Fucoidan is a bio-active component of Undaria Pinnatifida (Wakame) and other brown sea vegetables. It is one of the most heavily studied of natural bio-active substances in the world. There are over 100 peer reviewed and published scientific studies that use Fucoidan as a subject. Many are looking at it as a promising anti cancer drug while others are focused on its effects on skin, intestinal tract and as an absorber of heavy metals and radiation. There are compelling studies that look at its ability to act as a effective antiviral and antibacterial agent. Others look at its role as a powerful antioxidant. Here are a small sample of these studies. More information about these and other studies can be found at PubMed, a database of scientific studies maintained by the US National Library of Medicine and the National Institutes of Health.
