4 Fucoidan Health Benefits (Including Cancer)

Fucoidan is a type of polysaccharide found in seaweeds that has been researched for its anticancer effects. Preliminary research suggests it may benefit those with osteoarthritis, viral infections, and cancer patients undergoing chemotherapy treatment. Read on to see the potential benefits and mechanisms of fucoidan.

What Is Fucoidan?

Fucoidan is a complex sulfated polysaccharide derived from rich sources such as bladderwrack, other brown algae, echinoderms, and seagrasses 

Fucoidan exhibits many different biological properties [2, 3, 4, 5, 6, 7]:

  • Anti-inflammatory
  • Anti-coagulant (prevents blood clotting)
  • Anti-thrombotic (reduces the formation of clots)
  • Anti-angiogenic (reduces the growth of new blood vessels)
  • Anti-viral
  • Anti-tumor
  • Anti-oxidant

Research in marine food sources has helped reveal many potential remedies for an array of health issues – most being attributable to the presence of fucoidan. However, none of them has been sufficiently investigated.
