Nattokinase: History And Health Benefits
Nattokinase is a proteolytic enzyme that naturally occurs in natto. It is a traditional fermented soybean dish and a well-known staple food in Japan. Natto is fairly easy to make since it only requires water, straw and soybeans. The straw that has the bacterium called bacillus subtilis natto will be mixed with the freshly steamed soybean and water. After that, it will be set for fermentation. During fermentation, natto develops its mild taste and it has a very strong odor like that in the blue cheese.
In the year 1980, Dr. Hiroyuki Sumi was looking for a food that can effectively break up blood clots like those that can cause cardiac arrest and stroke. He discovered that natto can dissolve fibrin which is the type of protein that builds up in blood clots. In his laboratory experiment, he discovered that natto has the ability to completely dissolve fibrin clots after almost about 18 hours. Natto is low in cholesterol and it contains high quality protein and an excellent source of vitamin K, copper, iron, magnesium and manganese.
Nattokinase works similarly like blood-thinning agent coumadin. People who have had vascular injury or those people who are in risk of elevated fibrinogen level formation can benefit from the fibrin-digesting effects of nattokinase. It also reduces the thickening of the arteries and helps to heal damaged blood vessels.
What Does "FU" Mean in terms of Nattokinase?
Companies that manufacture nattokinase supplements express its activity in terms of "FU" or fibrin units. This is entirely different from the IU measurement since it only indicates nattokinase activity base on the degradation of fibrin. But as of today, IU is being officially adopted by the Japanese when measuring nattokinase. The FU method doesn't have exact measure of nattokinase activity and is suspected to be erroneous. Because of that, IU standard is being used to accurately measure nattokinase.
However, the FU measurement is still being widely used in labels. Most nattokinase supplements nowadays are in 100 mg capsule with 2,000-4,000 FU. As a precaution, it's best to consult a doctor first before taking nattokinase supplements for appropriate guidance and supervision with regards to its proper usage. Pregnant women including those people who have had stroke before or any other bleeding disorders must not take nattokinase supplements.
