Our unique low molecular technology

The difference between Sea Fucoidan and other fucoidans is the unique low molecular technology. Currently you might often hear of a low molecule. Sea Fucoidan is a long-standing low molecular product as a pioneer among them.

We have adopted a unique low molecular technology to realize a systemic absorption close to 100%.

Advanced ultra low molecular technology

Fucoidan is originally said to be a high molecular polysaccharide. It is difficult to absorb it in the body. However, by using our own ultra low molecular technology, we have realized nearly 100% absorption in the body and maintain the function of Fucoidan even if it is very small molecule.

Stable sulfate group bond

We believe that more than 13% of sulfate group bond is necessary for Fucoidan to exert physiological function.    
We have brought about sulfate group formed stably even if it is a low molecule.

Minimize molecular weight ! Maximize Fucoidan's function!

The key to demonstrate the power of Fucoidan is sulfate group. 

We have challenged and succeeded molecular weight to the utmost limit, 500 or less.

Stable binding content is 13% or more 

In order to drink our products without anxiety...

preservatives and artificial color are not used at all.

Raw material

Mozuku (Cladosiphon) grown in Tonga is used in ultra-low molecular weight Fucoidan.

Kingdom of Tonga, Southern Paradise

Fucoidan raw materials include Okinawa Mozuku (Cladosiphon Okamuranus), Mekabu (Turnips) and Konbu (Kelp). We use Tongan Mozuku which is grown in rich ocean.It contains higher Fucoidan with higher quality and secured safety.
