Fucoidan (CAS 9072-19-9), also known as fucoidin, is a sulfated polysaccharide extracted primarily from brown seaweed species such as Fucus vesiculosus and Undaria pinnatifida.

Where is Fucoidan used?

• Nutraceutical and functional food: incorporated into capsules, tablets, and fortified beverages
• Dietary supplements: immune and digestive health positioning
• Cosmetics: humectant and skin-conditioning agent in serums, masks, and anti-aging creams
• Pharmaceutical: drug delivery matrices and hydrogel systems
• Biotechnology: research reagent and cell culture supplement for cell signaling and receptor binding studies
• It functions as a bioactive ingredient and rheology modifier in pharmaceutical, nutraceutical, and cosmetic formulations.

Good to know: Buyers should confirm source species, extraction solvent, and polysaccharide purity when evaluating lots. Purity levels generally range from 40% to over 85% content, often meeting FCC or USP standards depending on the specific grade.
