Fu is a commonly used unit to commemorate a scientist named ibuprofen, but it is rarely used now.
Nattokinase (NK) is a protein kinase of Bacillus subtilis and a serine protease produced by Bacillus natto during natto fermentation. It has the functions of dissolving thrombus, reducing blood viscosity, improving blood circulation, softening and increasing blood vessel elasticity.
International standard content identifier
20 10, 10, the world's authoritative nattokinase organization-Japan Nattokinase Association and the patent owner of nattokinase-Japan Institute of Life Sciences invited China National Medical Education Development Center to hold a press conference in Beijing Media Center, and issued a statement: Japan Institute of Life Sciences is the largest nattokinase raw material manufacturer in Japan and even the world, with the only nattokinase production patent (patent number) granted by Japan Patent Office. The nattokinase developed in this study is produced by fermentation of Bacillus natto culture solution and extracted and purified by special technology and process. The high-purity nattokinase product made of this material has the function of dissolving thrombus and is a high-tech product in the field of modern biology. Its safety and effectiveness have been verified by medical clinic and fully recognized by Japan Nattokinase Association. In addition, the standard unit of nattokinase products formulated by Japan's official health and nutrition food association is "FU", not "IU".
The difference between FU and FU/g
The international standard unit of nattokinase is "FU", which refers to the nattokinase content of each nattokinase product; "FU/g" refers to the content of nattokinase per gram of natto raw material, and there is a difference between them.
