Can Nattokinase Clean Clogged Arteries?

Can Nattokinase Clean Clogged Arteries?

The arteries are a passageway that carries blood away from the heart. These passageways have a series of valves regulating blood flow that flows in and out of your body. 

While the arterial system is designed for efficient blood flow, it can still be prone to blockages that cause the arteries to become clogged with plaque build-up. 

Nattokinase (NK) is a protein found in soybeans that has been used as an effective means of opening up blocked arteries. Here, we’ll explore whether nattokinase can effectively clean our arteries.

Nattokinase is a protein that can help break down and dissolve plaque build-up in clogged arteries. It’s been shown to reduce arterial wall thickness by up to 36.6 percent over six months.

human study was conducted to determine if nattokinase could, in fact, clean arteries. The researchers even tested it against a potent prescription drug (Simvastatin) used explicitly for clogged arteries.

The study involved 82 people, of which 76 completed the entire experiment that lasted six months.

The results showed that nattokinase was significantly more effective at removing plaque from the arteries (36.6 % for NK vs. 11.5% for Simvastatin)

Numerous animal studies have shown that nattokinase is a potent anti-atherosclerotic (help to clean arteries of plaque). Researchers believe that NK is able to clean arteries because it can inhibit low-density lipoprotein (LDL) oxidation.

High levels of LDL, “the bad cholesterol,” is a significant factor of plaque build-up in your arteries. Anything that can stop or control LDL build-up will keep your arteries healthy and optimized. NK appears to do just that.

Japan is known for eating natto as a staple food in its diet. Interestingly, studies conducted on thousands of Japanese people show that natto protects them from all-around cardiovascular diseases.

Is Nattokinase Safe To Use?

Scientists have determined that nattokinase is safe for humans from studies already conducted. NK is used around the world as a nutritional supplement for blood circulation and blood clotting problems.

In another human study that included healthy people, patients with cardiovascular problems, and patients undergoing dialysis, they were given 2 capsules of 2000 FU daily for two months. They experience no health issues whatsoever.

If you are on blood-thinning or blot-clot medication, consult your doctor before using it.


There is no exact dosage for nattokinase. But people have taken 100 mg (2000 FU) three times per day with no ill effects.


Nattokinase works by breaking down and removing plaque build-up, which creates an opening for the blocked artery to flow again. 

Research has been conducted on whether nattokinase can clean arteries in humans. And they showed that:

  • Nattokinase can help prevent heart disease. 
  • Research shows that nattokinase can clean arteries in humans.

The benefits of consuming nattokinase will depend on many factors such as age, health history, lifestyle habits, and diet. 

If you would like more information on whether nattokinase is right for you, consult your doctor or speak to a nutritionist before trying it out.
