Chitosan oligosaccharide (COS) is an oligosaccharide obtained by degradation of chitosan, an animal-derived prebiotic sourced from shrimp and crab shells.
Refers to oligosaccharides and their salts with DP ≤ 10, constructed from glucosamine and/or N‑acetylglucosamine connected by β‑(1,4) glycosidic bonds.
Features higher water solubility and stronger biological activity compared with chitosan.
It can work synergistically with plant-based prebiotics.
Modulate Intestinal Microbiota
Chitosan oligosaccharide (COS) as a natural marine active prebiotic, chitosan oligosaccharide (COS) features multiple benefits and high purity.
It helps regulate gut microbiota and enrich microbial diversity.
Immune Health Support
COS as a positively charged functional oligosaccharide, COS helps maintain healthy immune function.
Metabolic Balance
COS balances bodily metabolism, regulates blood glucose and lowers uric acid levels in the body.
It exerts anti-type 2 diabetes effects via improving insulin resistance, alleviating lipid metabolic disorders.
Also promotes proliferation and secretion of pancreatic β-cells, as well as protecting pancreatic islet cells.
Dietary Supplements
Multiple functional activities enable the development of health foods with various functions.
Such as immune enhancement, intestinal microbiota regulation, auxiliary blood glucose reduction and uric acid lowering.
Functional Beverages
Combined with other active ingredients, it can be formulated into liquid beverages and solid beverages with multiple functions.
Such as anti-fatigue, protection against chemical liver injury and uric acid reduction.
Functional Snacks
Easy to carry for anytime consumption, supporting gut health, antioxidant effects and fatigue resistance.
