The Science Behind It

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.

Frequently asked questions

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).

Healthy Inflammation Response

Ancient Japanese Solution for Healthy Arterial Inflammation

Extracted from traditional Japanese natto, our clinical 10,000 FU dose of nattokinase delivers the fibrin-dissolving enzyme your body can no longer produce

Your Blood Pressure Drops Naturally

By boosting nitric oxide production, nattokinase restores your arterial walls inflammation ability to relax and expand naturally - your blood pressure stay in healthly range on its own and you can finally stop worrying about the next doctor's visit

Trapped Cholesterol Gets Released

Nattokinase frees oxidized LDL cholesterol that's been stuck in your arterial walls for years, reducing the "bad" cholesterol deposits causing stiffness and restricting blood flow.

Existing Plaque Begins to Shrink

Years of accumulated deposits start breaking down as the fibrin mesh holding them together dissolves - physically widening your vessels and reversing arterial damage so blood flows freely again

Dangerous Clots Stop Forming

Nattokinase continuously dissolves excess fibrin before clots can develop - giving you 24/7 protection so you can travel, exercise, and live without constant fear of a heart attack.

What Real Customers Are Saying

I've had cold hands and feet for as long as I can remember, my husband jokes I've got ice cubes for feet. I'd honestly just accepted it. Tried a couple of circulation things over the years, a garlic one and a ginkgo one, and felt nothing, so I nearly didn't bother with this. But about three weeks in I noticed I'd stopped putting socks on to go to bed, which never happens. It's not some overnight miracle and I won't pretend it is, but my hands feel warmer through the day and I feel a bit more with it. I've reordered

I'll be honest, I'm a sceptic with these things, got a cupboard full of supplements that did nothing. My daughter got me onto this after I kept moaning about cold feet and feeling sluggish. Wasn't expecting much. Six weeks in now. I'm not going to tell you I feel 25 again, but my feet aren't freezing the way they were and I feel a bit sharper day to day. Three capsules is a fair bit to take at once, I have them with breakfast. For the money, I'll keep going.

The afternoons had really started to drag for me, I'd grind to a halt around 2 or 3 and not want to move. A friend from my walking group kept going on about nattokinase so I gave it a go mostly to keep her quiet. I've been taking it about two months. I can't say every single day is different, some are better than others, but overall I've got a bit more go in me and my feet aren't as cold in the evenings. Easy to swallow, no aftertaste, which I care about. Quietly impressed.

Still fairly active, walk the dog, bit of golf but I'd noticed my hands going cold and just not having the same steady energy through the day. I read up a fair amount and this one had the higher FU, which is what sold me, since apparently a lot of them are underdosed. Couple of months in and I do think my circulation feels better and I'm not flagging as much in the afternoons. Can't speak to anything going on inside, obviously, but I feel good taking it. No complaints.
