Trial Summary

Will I have to stop taking my current medications?

The trial requires that you stop using antibiotics, laxatives, and antidiarrheal medications before participating. If you are using any of these, you will need to stop them to be eligible for the study.

What data supports the effectiveness of the treatment Mannooligosaccharides for gut health in healthy older adults?

Research on similar prebiotics like galacto-oligosaccharides (GOS) shows they can increase beneficial gut bacteria, such as bifidobacteria, in older adults, which may help improve gut health.12345

Is Mannooligosaccharides (MOS) safe for human consumption?

While specific safety data for Mannooligosaccharides (MOS) is not provided, similar prebiotics like xylooligosaccharide (XOS) have been shown to be well-tolerated without significant gastrointestinal side effects in healthy adults.46789

How does the MOS prebiotic treatment for gut health in healthy older adults differ from other treatments?

The MOS prebiotic treatment is unique because it specifically targets gut health by enhancing the diversity of beneficial gut bacteria, which is particularly important for older adults. Unlike other treatments, MOS focuses on modulating the gut microbiota composition, potentially improving overall gut health and resilience in this age group.110111213

What is the purpose of this trial?

Mannooligosaccharides (MOS) derived from baker's yeast may have prebiotic properties such as improving gastrointestinal function. The aims of this study are to determine the effect of MOS on gastrointestinal function and symptoms and fecal microbiota in older adults.

Findings from Research

In a study involving 30 obese women over 3 months, treatment with inulin-type fructans (ITF prebiotics) significantly altered gut microbiota composition, increasing beneficial bacteria like Bifidobacterium and Faecalibacterium prausnitzii, which are linked to lower serum lipopolysaccharide levels.
The ITF prebiotics also resulted in a slight decrease in fat mass and changes in plasma metabolites, suggesting that these prebiotics can modestly influence host metabolism and may have implications for obesity and diabetes management.

In a study using fecal cultures from healthy and morbidly obese adults, different prebiotics were tested, revealing that 1-kestose had the most significant impact on gut microbiota composition and metabolic activity.
Prebiotic modulation led to increased Bacteroides and Faecalibacterium in obese individuals, while normal-weight individuals showed higher levels of Bifidobacterium and Faecalibacterium, highlighting the need for tailored prebiotic treatments based on individual microbiota profiles.
