Fucoidan is a complex sulfated polysaccharide found in the cell walls of brown seaweed. This marine flora, which includes species like kombu, wakame, and bladderwrack, is the primary raw material for extracting fucoidan. Its growing prominence in the health and wellness industry has driven interest in understanding its natural source.

Fucoidan was first isolated in 1913 from a species of brown algae. Fucoidan is primarily found in the cell walls of brown seaweeds and certain marine invertebrates, and its properties vary widely depending on the source. Commercially extracted from species such as *Fucus vesiculosus* and *Undaria pinnatifida*, this sulfated polysaccharide is prized for its diverse biological activities.
