What's Inside & Why Does It Work?

Mesoporosil®

Mesoporosil® is a patented, highly bioavailable form your body can truly absorb — helping to maintain normal bone strength, energise collagen pathways, and support the deeper structural processes that ordinary supplements often miss.

Vitamin D3

Mesoporosil® provides the underlying building blocks, while Vitamin D3 helps ensure those minerals reach the areas that rely on them — supporting normal bone density and resilience with age.

Vitamin K2

Directs minerals straight into your bones for healthy mineralisation. Paired with Mesoporosil® and Vitamin D3, it helps your body absorb minerals — and actually put them to work in keeping bones strong.

Calcium

Most effective when paired with cofactors like Silicium, Vitamin D3 and Vitamin K2.

At 62, I worried about bone density, but after four months on Silastra my posture feels stronger and I’m walking the dog on uneven paths in the Peak District without fear of slipping.

The gradual improvement in joint resilience has been noticeable. I’m carrying heavier shopping bags up the stairs in my London flat without that old hesitation.

F
Fiona M.

Bone and joint support feels steadier, though it took a couple of months to build. Definitely noticing more structural confidence day to day.

O
Olivia P.

My knees feel more supported on long walks. Climbed the hills near Bath recently and felt solid the whole way – that quiet reliability is everything.

T
Thomas B.

As a 58-year-old keen golfer, the difference in hip stability is clear. Swings feel grounded and I’m not wary of twisting like before.

What Sets Us Apart?

Silastra addresses a key factor linked with joint challenges… age-related silicium loss.


This vital mineral plays a role in reinforcing bone structure, protecting cartilage and strengthening connective tissue as you move.


By topping up these silicium levels, Silastra supports daily mobility, easing tightness, stiffness and intense joint load at the root.

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.
