10,000 FU, the dose used in studies
Drugstore nattokinase comes in at 2,000 FU per capsule. In studies, 3,600 FU a day did nothing. The plaque results came at high doses. Here you get 10,000 FU in a single capsule.

What Our Customers Are Saying
Cialis was only working halfway
I'd been on it for five years, and the last few months I'd start strong and then go soft. I'd already doubled the dose. My cardiologist told me about my arteries and about nattokinase, but the one at the drugstore was only 2,000 FU. With Ardentis, by week three I was waking up in the morning like I hadn't in years. The Cialis is in the drawer now.
I thought he wasn't attracted to me anymore
For two years my husband went to bed before me so he wouldn't have to try. I thought it was my fault. He's had high blood pressure for ten years. I bought him Ardentis and I set it out every morning next to his coffee. A month later, he was the one reaching for me. That's all I'll say.
No more swollen ankles at night
I've been on amlodipine for three years, and every evening I had sock marks that wouldn't go away. After ten days on Ardentis my ankles were already less puffy. At my checkup my blood pressure was down another eight points. My doctor told me to keep doing what I'm doing.
Cholesterol down without a statin
The statin gave me calf cramps that locked my legs up, so I quit it. My cholesterol was 268. After three months on Ardentis it was 211. My doctor looked at the labs and asked me what I'd changed.
Finally, the right dose
I took drugstore nattokinase for a year on blind faith and never felt a thing. Then I read that the studies use 10,000 FU and mine was 2,000. With this one my hands and feet felt warmer by the second week.
Viagra scared me because of my heart
I have two stents and I'm on daily low-dose aspirin. I wasn't comfortable taking Viagra. With Ardentis, one capsule at lunch, after a month things in bed were almost back to how they used to be. No pills, no anxiety.
Diabetic for 12 years, I thought it was over
My endocrinologist said my numbers were fine, but the erections were gone. Nobody ever told me diabetes shuts down the smallest arteries first. After five weeks on Ardentis, the mornings came back. I started believing again.
Nattokinase 10,000 FU · Full Strength in Bed Again, Feel the Difference in 7 Days
Why things don't work in bed like they used to
Why it happens
The artery that carries blood to the penis is one to two millimeters wide. The one that feeds your heart is three to four. With age, high blood pressure, cholesterol and diabetes, fibrin builds up inside your arteries: a sticky web that thickens your blood and holds plaque in place.
In a wide pipe, you don't notice. In a one-millimeter pipe, you do. That's why morning erections disappear first, then you start going soft mid-act, then even the pill only works halfway. The pill pushes blood for a few hours, but it never reopens the passage.
What Ardentis does
Nattokinase is the enzyme from Japanese natto that dissolves fibrin. Your blood flows freely again and plaque loses the web that holds it together. Once the passage opens back up, blood reaches all the way down again, and it stays there.
Ardentis gives you 10,000 FU of nattokinase in a single capsule, plus aged garlic, CoQ10, turmeric, bromelain, pine bark and grape seed.
The proof: a study of 300 heart patients in Milan, Italy found that in 67% of cases, erection problems showed up an average of 38.8 months before the heart problem. Your erection is the first warning sign that your arteries are closing.
Plaque needs a web. Nattokinase tears it down.
Why it happens
Arterial plaque isn't just cholesterol. Cholesterol gets trapped in a web of fibrin and hardens there. The more web there is, the thicker your blood gets and the narrower the passage becomes.
That's where the swollen ankles at night come from, the sock marks, the cold hands and feet, and the blood pressure that won't come down even on medication.
What Ardentis does
Nattokinase breaks apart fibrin strands. Plaque loses its scaffolding and blood flows again. Aged garlic supports your artery walls, CoQ10 fuels your heart, and turmeric and bromelain shut down inflammation.
The proof: in a study of 1,062 people, nattokinase at 10,800 FU a day for 12 months cut carotid plaque by 36% and bad cholesterol by 18%. In another study it reduced plaque by 36.6%, versus 11.5% for a statin.
Why the nattokinase you tried didn't work
Why it happens
Drugstore nattokinase usually comes in at 2,000 FU per capsule. FU are the units that measure how much fibrin the enzyme can dissolve.
In the studies, results only showed up at high doses. At 3,600 FU a day, nothing happened. To reach 10,000 with the drugstore kind, you'd have to take five capsules a day, every day. Nobody does that.
What Ardentis does
Here you get 10,000 FU in a single capsule, the dose used in studies, plus six actives for your arteries and heart. One capsule a day with a meal. That's it.
It's the only nattokinase with 10,000 FU and a full 7-in-1 artery complex in one capsule.
The proof: the FU count is printed on your nattokinase bottle. If it says 2,000, you're getting one fifth of the dose.

