Fucoidan 85-98% supplier specification
Nutrition BioTech is a bulk fucoidan ingredient supplier and manufacturer, supplying brown-seaweed fucoidan (CAS 9072-19-9) at 85% to 98% fucoidan content depending on grade, produced by aqueous extraction and purification of brown algae, for B2B nutraceutical and cosmetic formulation.
Fucoidan is a sulfated polysaccharide rather than a single small molecule, so it has no fixed molecular weight; material is defined by seaweed species, fucoidan content, sulfate content and molecular-weight distribution. Iodine and heavy-metal control are the standing questions for any marine polysaccharide, and both are addressed per lot on the Certificate of Analysis.
| Ingredient name | Fucoidan 85-98% |
|---|---|
| Synonyms | Fucoidin; sulfated alpha-L-fucan; sulfated fucose polysaccharide; brown seaweed polysaccharide |
| CAS number | 9072-19-9 |
| Molecular formula | Not applicable — polydisperse sulfated polysaccharide built on an L-fucose backbone with sulfate ester groups, plus minor galactose, mannose, xylose and uronic acid units depending on species. |
| Molecular weight | No single defined value; molecular-weight distribution varies with species and process and is reported per grade where a buyer specifies it. |
| Assay / purity | Fucoidan content 85% to 98% depending on grade; the exact grade, assay method and assay basis are specified per order and stated on the Certificate of Analysis. Sulfate content and fucose content are reported alongside assay. |
| Source / production route | Aqueous extraction and purification from brown seaweed (Fucus vesiculosus, Undaria pinnatifida or Laminaria japonica depending on grade). Species, harvest region and process are stated on the specification sheet, since species determines the sulfation pattern. |
| Appearance | Off-white to light brown or beige powder |
| Solubility | Soluble in water, forming viscous solutions at higher concentrations; insoluble in ethanol and most organic solvents. Viscosity behaviour should be confirmed for beverage and topical bases. |
| Typical applications | Capsules, tablets, sachets, powder blends and topical cosmetic bases for B2B manufacturing; commonly formulated alongside marine collagen, prebiotic fibre and immune-positioned ingredients |
| Documentation | Certificate of Analysis, specification sheet, species and origin declaration, fucoidan and sulfate content, iodine content, heavy metals including arsenic speciation on request, microbiological testing, residual solvents, allergen statement, GMO statement and stability data |
| Quality system | ISO 22000:2018, FSSC 22000, HACCP and GMP (certificates provided on request) |
| Supplier | Nutrition BioTech, 1601 W. Mission Blvd, Suite 103 (DL#29), Pomona, CA 91766, United States |
Fucoidan 85-98%
High-purity fucoidan for marine wellness, immune and skin-longevity formulas.
Why brands ask for it
Fucoidan 85-98% gives brands a premium marine polysaccharide story for immune, gut and skin-longevity positioning. Buyer confidence depends on source control, purity, heavy metals, iodine discussion and consistent documentation.
Finished-product fit
Marine wellness, immune support, gut support, skin hydration/beauty-from-within. The strongest conversations start with format, serving size, documentation, and how the material behaves in the intended formula.
What makes the sample useful
- High-purity fucoidan
