Trial Summary

Will I have to stop taking my current medications?

Participants must not be taking any medications, with a few exceptions for sporadic medication and those that do not significantly affect the gut microbiome. If you are currently on medication, you may need to stop, unless it falls under these exceptions.

What data supports the effectiveness of the treatment Human Milk Oligosaccharide-Based Synbiotic Supplement for gut health?

Research shows that human milk oligosaccharides (HMOs) can increase beneficial bacteria in the gut, improve gut barrier function, and reduce inflammation, which suggests they may help with gut health. These benefits have been observed in infants and adults, indicating potential effectiveness for gut health in other age groups as well.12345

Is the synbiotic supplement safe for humans?

Research shows that human milk oligosaccharides (HMOs), a key component of the synbiotic supplement, are safe and well tolerated in both infants and adults, and they help increase beneficial gut bacteria.12345

How is the HMO-Based Synbiotic Supplement treatment different from other gut health treatments?

The HMO-Based Synbiotic Supplement is unique because it uses human milk oligosaccharides (HMOs), which are naturally found in breast milk and act as prebiotics to promote beneficial gut bacteria. Unlike other treatments, HMOs also enhance immune function and support brain development, making them a novel option for improving gut health.12367

What is the purpose of this trial?

Background:Human intestines are home to a complex gut flora, also called microbiome; this is a natural occurring community of bacteria, fungi, yeast, and viruses. Changes in the balances of the gut flora can lead to illnesses, such as diabetes, colorectal cancer, and inflammatory bowel diseases. Synbiotics are dietary supplements people take to maintain proper balances of their gut flora aiming to improve health.Objective:To find out if a synbiotic supplement can increase the type and amount of beneficial gut bacteria in healthy people as well as improve cardio-vascular protection markers. The supplement contains a natural sugar from human milk.Eligibility:Healthy people aged 18 years or older who eat a typical western diet. They must take no medications (with a few exceptions).Design:Participants will have 2 clinic visits.The first visit will start with screening. They will have a blood test and wait around 2 hours for the results of the blood test. The test will determine if they are eligible for the study.Eligible participants will have additional blood drawn during the screening visit. They will be given a kit to collect a stool sample at home with instructions. They may complete a 3-day food diary. They will meet with a nutritionist and a physician by phone, telehealth, or in person.The supplement is a powder that is mixed with water or another noncarbonated drink. Participants will drink 2 doses per day. Each dose will be 1 hour before or after a meal.The second visit will be about 8 weeks after the first. Participants may repeat the 3-day food diary and nutrition visit. The physical exam, blood tests, and stool sample will be repeated.

Findings from Research

In a study involving 75 children aged 6 to 12 years, supplementation with human milk oligosaccharides (HMOs) like 2'-fucosyllactose (2'FL) significantly increased beneficial bifidobacteria in the gut after 4 and 8 weeks, indicating a positive modulation of intestinal microbiota.
The trial demonstrated that both 2'FL and a mix of HMOs were safe and well tolerated, with no adverse digestive issues reported, suggesting they can be safely used to improve gut health in children.
Human Milk Oligosaccharides Modulate Fecal Microbiota and Are Safe for Use in Children With Overweight: A Randomized Controlled Trial.Fonvig, CE., Amundsen, ID., Vigsnæs, LK., et al.[2022]
Infants fed formulas supplemented with the human milk oligosaccharide 2'-fucosyllactose (2'-FL) showed significantly lower levels of inflammatory cytokines compared to those fed a control formula, indicating a potential immune-modulating effect of 2'-FL.
The immune profiles of infants receiving 2'-FL were comparable to those of breastfed infants, suggesting that 2'-FL supplementation in formula may help mimic some of the immune benefits of breastfeeding.
Similar to Those Who Are Breastfed, Infants Fed a Formula Containing 2'-Fucosyllactose Have Lower Inflammatory Cytokines in a Randomized Controlled Trial.Goehring, KC., Marriage, BJ., Oliver, JS., et al.[2023]
A new method was developed and validated to analyze six specific human milk oligosaccharides (HMOs) that are beneficial for infant health, meeting the AOAC Standard Method Performance Requirements.
This method is non-toxic, automates the removal of excess reagents, and allows for the simultaneous analysis of multiple HMOs, which is important for ensuring the quality of infant formulas and adult nutritionals.
