10,000 FU, the study dose
In pharmacy, nattokinase is dosed at 2,000 FU per capsule. In studies, at 3,600 FU per day, nothing happened: the results on plaque appeared at high doses. Here, you get 10,000 FU in a single capsule.

Ce que disent nos clients
Le Cialis ne faisait plus effet qu'à moitié
Je le prenais depuis cinq ans et, ces derniers mois, je commençais bien puis ça retombait. J'avais déjà doublé la dose. Mon cardiologue m'a parlé des artères et de la nattokinase, mais celle de la pharmacie était à 2 000. Avec Silencia, à la troisième semaine, je me suis réveillé le matin comme ça ne m'était pas arrivé depuis des années. Le Cialis est maintenant au fond du tiroir.
Je pensais qu'il ne me désirait plus
Depuis deux ans, mon mari allait se coucher avant moi pour ne pas avoir à essayer. Moi, je pensais que c'était ma faute. Il a de la tension depuis dix ans. Je lui ai acheté Silencia et je lui prépare sa gélule chaque matin à côté du café. Au bout d'un mois, c'est lui qui est venu vers moi. Je n'en dis pas plus.
Mes chevilles ne gonflent plus le soir
Je prends de l'amlodipine depuis trois ans et, le soir, j'avais la marque des chaussettes qui ne partait pas. Après dix jours de Silencia, mes chevilles avaient déjà dégonflé. Au contrôle, ma tension avait encore baissé de huit points. Le médecin m'a dit de continuer comme ça.
Mon cholestérol a baissé sans statine
La statine me donnait des crampes dans les mollets et je l'ai arrêtée. Mon cholestérol était à 2,68. Après trois mois de Silencia, il était à 2,11. Le médecin a regardé les analyses et m'a demandé ce que j'avais changé.
Enfin la bonne dose
Je prenais la nattokinase de la pharmacie depuis un an, en faisant confiance, sans rien sentir. Puis j'ai lu que les études utilisent 10 000 FU et la mienne était à 2 000. Avec celle-ci, j'ai senti mes mains et mes pieds plus chauds dès la deuxième semaine.
J'avais peur du Viagra pour mon cœur
J'ai deux stents et je prends du Kardégic. Le Viagra, je n'osais pas le prendre. Avec Silencia, une gélule au déjeuner, au bout d'un mois, les choses au lit sont redevenues presque comme avant. Sans comprimés et sans angoisse.
Diabétique depuis 12 ans, je pensais que c'était fini
Mon diabétologue disait que mes chiffres étaient bons, mais l'érection n'était plus là. Personne ne m'avait expliqué que le diabète bouche d'abord les plus petites artères. Après cinq semaines de Silencia, le matin est revenu. J'ai recommencé à y croire.
Nattokinase 10,000 · Get back to peak performance in bed, feel the difference in just 7 days
Pourquoi au lit, ça ne marche plus comme avant
Pourquoi ça arrive
L'artère qui amène le sang au pénis mesure un ou deux millimètres de large. Celle du cœur en mesure trois ou quatre. Avec les années, la tension, le cholestérol et le diabète, de la fibrine se dépose dans les artères : un réseau collant qui épaissit le sang et retient la plaque.
Dans un gros tuyau, vous ne le remarquez pas. Dans un tuyau d'un millimètre, si. C'est pour ça que l'érection du matin disparaît en premier, puis que ça retombe pendant le rapport, puis que même le comprimé ne fait plus effet qu'à moitié. Le comprimé pousse le sang pendant quelques heures, mais il ne rouvre pas le passage.
Ce que fait Silencia
La nattokinase est l'enzyme du natto japonais qui dissout la fibrine. Le sang redevient fluide et la plaque perd le réseau qui la maintient. Quand le passage se rouvre, le sang arrive de nouveau jusqu'au bout, et il y reste.
Silencia vous apporte 10 000 FU de nattokinase dans une seule gélule, avec de l'ail vieilli, de la coenzyme Q10, du curcuma, de la bromélaïne, de l'écorce de pin et des pépins de raisin.
La preuve : une étude menée à Milan sur 300 patients cardiaques a montré que dans 67 % des cas, le problème d'érection était apparu en moyenne 38,8 mois avant le problème cardiaque. L'érection est le premier signal que les artères se bouchent.
La plaque a besoin d'un réseau. La nattokinase le démonte.
Pourquoi ça arrive
La plaque dans les artères, ce n'est pas que du cholestérol. Le cholestérol se coince dans un réseau de fibrine et y durcit. Plus il y a de réseau, plus le sang s'épaissit et plus le passage se rétrécit.
C'est pour ça qu'arrivent les chevilles gonflées le soir, la marque des chaussettes, les mains et les pieds froids et la tension qui ne baisse pas malgré le comprimé.
Ce que fait Silencia
La nattokinase découpe les filaments de fibrine. La plaque perd son appui et le sang circule à nouveau. L'ail vieilli soutient les parois des artères, la coenzyme Q10 donne de l'énergie au cœur, le curcuma et la bromélaïne calment l'inflammation.
La preuve : dans une étude sur 1 062 personnes, la nattokinase à 10 800 FU par jour pendant 12 mois a réduit la plaque de la carotide de 36 % et le mauvais cholestérol de 18 %. Dans une autre étude, elle a réduit la plaque de 36,6 %, contre 11,5 % pour la statine.
Pourquoi la nattokinase que vous avez essayée n'a pas marché
Pourquoi ça arrive
Dans les pharmacies françaises, la nattokinase se vend à 2 000 FU par gélule. Les FU sont les unités qui mesurent la quantité de fibrine que l'enzyme arrive à dissoudre.
Dans les études, le résultat n'est arrivé qu'avec les fortes doses. À 3 600 FU par jour, il ne s'est rien passé. Pour arriver à 10 000 avec celle de la pharmacie, il faudrait prendre cinq gélules par jour, tous les jours. Personne ne le fait.
Ce que fait Silencia
Ici, vous avez 10 000 FU dans une seule gélule, la dose des études, plus six actifs pour les artères et le cœur. Une gélule par jour au cours d'un repas, et c'est tout.
C'est la seule nattokinase en France avec 10 000 FU dans une gélule.
La preuve : le nombre de FU est écrit sur la boîte de votre nattokinase. Si c'est 2 000, vous en prenez un cinquième.

