We're launching a study to observe the impact of a prebiotics on the infant gut and constipation
Your participation could help us explore how human milk oligosaccharides (HMOs) in the supplement affect gut health. In partnership with Begin Health, we intend to publish our findings when the study concludes.
Constipation in children is very common, with a reported frequency of up to 30%
Most children with chronic constipation are caught in a vicious cycle The cycle can start at any point and deepen its roots with each revolution.
Human Milk Oligosaccharides (HMOs) are known to selectively promote the growth of beneficial bacteria like Bifidobacterium in infants, establishing an optimal gut microbiome composition. This can contribute to the development of a robust immune system and improve symptoms of constipation. The goal of this study is to assess the efficacy of HMOs and prebiotic supplements on modulating the infant gut microbiome. All participants will take either an HMO supplement or a placebo once daily for 30 days. Each participant will also take a gut microbiome test at the beginning and end of the study.

Interested individuals will submit their details including age, probiotic usage, and review the checklist against any health conditions via email. If you qualify for the study, a clinical coordinator will meet with you virtually to enroll you in the study and sign consent forms.
Both gut samples can be taken at home by using our swab method. Samples will be mailed in using a prepaid envelope provided with the kit.
You will fill out health history and exit surveys upon sampling.
Processed in a CLIA-certified lab and using proprietary technology, Tiny Health’s gut health test provides strain-level precision and a complete list of all microbes in the vaginal and gut microbiome including bacteria, fungi, virus, parasites, and archaea. Results will take 4-5 weeks to arrive.
Consent to the study
The study is suitable for US residents who are 1-3 years old.
Receive gut test results at the completion of the study
Every report includes a personalized expert note that is reviewed by a team of microbiome experts.
Tiny Health also provides actionable, and evidence-based recommendations to parents to help them learn about their child's gut health and course-correct and gut imbalances.
The microbiome result report and action plan are a part of the regular Tiny Health Gut Test product and not associated with the research study.
You will be eligible to receive $100 in compensation at the completion of the study and all required surveys.

Frequently Asked Questions
There is no cost to participation. You must be capable of taking two microbiome stool samples and filling out two surveys online. Collecting a microbiome sample can be done on your own time, at home, and should take a few minutes. Each of the surveys can take anywhere between 5-15 minutes to complete, depending on the complexity of your answers. The total duration of the study is meant to conclude after taking the supplement for 30 days and completing your second sample and exit survey.
You will receive $100 in compensation at the end of the study when you have fulfilled all study responsibilities to include mailing two microbiome samples back to our lab and completing both surveys. All study participants will receive their full adult gut microbiome reports, including all evaluations and recommended action plan, approximately 4-6 weeks after the study is complete.

The risk of personal information or microbiome data being exposed is a possibility. To prevent this risk, all personal information is stored in encrypted databases with access limited to dual authentication select employees. Stool samples are de-identified using a kit id before being sent to partners for DNA extraction and sequencing.
