What does fucoidan do and why are these effects important?

For cancer cells, Fucoidan has three main effects:
1. To cause cancer cells to die on their own: Cells in the body normally go through the process of birth, maturation, aging and death. This process is preprogrammed in the gene and is called programmed death (apotosis). Due to a random mutation during development or due to the influence of an external agent, some cells are "shut down" and lose the death stage and continue to grow uncontrollably. Fucoidan contributes to "turning on" the switch of the cell cycle, thereby limiting the growth of cancer cells.

2. Activate the body's natural immunity, increase the body's ability to recognize cancer cells: Cancer cells themselves form from normal cells, so the immune system does not consider them as "foreign factors", then it usually does not attack and destroy to protect the body. Fucoidan helps the immune system recognize the abnormality of cancer cells and activate the immune system to attack these abnormal cells, through that protects the body.

3. Preventing the formation of new blood vessels: If cancer cells want to grow "permanently", they need a supply of oxygen and nutrients, which are new blood vessels. Fucoidan limits the formation of blood vessels or cut off the supply of oxygen and nutrients to cancer cells, thereby "starving" and causing cancer cells to die, limiting metastasis to other cells.
