Product Detailed Description
Fucoidan (CAS No.: 9072-19-9) is a natural sulfated polysaccharide extracted from brown algae (Latin name Phaeophyceae, such as kelp and giant kelp). Fucoidan 50% is light yellow powder. Our Fucoidan 50% features a minimum total sugar content of 50.0%, with fucose ≥15.0% and sulfuric acid base ≥20.0%-far exceeding industry basic standards.
Produced via advanced water-based physical extraction technology, it retains maximum active ingredients without organic solvent residues, ensuring product safety and purity. The product presents as near white or light yellow to brown powder, with a molecular weight range of 30,000-200,000 Daltons-small enough for enhanced bioavailability while maintaining structural stability.
It is fully water-soluble, has a pleasant taste, and meets strict quality requirements with ultra-low heavy metal and microbial levels. It caters to B2B needs across functional foods, beverages, nutraceuticals, and cosmetics sectors, complying with global regulatory standards for Europe, North America, and Asia.
