Nattokinase and the Human Blood System

There are many things that affect the blood system, and many things that can go wrong with the rest of the body, as a result of hypercoagulation, high blood pressure and thin blood (just to name a few common problems). Most of these problems are traditionally treated by using dangerous NSAID’s (Non Steroidal Anti-Inflammatory Drugs), like aspirin and ibuprofen.

But there is a dark side to these medicines, that your doctor probably never told you. And that is that these drugs, when used over a long period, can actually make your symptoms worse. They can also cause severe side effects, which are often irreversible.

Take aspirin for example. It is one of the most common pain relief pills available, and commonly used to prevent a heart attack or a secondary heart attack, after suffering a myocardial infarction. But it comes with a fairly long list of side effects.

  • Heartburn
  • Stomach cramps
  • Excess stomach acid secretion
  • Inflammation of the intestines
  • Drowsiness
  • Headaches (ironically, as people have previously used aspirin to treat a headache)

Other, more serious side-effects of aspirin which require immediate medical assistance.

  • Black stools
  • Coughing up blood
  • Fever lasting more than a few days and no reason for it
  • Severe vomiting
  • Ringing in ears/hearing problems
  • Swelling that just won’t go down

Nattokinase does not have these nasty side effects, in fact, it has no known side effects. We are not suggesting that you stop taking aspirin to replace it with nattokinase, that is a decision for you to make WITH your doctor. But, what we would like to do is tell you how nattokinase has helped me, and how it can help reduce blood pressure, dissolve fibroids in women and help with blood clotting problems and poor circulation.

Blood Pressure

Traditional treatments for hypertension are beta blockers, renin inhibitors, diuretics and calcium channel blockers. Yes, they work, and work very well in most cases. But like aspirin, they too are tag-teamed with multiple dangers. Nattokinase does not come with these types of worries, the only thing you need worry about with this enzyme is that if you are taking blood thinning medication, like warfarin, then taking nattokinase is on top, is not wise.

‘Thinning’ your blood too much is very risky. In fact, its dangerous. You can bruise very easily, you can get bleeding gums, frequent nose bleeds and in serious cases, vomiting blood. But if you don’t use blood thinners, trying nattokinase is recommended for high blood pressure.

Blood Clotting

Hypercoagulation, or thickening of the blood is quite common in todays society, and is responsible for causing blocked arteries, which lead to blod clots, DVT’s, heart attacks and even heart failure (death). By taking nattokinase every day, the blood stays at a normal viscosity, helping to protect against heart disease. The enzyme does a great job of breaking down the extra fibrin that is formed in the blood, much in the same way it attacks cancer cells.


Striking any part of the body, at any time, cancer is the worlds leading medical killer. There are two types of cancer – malignant tumors and benign tumors. A malignant tumor is usually a death sentence (as research expands, more and more is being found out about these tumors and there is hope that one day there will be a cure), but a benign tumor can be dealt with by numerous treatments, which usually result in a return to normal health.

Nattokinase, as we’ve just discussed, thins the blood. When the blood is ‘thin’, more oxygen is transported around the body. Oxygen is starved from the ‘infected’ area by cancer cells, so the more oxygen that lives in the blood, the better it is for the cancer patient, protecting the organ from attack.


Many thousands of women each year contract fibroids. And usually they don’t even know about it. There are normally no symptoms (in most patients), but when problems get worse, infertility, frequent urination, heavy bleeding and cramps during period and pregnancy problems, are worst case scenario symptoms. The regular treatment is hormonal therapies which alter the woman’s hormone levels. The worst cases are treated with contraceptive pills and anti-inflammatories (which can have very bad side effects).

Fortunately, nattokinase has already come to the rescue of many women who have had fibroids. Not only has nattokinase CURED their condition, so they don’t get heavy bleeding and cramping any more, but they have been able to conceive for a baby.
