The term “silica” is often used generically. However, in reality, not all silicon forms are the same.
Each form has a distinct chemical structure, stability, and biological behavior. These differences directly impact how silicon is absorbed and utilized in the body.
In short: the form of silicon matters.
For scientists, formulators, and brands, choosing the right form is critical. It determines:
Silicon is an essential trace element involved in:
However, its effectiveness depends entirely on its molecular form.
Some forms are highly bioavailable and active, while others are poorly absorbed or biologically inactive.
Below is a breakdown of the most commonly used silicon forms and their key characteristics.
Origin
Synthetic complex of orthosilicic acid combined with choline.
Bioavailability
Moderate to good (~17%), supported by human studies.
Stability
Improved compared to pure OSA, but still sensitive, especially in liquid formulations.
Applications
Origin
Naturally present in water and certain plant-based foods.
Bioavailability
Moderate to good, but short-lived.
Stability
Highly unstable. It rapidly polymerizes, reducing its absorption.
Applications
Origin
Extracted from silica-rich plants.
Bioavailability
Low (<5–10%), as silicon is bound to plant fibers.
Stability
Structurally stable within the plant matrix, but not readily bioavailable.
Applications
Origin
Natural (plants) or synthetic.
Bioavailability
Very low. Most of it is not absorbed.
Stability
Variable; prone to aggregation.
Applications
Origin
Quartz, sand, diatomaceous earth.
Bioavailability
Non-bioavailable (insoluble).
Stability
Highly stable, but biologically inactive.
Applications
Among all available forms, Monomethylsilanetriol (MMST) represents a major advancement in silicon science.
Origin
An organic, methylated silicon molecule developed by Dr. Loïc Le Ribault through advanced research in silicon chemistry.
Bioavailability
Very high (>60%), significantly higher than other forms. (See post: LIVING SILICA’s Innovation: Unlocking Bioavailability for Better Results
Stability
Intrinsically stable due to the Si–C bond, which prevents polymerization.
Solubility
Fully water-soluble, ensuring efficient delivery in liquid systems.
MMST overcomes the key limitations seen in other silicon forms:
This allows silicon to remain in a form that the body can readily use for biological processes, including collagen synthesis.
MMST is considered the gold standard for:
It is the core technology behind Living Silica®, delivering unmatched consistency and efficacy.
The performance of a silicon-based product depends on three key pillars:
Choosing the wrong form can result in:
For over 30 years, Silicium Laboratories has advanced the science of silicon through Living Silica®, powered by MMST.
This technology provides:
Silicon is a powerful ingredient, but only when delivered in the right form.
While many forms exist, Monomethylsilanetriol (MMST) stands out as the most advanced solution available today.
It is not just silicon.
It is bioavailable, stable, and functional silicon.
