39.1%

Improvement in coronary plaque health

(measured by coronary plaque score)

25%

Improvement in carotid artery flexibility

(measured by CCA-IMT)

17.6%

Reduction in total cholesterol

16.5%

Reduction in triglycerides

INGREDIENTS

Nattokinase

Known for its potent ability to support healthy blood flow and promote vibrant circulation.*

Vitamin K2 (MK-7)

Plays a vital role in heart and bone health. It helps direct calcium to where it’s needed—your bones and teeth—while helping prevent it from accumulating in the arteries*

Beta Glucan from Organic Oat Bran

Daily supplementation with beta glucan may support a healthy immune system, balanced blood sugar levels and promote digestive health*

EDUCATION

The Truth About Heart Disease

Heart disease can often start with endothelial damage—the breakdown of the thin lining inside our blood vessels. This damage can often be driven by metabolic dysfunction, oxidative stress, and chronic inflammation from poor diets, sedentary habits, environmental factors and more.*

Toku Flow supports a healthy endothelial lining by promoting clear, efficient blood flow—delivering vital nutrients to your heart and organs, and helping your body remove metabolic waste for sustained vitality.*

EDUCATION

Breaking Down The Blood Clot

Nattokinase is an enzyme derived from natto, a fermented soybean dish, which has been a staple in Japan for over a thousand years.

While cardiovascular disease is the leading cause of death in most developed nations, Japan and South Korea stand out with lower rates. Their diets, rich in fermented foods like natto and kimchi, may contribute to better heart health by improving blood flow and reducing clot formation​.

Discovered in the 1980s by Dr. Hiroyuki Sumi for its potent ability to break down blood clots, it works by targeting fibrin—the key protein involved in clot formation.

Frequently Asked Questions

Why not just take nattokinase?

While nattokinase itself has amazing benefits, many nattokinase supplements are underdosed, requiring you to take up to five servings (or even more) to reach clinically relevant levels. With Toku Flow, you're getting a full clinically relevant dose in one convenient serving, making it far more cost-effective compared to leading brands.

Additionally, we've included Vitamin K2 in its most effective form of MK-7, which has proven clinical synergy with nattokinase for enhanced cardiovascular support and organic oat bran rich in beta-glucan, known to improve enzyme absorption and help regulate blood glucose.

We also avoid undisclosed fillers, a widespread issue in the market, by using our proprietary freeze-drying process to isolate the enzyme cleanly and effectively.

And lastly, each of our servings is individually wrapped to maintain the highest possible potency right until consumption, ensuring you're always getting optimal freshness and efficacy. 

How is Toku soy free?

Traditional nattokinase is indeed extracted from natto, which is fermented soybeans. However, the active enzyme itself (nattokinase) can also be produced through fermentation using other legumes. At Toku, we use a specialized fermentation process with chickpeas instead of soybeans, allowing us to deliver pure, soy-free nattokinase. This provides all the cardiovascular benefits without the potential allergenicity of soy.

Can’t I just eat natto?

You absolutely can! We highly recommend eating a whole-food diet as your primary strategy in preventing heart disease. We created Toku Flow as a delicious, easy-to-use supplement to complement and enhance your health journey. The average serving of natto contains around 1,400–2,000 FU of nattokinase, while Toku Flow provides 10,800 FU per serving, ensuring you achieve a clinically relevant dose and experience even greater benefits alongside your dietary choices.

Why Vitamin K2 MK-7?

Vitamin K2 MK-7 (menaquinone-7) is a highly bioavailable form of vitamin K2, naturally found in fermented foods like natto. It’s especially important for heart health because it plays a critical role in calcium metabolism, helping direct calcium to the bones and teeth rather than allowing it to build up in arteries and soft tissues. Clinical studies have shown that regular intake of Vitamin K2 MK-7 supports arterial flexibility, reduces arterial stiffness, and promotes overall cardiovascular health. By pairing Vitamin K2 MK-7 with nattokinase in Toku Flow, we enhance the cardiovascular benefits, providing synergistic support for a healthier heart.

Why Oat Beta-Glucan?

Organic oat bran is the outer layer of whole oat grains, which is naturally rich in dietary fiber, particularly beta-glucan. Beta-glucan is a type of soluble fiber well-known for its heart health benefits. Clinical studies have shown that beta-glucan helps reduce cholesterol levels by binding to cholesterol in the digestive system, facilitating its elimination from the body. It also assists in stabilizing blood sugar levels by slowing glucose absorption, which supports metabolic health. In Toku Flow, we include organic oat bran because beta-glucan not only enhances the absorption of our nattokinase enzyme but also provides these significant cardiovascular and metabolic health benefits, offering comprehensive support for overall heart health.

Can I take Toku Flow alongside prescription medications or other supplements?

Generally, yes, but always consult with your healthcare provider, especially if you're on blood thinning medications or have existing health concerns.

Incredible product – exactly what I’ve been looking for!

I ordered Toku specifically for its focus on cardiovascular health — and it absolutely delivers.

As someone who trains hard and wants to optimize heart health now—not decades from now—this product just made sense. Within days I noticed better circulation, less fatigue during workouts, and better energy. Love that they use science-backed doses and keep the formula clean. Bonus, it tastes awesome too! This is now a staple in my stack and im excited to see its impacts on my next round of bloodwork.

Tastes great and excited to see how it works for me

I just started using Flow and was honestly surprised by how good it tastes. It has a rich, chocolatey flavor that makes it really easy to enjoy every day. I'm excited to see how it supports my energy, focus, and circulation over time. It’s great to have a supplement that fits into my routine without feeling like a chore.

The best nattokinase brand I've tried

I've been taking nattokinase for a few months now and have tried other brands on the market but they've all been pills. I hate taking pills, so I've never really been consistent. I was so happy to see that such a great supplement is now available in drink form. It makes it SO much easier, just throw it in my coffee in the morning and I'm good to go. It gives my coffee a nice chocolatey flavor too!

Game changer for blood pressure and nerve pain!

I've been taking Toku Flow for about 6 months as part of their pre-launch trial group and have seen my systolic blood pressure normalize (dropped by about 10 points on average) and my triglycerides went from 92 to 60 in about 3 months of consistently taking it.

I've also noticed that the nerve pain I typically have from a lumbar disc herniation is much milder than normal and seemed to get worse when I forgot to take it with me on vacation for several days in a row. Game changer all around!

Great Taste

just got my 90 days supply to Toku Flow which I'm taking to improve my lipid panels across the board vs. using statins and other supplements. So far, the flavor is fantastic and can't wait to see the results when I retake my blood tests in 60 days. I mix it with cold water and it tastes like chocolate milk. Great tasting!
