Nattokinase is a natural enzyme extracted from natto — a fermented soybean food eaten in Japan for over 1,000 years. It belongs to a family of "fibrinolytic" enzymes, meaning it supports the body's normal breakdown of fibrin, a protein involved in healthy blood flow and clot balance. The body's own clot-dissolving activity tends to decline as we age, which is why many adults look to nattokinase to support healthy circulation and normal blood flow.
Ours delivers 10,000 FU of enzyme activity per serving — FU (fibrinolytic units) measure how active the enzyme is, which matters far more than milligrams alone.

Nattokinase is generally well-tolerated and has a long history of dietary use. Because it supports healthy blood flow, if you take blood-thinning medication, have a bleeding disorder, or are scheduled for surgery, talk to your doctor before use. Not intended for pregnant or nursing women. Contains soy (from natto). Made in a GMP-certified facility.

What makes Rootwella nattokinase different?
Three things: a high 10,000 FU potency, a real Japanese natto source, and third-party testing for actual enzyme activity — so the potency on the label is what's in the bottle. Many products can't say all three.
What is nattokinase and what does it do?
Nattokinase is a natural enzyme from fermented soybeans (natto). It's a "fibrinolytic" enzyme that supports the body's normal fibrin balance, which is part of healthy circulation and normal blood flow.
What does "10,000 FU" mean?
FU = fibrinolytic units, a measure of enzyme activity. It's the number that actually matters for nattokinase — milligrams alone don't tell you how active the enzyme is. 10,000 FU is a high-potency serving.
How long until I notice anything?
Everyone's different. Nattokinase is best used consistently — give it 4–8 weeks as part of a daily routine. That's why our guarantee runs a full 90 days.
How do I take it?
Three vegetarian capsules daily with water, with or without food. Morning or evening — just be consistent.
Are there any side effects?
Nattokinase is generally well-tolerated. Because it supports healthy blood flow, consult your doctor before use if you take blood thinners, have a bleeding disorder, or have surgery scheduled. Contains soy (from natto).

What Sets Our Nattokinase Apart?
High, Honest Potency (10,000 FU)
Nattokinase is measured in fibrinolytic units (FU), a measure of enzyme activity, not weight. We deliver 10,000 FU per serving, a high-potency dose, and we tell you exactly what's in every capsule instead of hiding behind milligrams.
Real Japanese Natto Source
Our nattokinase comes from authentic Japanese natto, where the fermentation tradition and quality controls behind this enzyme were established. Not a vague, generic source.
3rd-Party Tested for Enzyme Activity
Here's the industry's dirty secret: independent testing has found many nattokinase products deliver less enzyme activity than their label claims. We third-party test for actual FU activity, so the potency on the label is the potency in the bottle.
Customer-First Guarantee
Circulation support builds over time. That's why we back every bottle with a 90-day money-back promise, genuinely enough time to feel the difference.
