What is Fucoidan?



Fucoidan, the key ingredient present in marine brown seaweeds such as  KombuWakame (Mekabu), and Mozuku, was first isolated in 1913 by Professor Kylin of Uppsala University in Sweden. He was the first person paving the way to this fascinating and 100% natural ingredient. Since then, Fucoidan has been extensively studied due to its great benefits.  

Fucoidan is a specific source of sliminess found only in brown seaweeds and a type of soluble dietary fiber. Chemically, fucoidan is a group of high-molecular polysaccharide whose main constituent is sulfated fucose. Fucoidan is a polysaccharide containing substantial percentages of L-fucose and sulfate ester groups, which are constituents of brown seaweeds and other marine invertebrates. In addition to L-fucose, the saccharide chain also includes galactose, mannose, xylose and uronic acid. This means that fucoidan has a unique molecular structure, which makes it a unique natural health ingredient. 

The polysaccharide was initially named “fucoidin” when it was first isolated. Now it is named “Fucoidan” according to IUPAC rules. The name "Fucoidan" is a general terms that refers to high-molecular polysaccharides whose main constutient is fucose.
