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

What Our Customers Say
Cialis was only working halfway
I'd been taking it for five years, and in 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 pharmacy one was only 2,000. With Silencia, in week three I woke up in the morning like I hadn't in years. The Cialis is in the drawer now.
I thought he didn't want 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 Silencia and I set it out every morning next to his coffee. After a month, he came looking for me. That's all I'll say.
My ankles don't swell in the evening anymore
I've been on amlodipine for three years, and in the evening I had sock marks that wouldn't go away. After ten days of Silencia my ankles were already less swollen. At my checkup my blood pressure had dropped another eight points. My doctor told me to keep going.
My cholesterol dropped without a statin
The statin gave me cramps in my calves, so I quit it. My cholesterol was 268. After three months of Silencia it was 211. My doctor looked at my blood work and asked me what I'd changed.
Finally, the right dose
I'd been taking pharmacy nattokinase for a year, on faith, without feeling anything. 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 week two.
Viagra scared me because of my heart
I have two stents and I take daily aspirin. I didn't dare take Viagra. With Silencia, one capsule at lunch, after a month things in bed were almost back to how they used to be. No pills and no anxiety.
Diabetic for 12 years, I thought it was over
My diabetes doctor said my numbers were fine, but my erections were gone. Nobody had explained that diabetes closes the smallest arteries first. After five weeks of Silencia, my mornings came back. I started believing again.

Why things in bed don't work like they used to
Why it happens
The artery that carries blood to the penis is one to two millimeters wide. The one to your heart is three to four. With age, high blood pressure, cholesterol and diabetes, fibrin builds up inside your arteries. It's a sticky mesh that thickens your blood and traps plaque.
In a wide pipe you don't notice. In a one-millimeter pipe you do. That's why morning erections disappear first, then you go soft during sex, then even the pill only works halfway. The pill pushes blood for a few hours, but it doesn't reopen the pathway.
What Silencia does
Nattokinase is the enzyme from Japanese natto that dissolves fibrin. Your blood flows freely again, and plaque loses the mesh that holds it together. Once the pathway reopens, blood reaches all the way again, and stays there.
Silencia gives you 10,000 FU of nattokinase in a single capsule, plus aged garlic, coenzyme Q10, turmeric, bromelain, pine bark and grape seed.
The proof: a study of 300 heart patients in Milan 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 that your arteries are closing.
Plaque needs a mesh. Nattokinase takes it apart.
Why it happens
Arterial plaque isn't just cholesterol. Cholesterol gets caught in a mesh of fibrin and hardens there. The more mesh, the thicker your blood and the narrower the pathway.
That's why you get swollen ankles in the evening, sock marks, cold hands and feet, and blood pressure that won't come down even with the pill.
What Silencia does
Nattokinase breaks down the fibrin strands. Plaque loses its support and blood flows again. Aged garlic supports your artery walls, coenzyme Q10 fuels your heart, and turmeric and bromelain calm inflammation.
The proof: in a study of 1,062 people, nattokinase at 10,800 FU a day for 12 months reduced 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
In pharmacies, nattokinase is sold at 2,000 FU per capsule. FU are the units that measure how much fibrin the enzyme can dissolve.
In studies, results only came with high doses. At 3,600 FU a day, nothing happened. To reach 10,000 with the pharmacy kind you'd have to take five capsules a day, every day. Nobody does that.
What Silencia does
Here you get 10,000 FU in a single capsule, the study dose, plus six actives for your arteries and heart. One capsule a day with a meal, and that's it.
Most nattokinase stops at 2,000 FU. This one gives you 10,000 FU in a single capsule.
The proof: the FU number 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, with a glass of water. Breakfast or lunch, whatever suits you.
One capsule already holds the full dose: 10,000 FU of nattokinase plus six actives for your arteries and heart. No pill counting.
The exact time doesn't matter. What matters is taking it every day, because fibrin breaks down day after day.
Arteries don't clear overnight. But your blood starts flowing better within 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: more strength and stamina in bed, less swollen ankles, steadier blood pressure.
Month 3 onward: in studies, arterial plaque shrank by more than a third in one year.
We sell direct from the manufacturer to your door, with no distributors, sales agents or pharmacies adding their markup at every step.
To reach 10,000 FU a day with pharmacy nattokinase, you'd need five capsules a day. That means five times the bottles, every single month. Here you get the full dose in one capsule, for less.
There's no catch. Just a shorter supply chain.
You have 90 days to try it risk-free. If you don't feel the difference, we refund your entire order.

