Alginate Oligosaccharide Prebiotic & Bioactive Polysaccharide

AOS Powder Immunity, Skin & Health Support

Alginate Oligosaccharide (AOS) – High-Purity Bioactive Oligosaccharide for Immune, Skin, and Health Applications

Alginate Oligosaccharide (AOS) is a low-molecular-weight oligomer derived from brown alginate, a polysaccharide widely found in various brown algae such as kelp, wakame, and giant kelp. Produced via enzymatic degradation of brown alginate using β-eliminase alginate lyases, AOS retains the physicochemical properties of alginate while exhibiting enhanced solubility, absorption, and bioactivity. Its degree of polymerization (DP) is controllable (2–7), with molecular weight <1000 Da, making it ideal for functional foods, nutraceuticals, pharmaceuticals, and cosmetics.

AOS has been shown to possess prebiotic, metabolic, immune-modulating, antibacterial, antioxidant, antitumor, and plant-growth-promoting properties, making it a highly versatile ingredient for global B2B manufacturers, wholesalers, and brand owners.
