What is Fucoidan (Undaria pinnatifida extract, Wakame extract)?

Fucoidan powder (Undaria pinnatifida extract, Wakame extract) is a sulfated polysaccharide found mainly in various species of brown algae and brown seaweed such as mozuku, kombu, bladderwrack, wakame, and hijiki. It is used as an ingredient in some dietary supplement products.

Fucoidan designates a group of certain fucose-containing sulfated polysaccharides. It offers several potentially beneficial bioactive functions for humans. The bioactive properties may vary depending on the source of seaweed, the compositional and structural traits, the content, distribution, and bonding of the sulfate substitutions, and the purity of the Fucoidan product. The preservation of the structural integrity of the Fucoidan molecules essentially depends on the extraction methodology which has a crucial, but partly overlooked, significance for obtaining the relevant structural features required for specific biological activities and for elucidating structure-function relations.

What is Undaria pinnatifida?

Undaria pinnatifida is a sea vegetable, or edible seaweed. It has a subtly sweet flavour and is most often served in soups and salads, and it can help burn fatty tissue.

Fucoidan (Undaria pinnatifida extract, Wakame extract) benefits


Fucoidan powder (Undaria pinnatifida extract, Wakame extract) fights cancer by immune cell activation and increased production of anticancer cytokines. It blocked cell growth, caused programmed cell death, and suppressed formation of new blood cells in thyroid cancer cells.


It protect against many different species of viruses, and it may be capable of preventing HIV infection by blocking the enzymes needed by the virus to replicate. More over, it demonstrated potent antiviral activity against herpes of all types.

Protect Brain

It prevented overactivation of microglia that may lead to neurodegeneration. Treatment with fucoidan reduces the encephalitogenic response in encephalomyelitis.

Against Radiation

It provided protection from radiation in cells, it prevented gut inflammation and increased the length of villi in the gut.

Protect Stomach and Liver

It inhibit Helicobacter infections in the stomach by preventing the bacteria from sticking to gut walls, and prevent the ulcers from developing. More over, it reduce alcohol-induced fatty liver disease.
