Additionally, it helps dissolve cholesterol, dislodge blood clots, and remove calcium crystals from blood vessels, which in turn improves cerebral blood circulation, helping individuals sleep more soundly. Nattokinase was first discovered by Japanese scientists in 2007. With research in this field, two Japanese and American scientists received the Nobel Prize. Today, Nattokinase is widely used in medicine worldwide.
