Matrix MOS is a unique form of 1-3 & 1-6 beta glucans that help stimulate the immune system of animals and humans. MOS is an insoluble Mannan Oligosaccharide and Beta-glucan complex that has been extracted from the cell wall of yeast.

Beta-Glucan

Promote the reproduction of beneficial bacterial. Adjust microflora balance in intestine and stomach. Absorb pathogens and control diseases. Beta-glucan serves an important role as the most potent known stimulator of the immune system for animals. Beta-glucan creates a gel like substance that slows the transit of digesta throughout the gut and allowing starches to begin digesting earlier in the system, in doing so reducing the negative effects of starch in the hind gut, predominantly due to the spawning of pathogens.

MOS

Yeast extracts have been found to bind pathogens. Reasons are because their mannan oligosaccharide (MOS) content mimics the carbohydrates in the enterocyte membranes. Pathogens are fooled into binding with MOS instead of the enterocytes, and are subsequently flushed out of the digestive system. Along with the pathogens go the toxins they would have produced.
MOS can be digested by the enzymes of certain beneficial bacteria. So, in addition to discouraging pathogenic bacteria, MOS also promotes the growth of beneficial microbes such as lactobacillus.
MOS also stimulates the immune system and encourages the growth of intestinal villi, showing improved digestion and absorption of nutrients in various animal studies.
