I thought pain, stiff joints and tired skin was just age. Silastra proved me wrong, I feel strong again.

Why Silicium?
Silicium is the foundational mineral your body uses to build and maintain cartilage, bone and connective tissue, the structures that let you move without pain.
But after 30, your body’s silicium levels plummet — and food or standard supplements can’t replace it.
Less than 0.1% of dietary silicium is actually absorbed, so most people lose the ability to rebuild what daily wear, inflammation or bone-on-bone damage has taken away.
That’s why even the best calcium, collagen or glucosamine formulas often fall short. Without enough bioavailable silicium, your body simply can’t repair or restore.
After 20+ years of research, scientists developed Mesoporosil® — a patented, Triple-A Certified form of silicium that’s 96.7% bioavailable & only available in Silastra.
It delivers the exact compound your body needs to rebuild cartilage, strengthen bone, and restore mobility from the inside out, offering real hope to anyone told there’s “nothing left but surgery.”
Is it safe?
Yes — Silastra is carefully designed for everyday use.
It’s made with a patented, Triple-A Certified silicium complex that has been evaluated for more than 20 years in scientific research.
Unlike aggressive ingredients or fast-acting blends, silicium is a naturally occurring mineral used by the body, and our formulation simply replenishes typical age-related decline.
Each batch is produced to high manufacturing and quality-control standards, with thorough testing to ensure purity and product integrity.
And with our 365-Day Money Back Promise, you’re fully protected while you try it.

Who is Silastra for?
Silastra is for anyone who wants to maintain strength, steadiness and day-to-day physical confidence as their body evolves.
It’s especially suited for:
Women in peri- and postmenopause, when shifts in collagen and bone-related processes become more noticeable
Adults over 40, who naturally produce less silicium as part of healthy ageing
Those who train, lift, walk, run or stay active, placing extra demand on joints and connective tissues
Silicium gradually drops in everyone — and it cannot be meaningfully restored through diet or typical supplementation alone.
What's inside Silastra?
Mesoporosil® – A patented, highly absorbable silicium proven to support bone integrity and collagen pathways
Calcium – Key mineral for everyday skeletal strength
Vitamin D3 – Enhances the body’s use of calcium
Vitamin K2 – Helps direct minerals to where they’re structurally needed
How is Silastra different from other collagen supplements?
Most collagen supplements give you collagen the body can’t use directly. Silastra doesn’t add collagen — it triggers the pathways behind it.
Once collagen is digested into amino acids, the body still needs silicium to reconstruct it into strong, resilient fibres.
Silastra delivers bioavailable silicium, which supports the body’s natural collagen production mechanisms.
That leads to stronger, better-organised collagen where it matters most — across joints, skin and connective tissues.
What is the serving amount?
Take one softgel per day with water.
For optimal support, take consistently for 8–12 weeks.
What if I forget a day?
Carry on as usual the next day. What matters most is steady, ongoing use.
At what age should I start taking Silastra?
Subtle structural changes begin earlier than most expect — usually late 30s to early 40s.
Starting Silastra around age 40, or sooner if you’re active or entering perimenopause, helps maintain long-term stability.
Early support means stronger structure later.
What exactly does Silastra do?
Silastra helps your body rebuild its foundation from the inside out by restoring a mineral it gradually loses over time: bioavailable silicium.
This core nutrient supports:
Strong, resilient bone architecture
The body’s natural collagen-building processes
Joint and connective-tissue integrity
By targeting the body’s underlying structure, Silastra helps you feel more stable, less delicate and more assured in how you move.
A smart choice for anyone experiencing menopause, age-related changes or an active routine.
How is Silastra different from other bone supplements?
Many bone formulas focus on excess calcium, a strategy that doesn’t fully tackle the body’s changing structural demands.
Silastra delivers highly absorbable silicium, the mineral involved in maintaining bone quality, collagen mechanics and joint support.
The result is a foundational approach — one that helps your body re-fortify its own structure, improving how supported and stable you feel day-to-day.
Can pregnancy or breastfeeding affect bone health?
The body uses a significant amount of the mother’s stored minerals during pregnancy and breastfeeding. Many women prioritise bone and connective-tissue support postnatally, and Silastra can be part of that routine.
Always speak to your doctor first before use.
How long will it take until I notice the results?
Structural changes take time. While improvements are not instant, many users report feeling more stable, aligned or flexible over several weeks to a few months.
Allow a minimum of 60 days for noticeable changes.
I’m an athlete. Will this help with joint or bone stress?
Absolutely. Many active and high-impact athletes use Silastra to support their structural base.
It helps reinforce collagen and connective-tissue integrity during repeated stress.
Helping You Stay Strong, Active & Naturally Unbreakable
I teach Year 2 and used to dread sitting cross-legged with my class because standing up was embarrassing. Six weeks on Silastra and I realised I’d gone the whole day without bracing on my desk to rise. It’s little, but it feels huge. I even carried book boxes down to the library without asking for help. That’s the win.
I feel ‘myself again’. I love it. Enough said.
Airport test: lifted my hand luggage into the overhead by myself. Last year I couldn’t.
I didn’t realise how much I was “holding my breath” walking down stairs. I’m not doing that now.
The backs of my hands look smoother. That was my “ageing tell”. It’s subtle but noticeable to me.
Gardening without the “sit down every 10 minutes” routine. I forgot what that felt like.
Stopped making little excuses to avoid walks. Now I just… go.
I feel steadier in the shower. Not something I ever thought I’d review, but here we are.
My “neck area” looks less like it’s folding. Sorry for the bluntness. I’m thrilled.
Got through a long car journey and didn’t hobble out like a cartoon character.
Not a “wired” energy — just less heavy. Like my body’s not negotiating with me all day.
Neck turns in yoga without bargaining with my body first. Feels like trust.
Wore heels to church and didn’t clutch the pew. Small miracle.
Took about 5 weeks to notice. Arms look less crepey now. Not dramatic, but I’ll keep going.
Added a second loop to the dog walk. Later realised I went upstairs without the handrail. That felt… young.
Back to doubles after sitting out two seasons. Elbow isn’t barking after serves anymore.
I caught myself walking faster through the supermarket. No wobble, no hesitation.
Make-up sits better on my cheeks now. Less texture. I’m not mad about it.
