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.

Regulatory status of Fucoidan
The entries below summarise publicly available regulatory documents and are provided as context for buyers. They are not claims about Nutrition BioTech material, and no health outcome is claimed or implied for any finished product. Authorisation is specific to the source, form and conditions of use described in each instrument. Buyers are responsible for confirming the status of the ingredient in their own market and for the claims they make on their own labels. Last reviewed: 3 August 2026.
Authorised fucoidan extracts in the EU Union list
Fucoidan extracts from the seaweeds Fucus vesiculosus and Undaria pinnatifida are entered in the Union list of authorised novel foods set out in the Annex to Commission Implementing Regulation (EU) 2017/2470. The recorded food category is foods, including food supplements as defined in Directive 2002/46/EC, for the general population, at a maximum level of 250 mg per day.

Authorisation is tied to the seaweed species and the extract specification
The Union list entries are specific to the named seaweed species and to the specification of the extract described in the entry. The designation to be used on the labelling of foods containing the Undaria pinnatifida material is “Fucoidan extract from seaweed Undaria pinnatifida”. Fucoidan obtained from a different species or by a different process is not automatically covered by those entries.

Framework and what buyers should confirm
Novel food authorisation in the EU operates under Regulation (EU) 2015/2283, and an authorisation applies only to the material, specification and conditions of use described in the relevant instrument. The seaweed species, extraction route and specification of the lot supplied should be checked against the intended Union list entry, and against the corresponding requirements of any other target market, before formulating.

- Absolute molecular weight and chain conformation by triple-detection SECMeasured mass and size characteristics of six fucoidans extracted from different algal species by size-exclusion chromatography with triple detection, reporting considerable structural diversity, heterogeneous composition and large differences in molecular weight profiles, with most fucoidan fractions behaving as expanded flexible chains in solution and conformation data suggesting branched structures with partly long side chains.Neupane S, Bittkau KS, Alban S.

- Purification route shapes fraction compositionCompared Fucus vesiculosus fucoidan fractions purified by dye affinity chromatography under different adsorption conditions and reported that the fractions differed in sulfate content and average molecular weight (one fraction averaging 48 kDa), with fucose, galactose and uronic acid/glucose dimers detected in all fractions while xylose appeared only in some – showing that the purification protocol itself shapes the composition of the finished ingredient.Zayed A, Muffler K, Hahn T, Rupp S, Finkelmeier D, Burger-Kentischer A, Ulber R.
