The purpose of this study was to assess the growth and tolerance of pediatric patients who transitioned from a hypoallergenic formula to a pea protein plant-based formula (PPPBF). This was a retrospective cohort study using an online survey completed between May 12 to May 26, 2022. Clinicians entered deidentified data for pediatric patients ages 1 to 18 years old who transitioned to Kate Farms Pediatric Peptide 1.0 (46.6%), Pediatric Peptide 1.5 (19.2%), or Pediatric Standard 1.2 (34.2%).

Transition from a hypoallergenic formula to a PPPBF resulted in improved or stable GI tolerance, weight gain or stability, and demonstrated adherence and safety in pediatric patients (n=73):

  • 94.5% tolerated better or the same

    • 38.4% (n=28) had improved GI tolerance

    • 56.2% had no change in GI tolerance

  • 94.5% gained or maintained weight

    • 64.4% gained weight

    • 30.1% maintained weight

  • 94.5% adhered to treatment plan

  • 98.6% had no adverse reaction§


* Research funding provided by Kate Farms, Inc.

† Clinicians reported improvement in abdominal pain, reflux, diarrhea, constipation, bloating, nausea, vomiting, and/or early satiety.

‡ Adherence defined as receiving at least 75% of the prescribed amount.

§ No adverse reaction was the measure for safety. One patient was noted to have diarrhea.
