipital lobe at 6 months of age. These regions are known to be functionally involved in sensory, motor, cognitive, and language functions (2426), such as inhibitory control over reflexive behaviors, target-directed head–eye coordination, reaching to grasp, and hand-to-hand transfer around 6 months of age (27).

The mean myelin volumes in our study for 3 (mean = 0.0148, SD = 0.0064) and 6 months (mean = 0.0233, SD = 0.0089) are in line with previously reported measures in larger observational cohort studies (28). The increased longitudinal MWF slopes in the whole brain, CC, parietal, and occipital regions possibly indicate age-appropriate and accelerated neurotypical development in the investigational myelin nutrient blend group. This is in line with neurotypical patterns of myelination, where primary sensory and motor areas myelinate before association areas [for review (29)]. Occipital and parietal lobe myelination has been placed by histological (30, 31) and neuroimaging studies (32) at 4 to 6 months of age. The post-hoc breast-feeding comparisons are for safety purposes and cannot be interpreted as efficacy data due to the limitations of comparing non-randomized arms. No statistically significant differences were identified for myelin volume (MWF) and myelin structure (T2) at 6 months. Some statistically significant differences were found for T1 at 3 months that disappear at 6 months, suggesting initial accelerated growth in the investigational group and a catch-up of the breast-fed group. Such potential early differences at 3 months could be related to maternal dietary intake and/or breast milk level differences for DHA, iron, folic acid, B12, and phospholipids, which were indeed lower in breast milk compared with the investigational product. Two of these, namely iron and folic acid, were in fact lower in breast milk than in the control product, which is in compliance with the United States guidelines for this type of product and target population. Without further data, biological relevance can, however, not be interpreted.

The absence of any measurable group differences in cognitive and behavioral outcomes this early in development appears in line with previous reports. The delayed cord clamping at birth was demonstrated to result in greater myelin content in some brain regions and greater ferritin levels at 4 (33) and 12 months (34) but no significant differences in the cognitive, motor, or language scores. Recent studies comparing enrichment vs. non-enrichment of certain lipid and protein compounds in infant nutrition (35), and comparing different levels of SM in infant formula (14) showed effects on the cognitive development at 1 and 1.5 years of age, respectively. These results suggest a potential temporal gap between intervention and functional changes. Longitudinal observational studies have consistently highlighted a latency between brain structural and behavioral benefits (3, 4, 26), leading to suggest later assessment time points to provide further insight on intervention effects.

The interim data indicate largely comparable findings across the three groups and a trend in slightly higher number of parent-reported constipation in the investigational group (18.8% compared with 5.9% in the control group and 2.8% in the breastfeeding group). A study in healthy term infants receiving standard control formula (N = 57) or formula enriched with a protein-rich milk fat globule membrane (MFGM) fraction (N = 72) or a lipid-predominant MFGM fraction (N = 70) up to 4 months of age reported constipation in 11.4% of the infants in the lipid-rich MFGM (compared with 9.7% in protein-rich MFGM group and 3.5% in standard control formula group) (36). To note, the adverse reports in the present study, should be interpreted with caution, and will be further monitored in the study.

Strengths of the study include the longitudinal RCT design, the breast milk reference group as well as the use of neuroimaging to investigate the impact of a nutritional blend on brain structural development and behavior.

Limitations include the impact of the COVID-19 pandemic on recruitment and retention, resulting in a smaller sample size than expected, which may have impacted possible treatment effects on the cognitive and behavioral variables. Environmental factors that may impact the brain and cognitive development, such as cognitive stimulation and parenting behavior, have not been investigated in the staged statistical analyses. For the full dataset at the study end, additional measures, such as day care attendance, parenting stress, and child activity levels will be available.

The investigational exploratory nature of the study requires cautious interpretation of the inferential statistics as type-I and type-II errors are uncontrolled. To mitigate this, the number of computed p was kept to a minimum. Lastly, the myelin imaging data were only analyzable from one of the two study sites due to acquisition issues with the myelin sequence. T1 and behavioral data were, however, unaffected and usable from both clinical sites.

Our findings add important insights into early brain architecture development. They highlight the opportunity to improve the developmental (i.e., de novo) myelination, a critical process in learning and development, via nutritional intervention in healthy infants.