One capsule a day with a meal and a glass of water. Breakfast or lunch, whatever works for you.
One capsule already holds the full dose: 10,000 FU of nattokinase plus six actives for your arteries and heart. No counting pills.
The exact time doesn't matter. What matters is taking it every day, because fibrin dissolves day after day.
Your arteries don't clear overnight. But your blood starts flowing more freely in the first few weeks.
Weeks 1-2: lighter legs in the evening, warmer hands and feet.
Weeks 3-4: many men notice their morning erections coming back.
Weeks 5-8: harder and longer-lasting in bed, less ankle swelling, steadier blood pressure.
Month 3 and beyond: in studies, arterial plaque shrank by more than a third in one year.
We sell direct from the manufacturer to your door, skipping the distributors, sales reps and drugstores that each add their markup along the way.
At the drugstore, a 2,000 FU nattokinase costs $12-21. To get to 10,000 FU a day you'd have to buy five times as much: over $60 a month. With us you get the full dose in a single capsule, for less.
There's no catch. Just a shorter supply chain.
You get 90 days to try it risk-free. If you don't notice the difference, we'll refund your entire order.
No need to send the bottle back. We won't ask why. There's no form to fill out.

Nattokinase from fermented natto, 10,000 FU per capsule. Natto is the fermented soybean dish people in Japan have eaten for breakfast for centuries.
Alongside it: aged garlic extract, CoQ10, turmeric, bromelain, pine bark extract and grape seed extract. Veggie capsule, non-GMO, gluten-free.
Made in a GMP-certified facility. Every batch is tested by independent labs for purity, potency and contaminants. Certificates of analysis are available on request.
High blood pressure and cholesterol: yes, it's made for people whose arteries are under strain. Take it alongside the medications you already use.
Diabetics: yes. Diabetes shuts down the smallest arteries first, and that's exactly where nattokinase works.
If you have stents or take blood thinners: it's fine, but talk to your doctor first.
Celiac: yes, it's gluten-free. Pregnancy and breastfeeding: not recommended.
Yes. Fibrin dissolves day after day, and in studies the plaque results came in 6-12 months. You'll feel the first changes sooner, but your arteries need time.

Research-backed benefits
What this nattokinase actually does
Nattokinase dissolves fibrin, the sticky web that thickens your blood and holds plaque together. 10,000 FU in one capsule, the dose used in studies, with six actives for your arteries and heart.
Clearer arteries
Less plaque, smoother blood flow
In studies, 10,800 FU a day for 12 months cut carotid plaque by 36% and bad cholesterol by 18%. At 3,600 FU, nothing happened. That's why there are 10,000 in here.
Full strength in bed
Full erections, all the way to the end
The artery that carries blood to the penis is the narrowest in your body, and it's the first to close. Once the fibrin dissolves, blood reaches all the way down again. The mornings come back, and you stop going soft halfway through.
Blood pressure and legs
Less ankle swelling, warm hands and feet
Thinner blood moves better through small vessels. Your ankles swell less at night, the sock marks disappear, and your hands and feet warm back up. Nattokinase and aged garlic support healthy blood pressure too.
Works with your medications
You don't have to stop anything
Take it alongside your blood pressure pill, your statin and your diabetes meds. The pill lowers the number. Nattokinase works on the arteries underneath.

