How Flow fits. What makes it different. What to expect from your routine.
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 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.
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.
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.
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.
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 can assist in stabilizing blood sugar levels by slowing glucose absorption, which supports metabolic health. In Toku Flow, we include gluten-free oat bran because beta-glucan not only may enhance the absorption of our nattokinase enzyme but also provides these significant cardiovascular and metabolic health benefits, offering comprehensive support for overall heart health.
Generally, yes, but always consult with your healthcare provider, especially if you're on blood thinning medications or have existing health concerns.
