Nonetheless, further clinical research is needed to understand the implications of nattokinase dietary supplements and their safety and efficacy. It is recommended to consult a healthcare provider before adding it to your daily routine.

What is Nattokinase?

Nattokinase is an enzyme produced by the fermentation of soybeans by the bacterium Bacillus subtilis natto. It is a fibrinolytic enzyme, which means that it can break down fibrin, a protein that plays a role in blood clotting. Nattokinase is found in natto, a traditional fermented soy food from Japan.

How Does Nattokinase Work?

Nattokinase works by breaking down fibrin, a protein that plays a role in blood clotting. Fibrin is a mesh-like substance that forms when blood clots. Nattokinase can break down fibrin by activating plasminogen, another protein that is involved in blood clot breakdown.

In addition to breaking down fibrin, research indicates that nattokinase can also inhibit the production of plasminogen activator inhibitor-1 (PAI-1), a protein that inhibits plasminogen activation. By inhibiting PAI-1, nattokinase can help to increase the amount of plasminogen that is available to break down fibrin.

Nattokinase is also thought to have other effects that may contribute to its health benefits. For example, nattokinase has been shown to increase blood flow, reduce inflammation, and protect against damage to blood vessels.

Overall, nattokinase is a natural enzyme that has a number of potential health benefits. 

Health Benefits of Nattokinase

Nattokinase has been shown to have a number of potential health benefits, including:

• Reduced risk of blood clots: Nattokinase can break down fibrin, which can help to prevent the formation of blood clots. Blood clots can lead to serious health problems such as heart attack and stroke.
• Improved blood circulation: Nattokinase can help to improve circulatory health by breaking down fibrin and other proteins that can obstruct blood flow. This can help to reduce symptoms such as varicose veins, leg cramps, and cold hands and feet.
• Improved heart health: Nattokinase may help to support cardiovascular health by reducing the risk of blood clots and improving blood circulation. This can help to reduce the risk of heart attack, stroke, and other heart problems.
• Other potential benefits: Nattokinase has also been shown to have potential benefits for other conditions, such as high blood pressure, high cholesterol, and Alzheimer’s disease. However, more research is needed to confirm these findings.

It is important to note that there is limited scientific evidence to support the claims about the health benefits of nattokinase. More research is needed to confirm these findings. It is also important to talk to your doctor before taking any new dietary supplement, especially if you have any underlying health conditions.

Nattokinase Side Effects:

Since nattokinase is a derivative of soybeans, nattokinase is presumed to be safe for most individuals. For instance, a  safety study found that taking nattokinase is of low toxicological concern.

But that doesn’t mean that nattokinase is free of all safety concerns.

Since nattokinase can influence blood circulation and chemistry, it should be used with caution by certain individuals, namely:

• Individuals with bleeding disorders – such as hemophilia, in whom nattokinase may make symptoms worse.
• Individuals who take blood thinning medication – including warfarin, in whom nattokinase may promote bleeding and easy bruising.
• Individuals with low blood pressure – nattokinase may cause lightheadedness, headaches, dizziness, and fainting.
• Individuals on antihypertensive drugs – these include ACE inhibitors and calcium channel blockers, in whom nattokinase may intensify the drug’s effect, triggering hypotension.

To minimize the risk of excessive bleeding, nattokinase should also be halted at least two weeks before a scheduled surgery.

Nattokinase should not be taken by children or during pregnancy or breastfeeding because of the lack of safety data.
