Unique formula of Umi No Shizuku Fucoidan

Most commercially available fucoidan products have different concentrations and ingredients, which determine their price and functional variation. Each capsule of the Umi No Shizuku Fucoidan contains 250mg of active ingredients, with 212.50mg of fucoidan taking up 85% of the total capsule. The rest are refined powder from the mycellium of Agaricus mushroom, its studies have shown that by mixing with Umi No Shizuku Fucoidan can effectively improve immunity.

Okinawa Mozuku Fucoidan

The Mozuku from Okinawa is a type of brown seaweed. Analysis has shown that Mozuku contains the highest level of fucoidan than any other types of seaweeds in the world. The purified ingredients (sulfate group) in the Umi No Shizuku Fucoidan are higher than other products, and true to its name.

Mekabu fucoidan

The Mekabu fucoidan is extracted from the root portion of the Mekabu (Undaria pinnatifida), which contains high purity of fucoidan and rich in proteins, vitamins and minerals.


Umi No Shizuku has also added powders from the mycellium of Agaricus mushroom, which has been shown by scientific research to naturally enhances immunity. The polysaccharide of the Agaricus contains high level of Beta glucan. When combined with the fucoidan, the immunity can be effectively enhanced further. An independent study showed that the combination of fucoidan and Agaricus is more effective than individual usage, and can better exert their potential synergistic effects.

The production of Umi No Shizuku Fucoidan

Umi No Shizuku Fucoidan is produced under strict quality control. We only use fresh Mozuku seaweed from the water of Okinawa for our production. The main reason being that the sulfates in fucoidan will expire in dried Mozuku, and sulfate is an important ingredient of fucoidan. We produce only the finest quality of fucoidan under our stringent quality control.

The Fucoidan is 100% produced by cGMP manufacturers in Japan under strict quality control, and has been marketed for more than a decade in Japan and the United States. The U.S. FDA has tested the ingredients to be safe for consumption, and has been tested by the Hong Kong SGS to be free of radioactive material. The NPO Research Institute of fucoidan in Japan also uses the Umi No Shizuku Fucoidan in scientific research on the effects of fucoidan on human immunity, citing the excellent product quality and authentic product composition as the main reasons. The results of their research were published on PubMed (a database of biomedical scientific journals and articles maintained by the United States National Center for Biotechnology Information) as reference articles. PubMed has collected scientific literatures dating back to 1953 from more than 70 countries and in more than 40 different languages, containing articles from over 4,600 biomedical scientific journals. More than 1,000 articles on fucoidan can be found in the database.
