Niroa® Nattokinase 10,000 FU

  • Breaks Down Fibrin, the Scaffold Plaque Builds On*
  • Supports Healthy Blood Pressure & Cholesterol*
  • Warmer Hands, Lighter Legs — Better Circulation*
  • 10,000 FU — the Clinically Studied Dose

Why Plaque Isn't a Willpower Problem

Plaque doesn't build on cholesterol alone. It builds on fibrin — a protein mesh inside the artery wall that catches cholesterol and holds it there while it hardens. Cut all the red meat you like: if the mesh stays, so does the plaque.

  • Numbers that won't come down no matter what you cut
  • Cold hands and feet, heavy legs on the stairs
  • A statin that stopped the climb but never reversed it
  • That "am I next?" feeling every time a parent comes up

Nattokinase is a fibrinolytic enzyme — it supports your body's natural ability to break down the fibrin mesh that plaque builds on. Not a bandaid over the number. Support for the structure underneath.*

What Makes It Different

Why Our Cardiovascular Formula Works Better

Reason 1

A Clinical-Strength Dose: 10,000 FU

FU measures the enzyme's activity. Typical brands give you 2,000 FU per serving. We formulated at 10,000 FU — more than 5× that — to match the higher intakes used in modern research.*

Reason 2

7-in-1 Formula, Not Just Nattokinase Alone

CoQ10 supports heart energy. Bromelain and turmeric support a healthy inflammation response. Aged garlic supports healthy cholesterol. Pine bark supports arterial flexibility. All in 2 capsules.*

Reason 3

Made With MCT Oil So More Actually Gets Absorbed

Most nattokinase capsules use cheap fillers that sit in your gut and do nothing. Niroa is formulated with MCT oil — a natural fat that helps your body absorb more of the active enzyme into your bloodstream. Less waste. More of what you paid for actually gets to work.*

Reason 4

Third-Party Tested, Every Batch

Labels are easy to print. Proving them is harder. Every batch of Niroa Nattokinase is independently tested for FU potency, purity and safety. We don't ask you to trust a claim we can't back up.

The Numbers Speak For Themselves

What to expect, week by week

Week 1–2

Nothing dramatic — and that's the point

The enzyme starts circulating within hours, but you won't feel a thing yet. That's normal. This isn't caffeine — it's a fibrinolytic enzyme building in your system. Two capsules a day with food. No loading phase, no timing rules. Just consistency. The people who get the most out of Niroa are the ones who stop looking for a miracle and start building the habit.

Week 3–4

The small things change first

This is where it starts — and it has nothing to do with a lab report. Warmer hands and feet, especially at night. Less heaviness in the legs after long days. Steadier, more even daily energy that doesn't crash at 3pm. Most people don't connect it to the capsule right away. Their partner notices before they do — the cold feet in bed stop, the afternoon naps disappear. Small shifts. But real ones.

Week 5–8

You stop thinking about it — because it's working

Easier stairs and less huffing on inclines. Better stamina on daily walks. The afternoon doesn't hit like it used to. This is the window where people stop asking "is it working?" and start forgetting they ever had a problem. Your next blood panel is the one that might catch your doctor's attention — support for your numbers starts showing up on paper.*

Month 3+

You feel what happens when you skip it

Full compound effect. This is what cardiovascular support feels like when it's had time to build. The improvements aren't exciting anymore — they're just how you feel. Most people don't reorder because we remind them. They reorder because they ran out for a week on holiday and felt the heaviness creep back into their legs. That's when you know it's doing its job.

Give it the full 90 days — and if you don't feel a real difference, you're covered by our money-back guarantee.

Frequently Asked Questions

Everything you're wondering, answered honestly.

Niroa is a dietary supplement made from natural ingredients. Many of our customers take it alongside their existing blood pressure or cardiovascular medication. That said, because nattokinase supports healthy fibrin levels, we always recommend checking with your doctor before starting — especially if you're on blood thinners, anticoagulants, or antiplatelet medication. We're not here to replace medical advice — just to give you a clean, natural option to support your body alongside whatever you're already doing.*
FU stands for fibrinolytic units — it measures how active the nattokinase enzyme actually is. Most brands sell 2,000–4,000 FU per serving, which is considered a basic maintenance dose. Clinical research on cardiovascular and arterial health has used doses in the 10,000+ FU range. Niroa delivers the full 10,000 FU per serving so you're not underdosing. You'd need 3–5 capsules of most competing brands to match a single Niroa serving.
It depends on your body, but nattokinase builds with consistent daily use. Most customers report noticing subtle shifts — warmer hands and feet, more even energy — within the first 3–4 weeks. Cardiovascular markers like blood pressure move more slowly, which is exactly why our guarantee runs 90 days. Give it time to compound before you judge.*
Three things: dose, formula, and transparency. Most nattokinase supplements on the market deliver 2,000–4,000 FU — a fraction of the clinical-strength range. Niroa delivers 10,000 FU. We also include six additional cardiovascular support ingredients (CoQ10, bromelain, turmeric, aged garlic extract, and pine bark extract) — not as filler, but because each one supports a different aspect of heart and circulatory health. And every ingredient is listed with its amount. No proprietary blends. No guessing.
Nattokinase has been consumed for over 1,000 years as part of traditional Japanese diets through natto — fermented soybeans. Niroa uses pure, vegetarian capsules with no synthetic fillers or artificial additives. As with any supplement, consult your healthcare provider before starting — particularly if you are pregnant, nursing, scheduled for surgery, or currently on blood-thinning medication.*
Two capsules a day with a meal. Most customers take them in the morning as part of their routine. No loading phase. No complicated timing. Just consistency — that's what makes the difference.
Then you don't pay for it. Niroa comes with a 90-day money-back guarantee — no hoops, no hassle, no questions asked. We give you 90 days because that's how long nattokinase takes to fully compound in your system. Give it an honest try, and if you're not happy for any reason, reach out and we'll refund every penny. All the risk is on us.

90-Day Money-Back Guarantee
