Alginate oligosaccharide

"DK-AOS is composed of D-mannuronic acid and L-glucuronic acid with weight-average molecular weight not exceeding 5000 Da. 1) Prebiotic effects DK-AOS is a new marine prebiotic that can significantly promote the abundance of the new-generation probiotics such as Bacteroides xylanisolvens and Faecalibacterium prausnitzii,promote the synthesis of short-chain fatty acid, and improve intestinal immunity. 2) Improving memory DK-AOS has significant memory improvement effects. Based on the brain-gut axis theory, DK-AOScan reshape the balance of gut microbiota, inhibit the abnormal increase of specific metabolites in gut microbiota, reduce peripheral and central inflammation, thereby improving cognitive impairment. 3) Enhancing immunity DK-AOScan significantly improve immunity, regulate various types of cytokines and complement, and has good activation and induction effects on non-specific immunity and specific immune system. 4) Antioxidant DK-AOS has significant antioxidant effect and can alleviate alcohol-induced liver damage, Parkinson's and other diseases caused by oxidative stress. 5) Otheractivities  Moisturizing Effects: DK-AOS can lock skin moisture, keep skin fresh and smooth, and make skin more elastic.  Delay Cell Aging: DK-AOScan effectively eliminate free radicals such as superoxide anion (O2-), hydroxyl radical (OH-), hydrogen peroxide (H2O2) that cause skin aging and spots, and delay cell aging.  Skin Repair: DS-AOS can promote the migrationof L929 cells and can be used for repairing damaged skin."
