K2 MK-7 at 200 mcg
The pharmacy's calcium with K2 has 45. The Dutch study involving 244 women used 180 per day. This one has 200, in the all-trans form that the body actually uses.









Perché succede
Il medico ti ha detto calcio e vitamina D, e tu li prendi ogni mattina da anni. Il calcio arriva nel sangue. Ma per entrare nell'osso ha bisogno di qualcuno che lo porti lì: una proteina che si accende solo con la vitamina K2.
Senza K2 quella proteina resta spenta. Il calcio resta nel sangue e si ferma dove capita. Pensa ai mattoni scaricati davanti al cantiere senza il muratore: restano in strada. Nel corpo, la strada sono le arterie.
Per questo hai fatto tutto giusto e la MOC peggiora lo stesso. Non è colpa tua. Ti hanno dato il mattone senza il muratore.
Cosa fa Silencia
Silencia Ossa K2 è il muratore. La K2 MK-7 accende la proteina che fissa il calcio nell'osso e quella che lo tiene fuori dalle arterie. La vitamina D3 fa entrare il calcio dall'intestino. Il boro aiuta il corpo a non perderlo con le urine.
Non devi smettere il calcio che prendi. Da oggi va dove deve andare.
Perché succede
Più del 95% delle fratture del femore nasce da una caduta. Una donna italiana di 50 anni ha quasi una possibilità su cinque di rompersi il femore nella vita. Dopo, una persona anziana su cinque non cammina più da sola.
Le ossa contano. Ma contano anche le ginocchia e le gambe che ti tengono in piedi: se ogni scalino fa male, cammini meno, i muscoli si indeboliscono e cadere diventa più facile.
Cosa fa Silencia
Nella stessa perla c'è il collagene di tipo II, alla dose usata negli studi sulle ginocchia.
E con ogni ordine ricevi il Kit Ossa Sicure: il test della sedia per misurare a casa il tuo rischio di caduta e 12 minuti al giorno di esercizi studiati per gli anziani.
Perché succede
Forse la K2 l'hai già sentita, o è già nella tua compressa di calcio. Guarda la scatola. Nelle compresse di calcio con K2 della farmacia ce ne sono 45 mcg.
Nello studio sulle 244 donne ne usavano 180 al giorno, per 3 anni. Con la compressa della farmacia dovresti prenderne quattro al giorno, con 2.000 mg di calcio. Nessuno lo fa. È K2 annacquata: c'è, ma non abbastanza per fare il lavoro.
Cosa fa Silencia
Una perla ti dà 200 mcg di K2 MK-7 nella forma "all-trans", quella che il corpo usa davvero, sopra la dose dello studio. Insieme alla D3, al collagene di tipo II e al boro, in olio, perché la K2 e la D3 si sciolgono nel grasso.
È l'unica perla in Italia con questi quattro ingredienti insieme.

One softgel a day with lunch, with a glass of water. K2 and D3 are better absorbed with food.
The softgel already contains the full dose: K2, D3, collagen, and boron. No need to count tablets.
What matters is taking it every day, because calcium enters the bones day after day.
Knees change in weeks, bones in months.
Week 1-2: you settle into the routine, and calcium starts being directed where it needs to go.
Week 3-6: many women find their knees feel less stiff in the morning and evening aches are milder.
Month 2-3: your kit’s chair test score improves, and you feel more confident on the stairs.
From month six: that’s how long bones need. In studies, K2 was taken every day for 3 years.
We sell directly from the manufacturer to your home, without distributors, agents, or pharmacies adding a markup at every step.
At a pharmacy, to get 200 mcg of K2 along with the calcium in the tablet, you'd have to take four or five a day. Here, you get K2, D3, collagen, and boron in one softgel, for less than a euro a day.
There's no catch. Just a shorter supply chain.
You have 90 days to try it. If the sharp pains and bone pain don’t ease, 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.
Just email our customer support team. Your refund will arrive within 5-7 business days.

Recensioni Verificate.
Anna ha smesso di avere paura delle scale…
Prendevo il Dibase e il calcio da otto anni e ogni MOC era peggio della precedente. Nessuno mi aveva mai parlato della K2. Dopo un mese e mezzo le fitte alle ginocchia sono calate e adesso faccio le scale di casa senza tenermi al muro.
Lucia l'ha comprata per la mamma…
Mia madre ha 78 anni e l'anno scorso è caduta in bagno. Da allora aveva paura di uscire. Le preparo la perla con il pranzo e facciamo insieme il test della sedia ogni mese. A settembre si è alzata 11 volte, a giugno erano 8.
Giovanna ha rimandato l'alendronato…
Il reumatologo voleva darmi l'alendronato ma avevo paura per i denti. Ho chiesto se potevo intanto prendere la K2 con il calcio e mi ha detto di sì. Dopo un anno la MOC non era peggiorata, per la prima volta in sei anni.
Ingredients and mechanism
The 4 requirements that pharmacy-grade calcium does not meet, plus the laboratory test.
The pharmacy's calcium with K2 has 45. The Dutch study involving 244 women used 180 per day. This one has 200, in the all-trans form that the body actually uses.
Vitamin D3 helps calcium enter through the intestine, while K2 carries it to the bones. Together, in oil, because they dissolve in fat and pass through without oil.
40 mg per day, the same dose as in studies on knees with osteoarthritis. For the twinges you feel first, on the stairs and in the morning.
Boron helps the body avoid losing calcium through urine. Each batch is tested by independent laboratories at a GMP-certified facility.

I’ve had osteoporosis for twelve years and have seen four doctors. None of them ever told me about K2. Here, I understood in two minutes why calcium wasn’t enough. My knees are less stiff in the morning.
I got it for my mom after her wrist fracture. The exercise kit is well made, with illustrations, and she follows it. Now she feels safer at home.
For the first few weeks, I didn’t feel anything. From the fifth week on, the sharp back pains in the evening eased, and my chair test score went up. I’m continuing with the three-pack.

5 reasons why
What makes this pearl different from everything you've tried.
The bricklayer
Calcium and vitamin D alone carry calcium into the blood. K2 directs it into the bones. It’s the missing piece in the tablet you take.
200 mcg
The pharmacy’s calcium with K2 has 45 mcg. The study used 180. This one has 200, in the all-trans form that the body actually uses.
Off the beaten path
K2 keeps calcium out of the arteries. Those who consume more of it have half as much severe calcification in the aorta.
Four in one
For your bones and knees, and to keep calcium from being lost through urine. All in one softgel, without buying four bottles.
A pearl
One pearl with lunch, along with the medications you already take. Consistency is what makes the difference.

It's not your usual soccer
In first person
I'm 68 years old. I've been menopausal since I was 48. My first bone density scan, at 58, showed osteopenia: -1.8. My doctor prescribed calcium and vitamin D and told me to walk. I did that every day for ten years. At last year's scan, the number was -2.8. Osteoporosis. They suggested alendronate, but my sister had problems with her jaw while taking that pill, and her dentist wouldn't remove a tooth anymore. I asked for another consultation, with a rheumatologist. She asked me, “You've been taking calcium for years, right?” She took a piece of paper and drew bricks in front of a construction site. She told me calcium is the brick and vitamin K2 is the bricklayer, and without the bricklayer, calcium ends up wherever. I looked at the label on my calcium supplement: no K2. I found Silencia, a softgel with 200 mcg of K2, D3, collagen for the knees, and boron. I take it with lunch. After a month and a half, my knees were less stiff in the morning. In the third month, on the kit's chair test, I went from 9 to 12 stands. This year, my scan number hadn't gone down. For the first time in ten years.
