Chitosan Oligosaccharide: is a non-toxic functional amino sugar of low molecular weight. It’s made from snow crab shell derived from deep sea with enzymatic degradation. Now it is wildly applied in nutraceuticals, food, feedstuffs and fertilizers, and cosmetics as a new nature raw material.

Characteristics:
Chitosan Oligosaccharides are yellow brown powder, with good water-soluble, easy absorbing, high bioactivity, wide application, natural, non-toxic and harmless features.

COS Bioactivity:
lAnti-cancer & Anti-bacterial
lAntioxidation
lBinds excess fat and inhibits fat absorption
lDischarge of radioactive material
lImmunoregulatory
lImproves digestion and Prevents constipation
lImproves calcium absorption
lImproves liver function
lLowering Cholesterol and blood lipids
lGrowth promotion
