01. Fucus Vesiculosus Extract – Bulk Supplier, Specifications & OEM Manufacturing Guide
Fucus Vesiculosus Extract is a marine-derived botanical ingredient widely used in dietary supplements, functional foods, and cosmetic formulations. As global demand grows for traceable seaweed extracts with standardized quality and regulatory compliance, professional buyers increasingly prioritize consistent specifications, verified COA data, and GMP-certified manufacturing.
AIHerba® supplies high-quality Fucus vesiculosus extract powder produced under strict quality control, with clearly defined fucoidan content, iodine specification, and full contaminant testing. Our extract is designed for bulk procurement, private label manufacturing, and OEM/ODM formulation, supporting nutraceutical brands, cosmetic laboratories, and ingredient distributors worldwide.
This page provides a technical, application-focused, and procurement-oriented overview—covering raw material sourcing, extraction technology, quality parameters, regulatory considerations, and real-world industry use cases—helping B2B buyers make informed sourcing decisions with confidence.
02. What Is Fucus Vesiculosus Extract?
Fucus vesiculosus, commonly known as bladderwrack, is a brown seaweed native to cold North Atlantic coastal regions. The extract is obtained from dried algal biomass through controlled aqueous or hydro-ethanolic extraction, concentrating naturally occurring marine polysaccharides and polyphenols.
From an ingredient perspective, Fucus vesiculosus extract is valued not as a drug or therapeutic agent, but as a functional marine botanical used in formulations that emphasize mineral content, polysaccharide structure, and natural origin.
Key characteristics valued by professional buyers include:
-
Marine-derived polysaccharide profile
-
Naturally occurring iodine (controlled & standardized)
-
Compatibility with supplement, food, and cosmetic systems
-
Traceable botanical source and batch consistency
03. Botanical Source & Raw Material Origin
-
Botanical name: Fucus vesiculosus L.
-
Family: Fucaceae
-
Plant type: Brown macroalgae
-
Harvest regions: North Atlantic coastal waters
-
Raw material form: Dried whole algae
All raw materials are sourced from approved harvesting zones, with supplier qualification and traceability documentation maintained throughout the supply chain.
04. Key Functional Components (Ingredient-Level View)
Fucoidan (Sulfated Polysaccharides)
Fucoidan is a complex sulfated polysaccharide commonly studied in brown algae. In formulation science, it is valued for its structural properties, water solubility, and compatibility in multi-ingredient systems.
Polyphenols (Phlorotannins)
Marine polyphenols contribute to oxidative stability and are of interest in cosmetic and functional food applications.
Naturally Occurring Iodine
Iodine content is intrinsic to Fucus vesiculosus and must be quantified and controlled to meet regional regulatory expectations.
AIHerba standardizes extract batches to ensure predictable composition and labeling accuracy, a critical requirement for international brands.
