Evaluating the Effects of an Oral Protein Supplement on Children's Growth Patterns

Overview

This single-center, randomized controlled pilot study aims to evaluate the efficacy of TruHeight Growth Protein Shake on improving growth patterns in children aged 4-17 years. Over six months, participants will consume the protein shake daily, five times a week, with outcomes measured in terms of type X collagen concentration in urine, height via a stadiometer, and body composition using an INBODY device.

This single-center pilot clinical trial was conducted for TruHeight to determine the effect of oral protein supplement (Growth Protein Shake-GPS) versus control on growth patterns in children. The hypothesis posits that GPS protein supplementation will improve growth patterns as assessed by the concentration of collagen X in the urine, height as measured by a stadiometer, as well as weight and body composition as measured by an INBODY device in six months. The oral supplement was provided in powder form, which could be mixed with water before consumption. Participants were recruited from the SF RESEARCH INSTITUTE database and through advertisements on social media and public places. Initial attendance at SF RESEARCH INSTITUTE marked the baseline study visit, where subjects underwent screening for eligibility based on the Inclusion and Exclusion Criteria. Upon meeting qualification criteria, enrollees were assigned a subject number sequentially as they joined the study. A total of 32 subjects, aged 4-17 years, embarked on the study, targeting a completion cohort of 20. Randomization into either the treatment/supplement group or control group occurred via a computer-generated code. The trial comprised three study visits (SV) over a 6-month period. Measurements of height, weight, fat mass, and lean body mass took place at baseline (SV1), 3 months ± 5 days (SV2), and 6 months ± 5 days (SV3). Urine samples collected at SV1 and SV3 underwent laboratory analysis for type X collagen content. Depending on the group assignment, a dietary or consumer perception questionnaire was provided to be completed by the participant or the participant's guardian at baseline, SV2, and SV3. Treatment group participants or their guardians received a log form to document supplement intake at home. Maintenance of regular diet throughout the study was mandatory for all participants. Instructions for subjects in the treatment/supplement group were as follows: Mix and consume two (2) scoops of the dietary supplement with 12-16 fluid oz of water daily, five times per week, for 6 months. The investigator initiated follow-up calls to subjects or their guardians on day 45 (between SV1 and SV2) and day 120 (between SV2 and SV3) to assess compliance with the study protocol.
