What is Fucoidan?
Fucoidan,
present in brown algae just like hondawara, was discovered in 1913 by Professor
Kylin of Uppsala University
in Sweden
as a source of sliminess of kombu. Initially named “fucoijin,” the substance
subsequently became known as “fucoidan” based on the international naming
convention on sugars.
Types of Fucoidan:
Fucoidan
is a specific source of sliminess only found in brown algae such as kombu,
wakame (mekabu) and mozuku, and a type of water-soluble dietary fiber. Chemically,
fucoidan is a high-molecular polysaccharide whose main constituent is sulfated
fucose. In addition to fucose, the saccharide chain that constitutes fucoidan
also includes galactose, mannose, xylose and uronic acid. The name “fucoidan”
does not represent substances of a given structure, but it is a general term
that refers to high-molecular polysaccharides whose main constituent is fucose.
Use Purposes:
·
To boost the
immune system: In vitro data suggest a role for fucoidan in boosting host
defense mechanisms. Several human studies also suggest it may help stimulate
immune functioning and boost antibody production after vaccination.
·
To reduce
inflammation: Several in vitro and animal studies suggest that fucoidan
has anti-inflammatory properties. Human studies are needed.
·
To prevent
cancer: Several in vitro and animal studies show that fucoidan has
antitumor properties. Clinical trials have not been conducted.
·
To lower blood
pressure: A study in overweight and obese adults suggests that fucoidan
use over a sustained period may decrease diastolic blood pressure and as well
as “bad” cholesterol levels. Studies to confirm these results are needed.
·
To prevent
blood clots: Laboratory studies suggest that fucoidan has anticoagulant
and antithrombotic effects. A study in humans also suggests it slows the
production of blood clots. As such, fucoidan may interfere with blood-thinning
medication.
·
To prevent
infections: Laboratory and animal studies indicate that fucoidan has
antiviral properties.
