An Exploratory Study on the Anti-inflammatory Effects of Fucoidan in Relation to Quality of Life in Advanced Cancer Patients.


Conventional anticancer therapies still cause difficulties with selective eradication and accompanying side effects that reduce patients' quality of life (QOL). Fucoidan is extracted from seaweeds and has already exhibited broad bioactivities, including anticancer and anti-inflammatory properties, in basic studies. It is expected to enhance therapeutic efficacy and minimize side effects in cancer patients; however, despite its potential benefits, there are very few clinical trials using fucoidans. Therefore, we performed an exploratory clinical study for advanced cancer patients to examine the efficacy of fucoidans, especially focusing on inflammation in relation to QOL scores.

NPO Research Institute of Fucoidan

Our organization has carried out the following activities based on our "philosophy, beliefs, and missions" aiming to help people live healthy and comfortable lives through diet, by widely disseminating the benefit of "fucoidan" which is a high molecular polysaccharide, extracted from seaweed (brown algae). Fucoidan is said to have a natural healing power (immunity) activation component.

We have conducted a variety of joint research and experiments with Kagoshima University and Kyushu University in our attempt to discover the cancer stopping effects and other efficacy of fucoidan, and have shared the research results and information.

A draft genome of the brown alga, Cladosiphon okamuranus, S-strain: a platform for future studies of ‘mozuku’ biology 

Cladosiphon okamuranus (Chordariales, Phaeophyceae),5 Okinawa mozuku in Japanese, is one of the important edible seaweeds. In Okinawa, C. okamuranushas been cultivated for more than 35 years by several fishermen’s associations, including those in Onna and Chinen Villages. This cultivation history has established several strains of mozuku that have similar morphology and texture. It was reported in the 36th annual report of the Japanese Cabinet Office that approximately 20 kilotons of mozuku (C. okamuranus and Nemacystus decipiens (‘Itomozuku’)) are produced annually, yielding approximately 4 billion Japanese yen in 2006. In addition, C. okamuranus and N. decipiens are sources of fucoidan,6 a sulfated polysaccharide found in the cell-wall matrix of brown algae that has anti-coagulant, anti-thrombin-like, and tumor-suppressant activities.7 Brown algae also produce alginates.8,9

FDA Response to the Fukushima Dai-ichi Nuclear Power Facility Incident
March 2014 Update

To date, FDA has no evidence that radionuclides from the Fukushima incident are present in the U.S. food supply at levels that would pose a public health concern. This is true for both FDA-regulated food products imported from Japan and U.S. domestic food products, including seafood caught off the coast of the United States. Consequently, FDA is not advising consumers to alter their consumption of specific foods imported from Japan or domestically produced foods, including seafood. FDA continues to closely monitor the situation at and around the Fukushima Dai-ichi facility, as it has since the start of the incident and will coordinate with other Federal and state agencies as necessary, standing ready to take action if needed, to ensure the safety of food in the U.S. marketplace.
