Frequently asked questions

What is Fucoidan?
Fucoidan is a type of water-soluble dietary fiber found in the slimy part of the surface of seaweed, and this slimy component acts to protect the body from the outside world. It is also rich in vitamins and minerals, and is an essential component for daily health. It is an extremely valuable component, with only about 1g being extracted from 100g of mozuku seaweed.

High molecular weight fucoidan
Fucoidan is a polymeric component that is connected like a chain at the molecular level. Fucose and sulfate groups combine to create a slimy, gel-like property while retaining moisture. If it becomes a smaller molecule, its properties change and it cannot fully exert its original power. That is why it is important that it is a polymer.

Made with 100% pure Okinawan mozuku seaweed
Okinawa mozuku, grown in the clear, clean waters of Okinawa, has a higher fucoidan content than other seaweeds and contains fewer impurities such as alginic acid, making it an excellent raw material for extracting high-purity fucoidan. Okinawa mozuku, which has absorbed plenty of minerals from the sea, contains nutrients such as fucoidan, dietary fiber, vitamins, calcium, and magnesium. Ryukyu Fucoidan is made using 100% Okinawa mozuku.
Fucoidan is a source of power for daily health support and maintenance.

In 1996, Dr. Derrick DeSilva of JFK Medical Center published a study stating that "fucoidan, a sticky component of seaweed, induces apoptosis in cancer cells." Currently, research is being conducted on the component in the fields of lifestyle-related diseases, immunity, and cancer prevention, and it is attracting attention. In addition, human intervention trials have shown a tendency to enhance immunity, and many pieces of evidence have been reported at academic conferences.
