Okinawa Fucoidan


Fucoidan is a slippery substance contained in seaweeds such as mozuku, kelp, and brown seaweed. In recent years it has been established that fucoidan is good for our bodies, and fucoidan has gained popularity as a functional product ingredient. Compared to other varieties of seaweed, the Okinawa mozuku has an especially high content of fucoidan. Okinawa mozuku grows in the coastal seas surrounded by coral reefs.
Mozuku cultivation is not easy. Every October divers have to go to the bottom of the sea to drive metal rods into the seabed in order to then attach nets with mozuku spores to the rods in January. Benefitting from an abundance of sun and blessed with the Kuroshio sea current, the spores grow into mozuku seaweed about 30 cm long by March or April. Harvesting begins in March and ends in middle of June. Crop failures sometimes occur depending on weather conditions in early spring. The medically proven effects of fucoidan include anti-tumor, anti-ulcer, intestinal regulation, laxative, anti-cholesterol, blood clotting prevention, hair restoration, anti-allergic, anti-virus, and arterial sclerosis prevention effects. It has also been shown to have positive effects on atopic dermatitis, high blood pressure, diabetes, impaired hepatic function, and chronic hepatitis C. Fucoidan has no side-effects.

The largest Japanese fucoidan manufacturers are: Kanehide Bio (Okinawa), Orihiro, Umi No Shizuku, Yoho Mekabu, Fine
