Due to the lack of corresponding decomposing enzymes in the human body, the human body cannot directly absorb kelp polysaccharide by eating kelp. The concentration of laminarin in kelp is too low, so the purification of laminarin is a very expensive and complicated technology. These reasons lead to people's lack of comprehensive and correct understanding of laminarin.

Japan is the first country to develop laminarin in the world, and now it has been successfully applied to the treatment of cancer. China's emerging team, Kunbu Health Center, is also developing kelp polysaccharide (Kunbu polysaccharide) belonging to China.

With the progress of science, laminarin will be known by more people.
