MOS (Mannan Oligosaccharides)
A prebiotic that supports gut health by binding to pathogens.
Also known as: Mannan Oligosaccharides
Overview
Mannan oligosaccharides (MOS) are a type of carbohydrate derived from the cell wall of the yeast Saccharomyces cerevisiae. They are considered prebiotics that work in a different way than fibers like inulin. Instead of feeding beneficial bacteria, MOS functions by binding to and removing pathogenic bacteria from the gut.
Key Benefits
Supports a Healthy Gut Microbiome
MOS helps to maintain a favorable balance of gut bacteria by preventing harmful bacteria from adhering to the intestinal wall.
Enhances Immune Function
By reducing the pathogen load in the gut, MOS can help to support the immune system.
Improves Digestive Health
Can help to reduce the incidence of digestive upset caused by pathogenic bacteria.
Dosage & How to Take
Doses of 1-4 grams per day are typically used for supporting gut health. It is often found in combination with other digestive health supplements.