If you have any questions about your order, our team will get back to you within 24 hours.
One capsule per day with a meal, with a glass of water. At breakfast or lunch, whichever you prefer.
One capsule already contains the full dose: 10,000 FU of nattokinase and the six active ingredients for your arteries and heart. No tablets to count.
The exact time doesn’t matter. What matters is taking it every day, because fibrin dissolves day after day.
Arteries don't clear overnight. But blood becomes more fluid 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 returning.
Weeks 5-8: more vigor and greater stamina in bed, less ankle swelling, more stable blood pressure.
After 3 months: in studies, arterial plaque decreased by more than a third over one year.
We sell directly from the manufacturer to your door, with no wholesalers, no sales representatives, and no pharmacies adding their markup at every step.
At the pharmacy, 2,000 FU of nattokinase costs between €12 and €21. To reach 10,000 FU per day, you would need to buy five times as much: over €60 per month. With us, you get the full dose in a single capsule for less.

Nattokinase derived from fermented natto, 10,000 FU per capsule. Natto is fermented soybeans that the Japanese have eaten for breakfast for centuries.
It is combined with aged garlic extract, coenzyme Q10, turmeric, bromelain, pine bark extract, and grape seed extract. Vegetarian capsule, non-GMO, gluten-free.
It is manufactured in a GMP-certified facility. Each batch is tested by independent laboratories for purity, potency, and contaminants. Certificates of analysis are available upon request.
High blood pressure and cholesterol: yes, it is specifically designed for people whose arteries are under pressure. It can be taken alongside the medications you already take.

People with stents or taking blood thinners: it may be possible, but talk to your doctor first.
People with gluten intolerance: yes, it is gluten-free. Pregnancy and breastfeeding: it is not recommended.
Yes. Fibrin dissolves day by day, and in studies, results on plaque appeared within 6 to 12 months. You may notice the first changes sooner, but arteries need time.

