Originally derived from the cell walls of yeast for use in animal feed, MOS in a supplement is gaining attention for its potential benefits in human gut health. This natural prebiotic is now being incorporated into dietary supplements to support a balanced intestinal environment and a robust immune system.

According to recent studies, the use of antibiotic growth promoters in animal feed is being phased out in many regions, driving the demand for natural alternatives like prebiotics. One such alternative gaining prominence is MOS, or mannan-oligosaccharides, a complex carbohydrate derived from yeast cell walls that plays a vital role in supporting digestive health and immune function.

Derived from the cell walls of the yeast *Saccharomyces cerevisiae*, mannan-oligosaccharides (MOS) are non-digestible carbohydrates that act as powerful prebiotics, and have been used as a dietary supplement in animal feed since the 1990s. Understanding what is MOS in nutrition requires exploring its dual function in promoting beneficial gut bacteria and binding to harmful pathogens.