Nattokinase from fermented natto, 10,000 FU per capsule. Natto is the fermented soybean dish people in Japan have eaten for breakfast for centuries.
It's combined with aged garlic extract, coenzyme Q10, turmeric, bromelain, pine bark extract and grape seed extract. Plant-based 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. You take it alongside the medication you already use.
Diabetics: yes. Diabetes closes the smallest arteries first, and that's exactly where nattokinase works.
Stents or blood thinners: fine, but talk to your doctor first.
Celiac: yes, it's gluten-free. Pregnancy and breastfeeding: not recommended.
Yes. Fibrin breaks down day after day, and in studies the plaque results came in 6-12 months. You feel the first changes sooner, but arteries need time.

Research-backed benefits
What this nattokinase actually does
Nattokinase dissolves fibrin, the sticky mesh that thickens your blood and holds plaque together. 10,000 FU in one capsule, the dose used in studies, plus 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 this one has 10,000.
Full performance in bed
Full erections, right to the end
The artery that carries blood to the penis is the narrowest in the body, and it's the first to close. Once the fibrin breaks down, blood reaches all the way again. Your mornings come back, and you stop going soft halfway through.
Blood pressure and legs
Less swollen ankles, warm hands and feet
Smoother blood moves better through small vessels. Ankles swell less in the evening, the sock marks disappear, and hands and feet warm up again. Nattokinase and aged garlic also support healthy blood pressure.
Works with your medication
No need to stop anything
Take it alongside your blood pressure pill, your statin and your diabetes medication. The pill lowers the number. Nattokinase works on the arteries underneath.

Stick with it, it's worth it
The first two weeks I felt nothing. By week three my 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 took the 2,000 FU one from the pharmacy for a year, on 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 went down.
My husband came back to me
For two years my husband avoided me, and I thought it was my fault. It was his blood pressure, his arteries. I set one out for him every morning. After a month, he came looking for me. Thank you, truly.

5 reasons why
Why this nattokinase isn't like the others

01

Stories from men who take it every day
“It's just your age.” Then my cardiologist asked me a question.
I'm 63 and I've had high blood pressure for ten years. I take amlodipine and a statin. For two years, things in bed just stopped working. I'd start fine and then go soft. Cialis helped at first, then less and less, and I doubled the dose without telling anyone. My wife thought I didn't find her attractive 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 closes first, years before the heart. That the pill pushes blood but doesn't reopen anything. He told me about nattokinase. At the pharmacy I found it at 2,000 FU, and he told me the studies use 10,000. I found this one. One capsule at lunch. In week three I woke up at six in the morning like I was forty again. After a month, I was the one reaching for her. At my next checkup, my cardiologist looked at my blood work and said: keep doing what you're doing.

Frequently asked questions
What everyone asks us
What makes this nattokinase different from the pharmacy kind?
The dose. Pharmacy nattokinase comes at 2,000 FU per capsule. In studies, 3,600 FU a day did nothing, while 10,800 FU cut plaque by 36% in one year. Here you get 10,000 FU in a single capsule, together with aged garlic, coenzyme Q10, turmeric, bromelain, pine bark and grape seed.
My erection pill doesn't work anymore. Can this help?
The pill pushes blood for a few hours, but if your arteries are closing, the blood only gets halfway. Nattokinase works on the pathway. It dissolves the fibrin that thickens your blood and narrows your arteries. Many of our customers come to us exactly from there, after years of pills that worked less and less.
Can I take it with the medication I'm already on?
Yes, you take it alongside your blood pressure pill, your statin and your diabetes medication, without stopping anything. If you're on blood thinners or daily aspirin, talk to your doctor first, because nattokinase also thins the blood.
How soon will I see the first results?
Lighter legs and warmer hands in the first 1-2 weeks. Morning erections usually come back between week three and week four. The work on plaque continues month after month, and in studies the 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 also 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, with 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 in pharmacies, plus six actives for arteries and heart. For clearer arteries and full performance, every day.