Research-backed benefits
What this nattokinase really does
Nattokinase dissolves fibrin, the sticky mesh that thickens the blood and holds plaque in place. 10,000 FU in one capsule, the dose used in studies, with six active ingredients for the arteries and heart.
Clearer arteries
Less plaque, thinner blood
In studies, 10,800 FU per day for 12 months reduced carotid plaque by 36% and bad cholesterol by 18%. At 3,600 FU, nothing happened - that's why there are 10,000 here.
All your shape in bed
Firm erections, all the way through
The artery that carries blood to the penis is the narrowest in the body and the first to become blocked. When fibrin dissolves, blood reaches the tip again. Morning erections return, and it no longer goes soft halfway through.
Tension and legs
Less swollen ankles, warm hands and feet
Fluid blood flows better through small blood vessels. In the evening, your ankles swell less, sock marks disappear, and your hands and feet feel warmer. Nattokinase and aged garlic also help with blood pressure.
With your medications
You have nothing to stop
It is taken with the blood pressure pill, the statin, and diabetes medications. The pill lowers the number; nattokinase works on the arteries beneath it.

Regular, and worth it
For the first two weeks, I felt nothing. Starting in the third week, I had morning erections again, and by the sixth week, things in bed were like they were 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 had been taking the one from the pharmacy with 2,000 FU for a year, trusting it. No one had told me that studies use 10,000. With this one, after a month, my legs felt lighter and my feet warm, and my cholesterol went down.
My husband came back
For two years, my husband avoided me, and I thought it was my fault. It was the stress, it was his arteries. I make it for him every morning. After a month, he was the one who came to me. Thank you, truly.

5 reasons why

Stories from people who take it every day
“It’s just age, that’s all.” Then the cardiologist asked me a question.
I'm 63 and have had high blood pressure for ten years. I take amlodipine and a statin. For the past two years, things hadn't been working in bed. I'd get going, then lose my erection. Cialis helped at first, but less and less over time, and I doubled the dose without telling anyone. My wife thought I didn't desire her anymore. I pretended to be asleep when she came to bed. At my checkup, the cardiologist asked me, “Do you still wake up with an erection in the morning?” I turned bright red. He explained that the artery in the penis is the narrowest in the body and that it gets blocked first, years before the heart. The pill pushes blood through, but it doesn't clear any blockages. He told me about nattokinase. At the pharmacy, I found it in a 2,000 FU strength, and he said the studies use 10,000. I found this one. One capsule with lunch. By the third week, I woke up at six in the morning like I was forty again. After a month, I was the one who made the first move. At my next checkup, the cardiologist looked at the test results and told me, “Keep it up.”

Frequently asked questions
What everyone asks us
What distinguishes this nattokinase from the one at the pharmacy?
The dosage. At the pharmacy, nattokinase is dosed at 2,000 FU per capsule. In studies, nothing happened at 3,600 FU per day, whereas at 10,800 FU, plaque decreased by 36% in one year. Here, you get 10,000 FU in a single capsule, along with aged garlic, coenzyme Q10, turmeric, bromelain, pine bark, and grape seed.
The erectile dysfunction pill no longer works. Can this help me?
The pill pushes the blood along for a few hours, but if the arteries are blocked, only half the blood gets through. Nattokinase works on the passageway: it dissolves fibrin, which thickens the blood and narrows the arteries. Many of our customers come to us for exactly that reason, after years of taking pills that became less and less effective.
Can I take it with the medications I’m already taking?
Yes, it can be taken with your blood pressure tablet, statin, and diabetes medications without stopping anything. If you take blood thinners or Kardégic, talk to your doctor first, because nattokinase also thins the blood.
How long does it take to see the first results?
Lighter legs and warmer hands as early as the first 1 to 2 weeks. Morning erections generally return between the third and fourth week. Work on the plaque continues month after month: in studies, results appeared in 6 to 12 months. That's why we recommend at least 90 days.
Is it useful even if I don't have any problems in bed?
Yes. Nattokinase acts on the arteries throughout the body. It is also taken by people with high cholesterol or blood pressure, swollen ankles, cold hands and feet, or a family member who has had a heart attack.
How should I take it?
One capsule a day with a meal and a glass of water. At breakfast or lunch, whichever you prefer. A single capsule already contains the full dose.
One capsule a day. 10,000 FU, the dose used in studies.
Japanese natto nattokinase, at a dose you won’t find at a pharmacy, with six active ingredients for your arteries and heart. For clearer arteries and your overall well-being, every day.
