简要总结
The goal of this study is to assess the impact of Layer Origin's SuperHMO prebiotic formulation on the healthy adult gut microbiome. Over the course of 30 days, intervention participants will take SuperHMO prebiotic formulation daily. Control participants will take a placebo daily. We will measure all participants' gut microbiome using a gut health test before taking SuperHMO prebiotic or placebo and after 30 days of taking the supplement. We hypothesize that taking the SuperHMO prebiotic will improve gut health measurements such as the potential to produce short-chain fatty acids.
详细描述
The investigators will enroll 24 healthy, adult volunteers into this double-blinded, randomized, placebo-controlled trial. Upon confirmation of eligibility and documentation of informed consent, the participants will be randomized to either SuperHMO (Layer Origin, 53% 2'FL, 15% LNT, 14%LNnT, 12% 6'SL, 6% 3'SL) prebiotic formulation at a dosage of (4.2 g/day) or placebo (maltodextrin, 4.2 g/day), self-administered at home and taken as a liquid solution in a beverage of choice by mouth once daily for 30 days. Participants will take a baseline survey at the beginning of the study and an exit survey at the end of the study assessing their current health, health history, diet, current and past supplement and medication use, and any GI symptoms or bowel irregularities. Participants will additionally take a baseline microbiome sample before beginning the daily regimen of taking the supplement or placebo for 30 days. At the end of the study, participants will take another microbiome sample and an exit survey to report changes to gut health, overall health, diet, and any adverse reactions. Gut microbiome outcomes will be analyzed both intra-individually, as a before and after comparison, and inter-individually to compare intervention and control groups.

研究组 & 干预措施
Intervention - SuperHMO
The investigation product is commercially available and is marketed as SuperHMO Prebiotic Mix with 5 HMOs. This product is a dietary supplement which contains five major types of human milk oligosaccharides includes 2'-Fucosyllactose (2'-FL), Lacto-N-tetraose (LNT), Lacto-N-neotetraose (LNnT), 6'-Sialyllactose (6'SL), and 3'-Sialyllactose (3'SL). SuperHMO is designed to boost the number and variety of beneficial bacteria in the gut by feeding them with five different kinds of human milk oligosaccharide prebiotics. This product does not contain any flavoring, colorants, preservatives or fillers. Each bottle contains 118 grams of the mix, 28 servings, with 4.2 grams per serving (2 scoops).
Study participants will be instructed to take 1 scoop (2.1 g) per day for the first five days and increase to 2 scoops (4.2g) per day for days 6-30, the formulation can be dissolved in their beverage of choice and taken at any time of the day, with or without food.
干预措施: SuperHMO (Dietary Supplement)
Control
Control participants will receive a commercially available maltodextrin, NOW Sports Nutrition, Non-GMO corn Maltodextrin, Rapid Absorption. The composition and absorption properties are similar to the investigational product and will be given in the same dosage (2.1g/day for days 1-5 and increasing to 4.2 g/day for days 6-30) and route of administration as the investigational product. The use of maltodextrin as a comparator in prebiotic supplementation in human trials is well-documented.

结局指标
主要结局
Detection of presence of specific HMO digestion genes
时间窗: 30 days
Comparing baseline and again after 30 days of taking the study product to assess potential changes in HMO metabolism by the gut microbiota.
Quantitative changes in the relative abundance of key bacterial taxa
时间窗: 30 days
The investigators will specifically measure the difference in Bifidobacterium spp., Akkermansia spp., Eubacterium rectale-Clostridium Coccoides group, and Faecalibacterium prausnitzii, at baseline and at 30 days.
Evaluate Changes in Metabolic Markers
时间窗: 30 days
Assess the change in SCFA (namely acetate, propionate, and butyrate) production potential from baseline to 30 days.
Evaluate Changes in Inflammation Markers
时间窗: 30 days
Evaluation of the change in gut inflammatory markers (e.g., hexa-LPS Index, mucus degradation species, hydrogen sulfide levels) between at baseline and at 30 days to investigate potential anti-inflammatory effects of HMO supplementation.
Assess Changes in the diversity metrics of the Gut Microbiome
时间窗: 30 days
Measuring the change in alpha diversity (e.g., Shannon index) and beta diversity metrics (e.g., Bray-Curtis dissimilarity) to evaluate overall microbial diversity and community structure shifts between baseline and at 30 days.
