MOS 

Mannanoligosaccharides (Bio-MOS) is a prebiotic-type product that is derived from yeast cell walls (usually from a specific strain of Saccharomyces cerevisae). MOS is considered to be a prebiotic because it is not broken down by the host animal's digestive enzymes but can be used as a 'food' source for beneficial bacteria that inhabit the natural flora of the digestive tract.
