We aimed for a new form of fucoidan Sea Fucoidan's own ultra-low molecular​ ​ Sea Fucoidan DX can absorb fucoidan smoothly in the body by making the whole molecule components as low as possible by using unique technology cultivated over many years. The molecular weight of fucoidan originally exceeds 200,000. It is said that it is approximately (molecular weight 3000) for human beings to absorb into the body, so it is almost directly discharged outside the body as it is. Sea Fucoidan DX achieves efficient absorption of fucoidan into the body by setting the average molecular weight to 500 or less.
