The World’s #1 Killer

You’re not alone. Cardiovascular disease kills 17.9 million people each year — that’s 1 in every 3 deaths worldwide. In the U.S, someone has a heart attack every 40 seconds.

Not to alarm you, but the real danger is silent cholesterol buildup inside your arteries — until it’s too late. Our formula was developed to help you fight back and stay ahead of stroke, heart attack, and dangerous blood clots.

What’s causing heart attacks, strokes, and blood clots?

It all begins with plaque buildup in your arteries.

Over time, fibrin and cholesterol build up and harden, narrowing your arteries and choking blood flow.

This raises your blood pressure, starves your organs of oxygen — and worst of all — creates the perfect conditions for a deadly clot.

🩸 When a clot breaks loose, it can block blood to your brain (stroke) or heart (heart attack) in seconds.

Most people never see it coming. That’s why prevention is critical — and why Nattokinase is trusted by thousands to support healthy circulation and clear arteries before disaster strikes.

Cholesterol Support

Monacolin K is a naturally occurring compound found in red yeast rice, a traditional Chinese food made by fermenting rice with the yeast Monascus purpureus. Structurally and functionally, monacolin K is identical to lovastatin, a prescription statin drug. It works by inhibiting an enzyme in the liver called HMG-CoA reductase, which plays a key role in producing cholesterol. By blocking this enzyme, the body reduces its internal cholesterol production, leading to a drop in overall blood cholesterol levels, particularly LDL (low-density lipoprotein), often referred to as "bad" cholesterol.

This reduction in LDL cholesterol helps prevent the buildup of plaque in the arteries, which is a major contributor to atherosclerosis and cardiovascular disease. Monacolin K has been shown in multiple studies to effectively lower LDL cholesterol by 20–30% when taken consistently at therapeutic doses. Because it mimics the action of statins, it offers a natural alternative for individuals looking to manage their cholesterol levels without prescription medications, although it should still be used with caution due to similar potential side effects, including muscle pain and liver enzyme elevation.

The Results Speak for Themselves

Lowering LDL cholesterol with monacolin K can have a significant impact on reducing the risk of heart attacks and strokes. High LDL cholesterol contributes to the formation of plaque in the arteries—a condition known as atherosclerosis. Over time, this plaque can narrow or block blood flow to the heart or brain, leading to heart attacks or strokes. By reducing LDL levels, monacolin K helps slow down or even reverse this buildup, keeping arteries clearer and improving overall blood flow. This means the heart doesn’t have to work as hard, and the risk of sudden cardiovascular events is greatly reduced.

Long-term, this cholesterol-lowering effect can contribute to better heart health, fewer hospitalisations, and lower mortality from cardiovascular disease—the leading cause of death globally. In fact, large-scale studies on statins (which monacolin K mimics) show that for every 1 mmol/L drop in LDL cholesterol, the risk of major cardiovascular events can be reduced by around 20–25%. That translates into fewer heart attacks, strokes, and even deaths, especially in people with existing risk factors like high blood pressure, diabetes, or a family history of heart disease.

Why people are moving from the big brands

Sourcing

We source our Nattokinase from non-GMO soy fermented using traditional Japanese methods — the way it’s been done for over 1,000 years. No synthetic enzymes. No shortcuts. Just nature, perfected by time.

Making

Our enzyme is extracted using low-heat precision techniques that preserve its biological activity. Many cheap brands destroy the very thing that makes Nattokinase work. Ours is lab-tested for purity and potency — every single batch.

Formulas

Every batch of our Nattokinase is independently tested by SORA Laboratories to confirm identity, potency, and purity. While most brands never verify what’s in the bottle, we provide third-party proof that you’re getting exactly what the label promises — and nothing you don’t.

At Natural Foundation Supplements, we believe in the long-term benefits of Cholesterol Support and Nattokinase which typically takes several months of consistent use to deliver its full effects. However, we understand that everyone’s experience is unique. That’s why we offer a 30-day satisfaction guarantee—if you're not completely satisfied with your purchase within the first 30 days, just reach out and we’ll provide a full refund. Your health and satisfaction are our top priorities.

Questions? We've Got You Covered!

How long does it take to see results?

The time it takes to see results from taking nattokinase can vary depending on the individual and the reason for taking it. Some people report improved circulation, reduced blood pressure, or relief from symptoms like swelling or heaviness in the legs within a few days to a couple of weeks. 

However, for long-term cardiovascular benefits, it may take several weeks to a few months of consistent use. The studies showing results breaking down artery plaque were over a 6-12 month period. For this reason we offer very generous quantity based discounts for larger quantities. 

What is Nattokinase

Nattokinase is a natural enzyme extracted from natto, a traditional Japanese food made by fermenting soybeans with Bacillus subtilis bacteria. It is known for its ability to break down fibrin, a protein involved in blood clotting, which gives it potential cardiovascular benefits such as supporting healthy blood flow and reducing the risk of blood clots. 

People often take nattokinase as a dietary supplement to help maintain heart health, manage blood pressure, and promote circulation. Unlike some blood-thinning medications, nattokinase is considered a more natural option.

Are there any side effects?

Nattokinase is generally considered safe for most people when taken in appropriate doses, but it can have side effects, especially for those with certain health conditions or who are taking medications. As a potent blood thinner, it may increase the risk of bleeding, particularly if combined with other anticoagulants like aspirin, warfarin, or supplements like fish oil. Some people may experience mild side effects such as stomach discomfort, nausea, or headaches. It's also not recommended for people with bleeding disorders, upcoming surgery, or for pregnant and breastfeeding women without medical supervision. Always consult a healthcare provider before starting nattokinase, especially if you're on medication or have underlying conditions.

Can I take Nattokinase with my current medication?

Always consult a healthcare provider before starting nattokinase, especially if you're on medication or have underlying conditions.

Is Nattokinase safe for long-term use?

Yes, natto is generally considered safe for long-term use when eaten as a food, especially as part of a traditional Japanese diet. It's a fermented soybean product rich in probiotics, vitamin K2, and nattokinase, which may support heart and bone health. However, due to its blood-thinning effects from nattokinase and high vitamin K2 content, people on blood thinners (like warfarin) should be cautious, as it can interfere with medication. For most healthy individuals, regularly eating natto as part of a balanced diet is safe and may even offer long-term health benefits. As always, moderation is key, and it’s a good idea to check with a healthcare provider if you have any specific health concerns.

How long does shipping take?

We dispatch all orders the same day or the next working day. Shipping typically takes 1–3 working days, depending on the shipping option you select at checkout.

How should I take Nattokinase?

Take 1 tablet per day on an empty stomach.
