01
Backed by Clinical Research
There's a lot of B.S. on the internet. Toku Flow is built on real science: its key ingredients, nattokinase and vitamin K2, were studied in a 12-month clinical trial of more than 1,000 participants. Each serving delivers 10,800 FU of nattokinase (a measure of enzyme activity) plus K2.

Takes 30 Seconds (And It's Delicious)
If it didn't taste great, you wouldn't stick with it. Toku Flow is rich and chocolatey — no chugging seven pills to get the benefits.
03
Rooted in Ancient Tradition
Japan has among the lowest rates of heart disease in the world, and natto (a traditional fermented food packed with nattokinase) has been part of the Japanese diet for centuries.
That's the tradition Toku Flow is built on.
04
A Holistic Approach
Toku Flow combines clinically studied nattokinase, oat beta-glucan, and vitamin K2 to support multiple aspects of cardiovascular health (including healthy cholesterol, blood flow, blood pressure, and arterial health)*.

“I started taking Toku Flow about 2.5 months ago. My cholesterol #'s were increasing and i was worried i would end up on a statin which i didn't want to do. I recently took my blood tests and showed incredible improvement in almost all heart biomarkers!!! Some of my markers improved by over 30% which is wild in such a short period of time.”

“I woke up one day with chronic leg, feet, and toe pain. After an injury to my legs years ago I have suspected poor circulation. I know I have arthritis in my hips. I saw the ad for Toku Flow and decided to give it a try. I am on my second month and I can say there is great improvement. Only thing different I did was take this product. I will continue to take Toku Flow.”
