To those of you taking nattokinase, what dosage are you taking per day?
I would also like to know. I would also like to see some science that backs up what dose might actually work. Is 2000 FU enough? Is it better to take serrapeptase with nattokinase at the same time? How long should you be taking it? So many questions...we need some science based answers! More on reddit.com

February 4, 2023Management of atherosclerosis with 10,800 FU of Nattokinase
Wow, that's interesting. Both hypertension and atherosclerosis are really dangerous, and kill so many people. There's also no currently known medicine that reverses atherosclerosis. So if nattokinase not only treats hypertension, but also reverses atherosclerosis, wouldn't that make it absolutely revolutionary? Why isn't it popular now, since the study is from 2022? I wonder if there's a catch or something. More on reddit.com

August 1, 2025Is 10,800 FU of nattokinase safe?
Yes, based on available clinical evidence. In the Chen 2022 study, 1,062 participants took 10,800 FU per day for 12 months with no serious adverse events reported. However, nattokinase should not be combined with anticoagulant medications, and you should consult your doctor before starting any new supplement regimen.

Nattokinase Dosage Guide: Why 2,000 FU Falls Short – Toku
Is 2,000 FU of nattokinase enough?
For blood pressure support and general fibrinolytic activity, 2,000 FU daily is well-supported by randomized controlled trials. However, a 3-year RCT found that 2,000 FU was not sufficient to slow atherosclerosis progression. Whether 2,000 FU is "enough" depends on your specific health goal — it is effective for some outcomes but may be insufficient for others.

Nattokinase Dose Per Day: Evidence-Based Guide – Naturacare
What is the difference between FU and mg in nattokinase?
FU (Fibrinolytic Units) measure nattokinase's enzyme activity — how effectively it dissolves fibrin clots. Milligrams measure weight. The approximate conversion is 2,000 FU per 100 mg, but this varies by manufacturer. FU is the clinically meaningful metric. A product that only lists milligrams without specifying FU does not provide enough information to assess its potency. Look for products with FU clearly stated on the label.

Nattokinase 10,800 FU - Enteric Coated – Therexa Institute
Nattokinase 10,800 FU - Enteric Coated - Most nattokinase never makes it past your stomach. Here’s why that matters.
Nattokinase is a fibrinolytic enzyme from fermented soybeans, traditionally used in Japan to support cardiovascular and circulatory health. But enzymes are fragile. Stomach acid breaks them down before they can enter the bloodstream, where research shows they actually do their work. Take nattokinase with food or in a standard capsule, and most of the enzyme may be destroyed before it ever reaches the small intestine.
The dose only matters if the delivery works. The landmark 2022 cardiovascular study used 10,800 FU per

Nattokinase Supplement (4000 FU) | Double Wood Supplements
Nattokinase Supplement - Nattokinase is a serine protease enzyme isolated from natto, a traditional Japanese food made from fermented soybeans. Dr. Hiroyuki Sumi discovered it in 1980 while screening clot-degrading compounds. Unlike most cardiovascular supplements that work upstream by improving vessel dilation or reducing inflammation, nattokinase works downstream through a process called fibrinolysis. It breaks down fibrin, the protein mesh that holds blood clots together. It also appears to inactivate plasminogen activator inhibitor-1 (PAI-1), the body’s own brake on clot dissolution.Clinical research has shown nat

Effective management of atherosclerosis progress and hyperlipidemia with nattokinase: A clinical study with 1,062 participants - PMC
Nattokinase (NK), known as a potent fibrinolytic and antithrombotic agent, has been shown to have antiatherosclerotic and lipid-lowering effects. However, data on human clinical studies are limited. In this clinical study involving 1,062 participants, our objective was to examine the efficacy of NK in atherosclerosis and hyperlipidemia and safety at the dose of 10,800 FU/day after 12 months of oral administration.