Frank put the Cialis in the drawer…

I'd been taking it for five years and it was only working halfway. I'd start strong and then go soft. With Ardentis, by week three I was waking up in the morning like I hadn't in years. A month in, I was the one reaching for her, in the middle of the afternoon, no pill.

Stick with it. It's worth it.
The first two weeks I didn't feel a thing. By week three the mornings were back, and by week six things in bed were like ten years ago. I have high blood pressure and Viagra scared me. I take this one at lunch and don't think about it anymore.
Finally, the right dose
I'd been taking the 2,000 FU drugstore kind for a year on blind faith. Nobody told me the studies use 10,000. With this one, after a month my legs felt light, my feet were warm, and my cholesterol came down.
I got my husband back
For two years my husband avoided me and I thought it was my fault. It was his blood pressure. It was his arteries. I set it out for him every morning. A month later, he was the one reaching for me. Thank you, truly.

Stories from men who take it every day
"It's just my age." Then my cardiologist asked me one question.
I'm 63 and I've had high blood pressure for ten years. I take amlodipine and a statin. For two years things just stopped working in bed. I'd start strong and then go soft. Cialis helped at first, then less and less, and I doubled the dose without telling anyone. My wife thought I wasn't attracted to her anymore. I'd pretend to be asleep when she came to bed. At my checkup my cardiologist asked me: do you still wake up with an erection in the morning? I turned red. He explained that the artery to the penis is the narrowest in the body and it closes first, years before the heart. That the pill pushes blood but doesn't reopen anything. He told me about nattokinase. At the drugstore I found it at 2,000 FU, and he told me the studies use 10,000. I found this one. One capsule at lunch. By week three I was waking up at six in the morning like I was forty again. A month in, I was the one reaching for her. At my next checkup my cardiologist looked at my labs and said: keep doing what you're doing.

Frequently asked questions
What everyone asks us
What makes this nattokinase different from the drugstore kind?
The dose. Drugstore nattokinase comes in at 2,000 FU per capsule. In studies, 3,600 FU a day did nothing, while at 10,800 FU plaque shrank by 36% in one year. Here you get 10,000 FU in a single capsule, together with aged garlic, CoQ10, turmeric, bromelain, pine bark and grape seed.
My ED pill doesn't work anymore. Can this help me?
The pill pushes blood for a few hours, but if your arteries are closing, the blood only gets halfway there. Nattokinase works on the passage itself: it dissolves the fibrin that thickens your blood and narrows your arteries. A lot of our customers come to us from exactly there, after years of pills that worked less and less.
Can I take it with the medications I'm already on?
Yes. Take it alongside your blood pressure pill, your statin and your diabetes meds, without stopping anything. If you're on blood thinners or daily low-dose aspirin, talk to your doctor first, because nattokinase also thins the blood.
How soon will I see results?
Lighter legs and warmer hands in the first 1-2 weeks. Morning erections usually come back between weeks three and four. The work on plaque keeps going month after month: in studies, results came in 6-12 months. That's why we recommend at least 90 days.
Does it work even if I don't have problems in bed?
Yes. Nattokinase works on the arteries throughout your whole body. People take it for high cholesterol, high blood pressure, swollen ankles, cold hands and feet, or because a family member had a heart attack.
How do I take it?
One capsule a day with a meal and a glass of water. Breakfast or lunch, whichever you prefer. One capsule already holds the full dose.
One capsule a day. 10,000 FU, the dose used in studies.
Nattokinase from Japanese natto, at a dose you won't find at the drugstore, with six actives for your arteries and heart. For clearer arteries and full strength, every day.
