Three silicones, three profiles: which is which and what each one is for
If you’ve tried silicon supplements and didn’t notice anything, it probably wasn’t bioavailable organic silicon. There are three very common silicones on the market, and they vary a lot. This is the real difference.
Technical comparison of the 3 silicones: in one table
Before spending money on a supplement, look at this table. Origin, real bioavailability, published clinical evidence — everything that matters, side by side.

How much silicon really reaches your body?
When you read "contains X mg of silicon" on a label, what matters is not that number — it’s how much actually reaches your tissues. That’s bioavailability. Here are the 3 criteria that separate a silicon that works from one that only takes up space in the stomach.
What to look for in a silicon
Three objective criteria · without getting into percentage comparisons
"Organic" does not mean it comes from a plant. In chemistry, "organic" means it has a bond with carbon. For it to be truly bioavailable organic silicon, it has to be bonded to an organic carbon and absorbed without digestive transformation. Without that bond, it is not organic silicon — no matter what the label says.
I already chose G7 organic silicon. Liquid or capsules?
You’ve already chosen Silicium G7®. Now the practical question: liquid or capsules? The active ingredient is the same. What changes is when and how your body absorbs it. Each format fits a different routine.
Same active ingredient · same original formula · only the delivery matrix changes
Four elements that no other silicon on the market brings together.
There are many silicones on the market. But only one brings these four elements together at the same time. This is what sets Silicium G7® apart.
If you want truly bioavailable organic silicon, many labels say so. Silicium G7® is the original — the formula from the scientist who discovered that silicon could be absorbed by the human body. Everything else came later.

What people ask us most.
Six common questions when comparing types and formats of silicon.
01What is the best type of silicon?+
The one your body absorbs and uses. That is bioavailable organic silicon — and Silicium G7® is one by design: demonstrated bioavailability in humans, EFSA Novel Food 2017/2470 authorization, and 23 years with real people. Watch out for labels that say "organic silicon" but aren’t.
02What is the difference between organic and colloidal silicon?+
Bioavailable organic silicon (Silicium G7®) is absorbed by your body directly. Colloidal silicon is mineral particles in suspension — only the soluble fraction released slowly is absorbed. For building collagen and extracellular matrix, the difference is huge.
03What about plant-based "silicones" (bamboo, other plants)?+
They provide plant silica — it’s not the same. They are good botanical supplements with their uses . But if you want to rebuild collagen, elastin, or keratin, you need bioavailable organic silicon. The "organic silicon" label in these cases can be misleading.
04What is silicon bioavailability?+
It is how much of the silicon you take actually reaches your tissues. What matters on a label is not "contains X mg of silicon," but "how much of that you absorb." And between different chemical forms, the difference can be as much as 7×.
05Is liquid better or are capsules better?+
The active ingredient is the same. Liquid: fast absorption (peak 30-60 min), recommended when starting. Capsules: come with added synergies (vitamins, minerals), more convenient for maintenance. The effective choice is to match it to your routine and timing.
06Why does Silicium G7® stand out from other organic silicones?+
Four exclusive elements: original formula by Dr. Loïc Le Ribault (1995), GMP pharmaceutical production with purity ≥ 99.5%, EFSA Novel Food 2017/2470 and 23 years of pharmacovigilance with 70+ published studies.
