Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Normal aging can lead to loss of gut microbial biodiversity which is linked to inflammaging and immunosenescence or the loss of immunocompetence. Probiotics, such as VSL#3®, and certain herbal supplements such as Triphala are associated with restoration of gut community architecture, increased gut barrier function and decreased inflammation. The present project will examine the potential benefits of a synbiotic (which denotes a prebiotic plus probiotic, and in this study, is an herbal prebiotic plus probiotic) intervention (8 weeks of supplementation) on gut microbiome profiles assessed via stool, inflammatory blood markers, and questionnaires about gastrointestinal health and mood. In this exploratory study, the investigators will examine psychological and physical functioning at baseline and after 8 weeks of supplementation with synbiotic, Triphala alone, or placebo.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Primary Aim: In healthy, cognitively intact elderly subjects, determine the effects of an 8-week synbiotic supplement intervention on the stool microbiome (pre- and post-intervention) as compared to Triphala alone and placebo.

Secondary Aim: In healthy elderly subjects, examine the effects of an 8-week synbiotic supplementation intervention on inflammatory blood markers compared to herb alone or placebo.

Exploratory Aim 1: In healthy elderly subjects, examine the effects of an 8-week synbiotic intervention on gastrointestinal and psychological health via questionnaires compared to herb alone or placebo.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Interested and eligible participants will be randomly assigned to either an 8-week synbiotic group, herb alone, or placebo control with a goal to obtain 60 patients who complete the study (20 in each group) after an estimated 20% attrition. Placebo control subjects will be given the option of having the 8-weeks of herbal synbiotic for directed personal use upon conclusion of the study.

Primary Study Purpose

PREVENTION

Blinding Strategy

TRIPLE

Participants Investigators Outcome Assessors

This study will employ double-blind masking and only the project manager will be aware if the participant is assigned to take the synbiotic, triphala alone, or placebo. At the end of the 8 weeks, participants will be made aware of their randomly assigned supplement.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Synbiotic

Two grams of organic Triphala powder (Banyan Botanicals, Inc.) with 1 capsule VSL#3® (VSL Pharmaceuticals, Inc.) probiotic taken with a few ounces of room temperature water in the morning and at bedtime for 8 weeks. Subjects will be provided both written and verbal instructions and given a kit containing encapsulated Organic Triphala powder (Banyan Botanicals, Inc.) and VSL#3® (VSL Pharmaceuticals, Inc.) capsules.
