High Purity & Quality

»"Organic Citric Acid Extraction" (original patented manufacuturing process)

Hydrochloric acid and acetic acid were formerly used to extract fucoidan from mozuku seaweed, but now we can extract high-quality fucoidan without using these chemicals.
We utilize our technology (patent #3408180) to extract fucoidan from the seaweed and further separate it according to its molecular weight through an ultrafiltration process to produce a high-purity and high-quality fucoidan extract. We adjust its molecular weight since this is essential to improve absorption of fucoidan.
