Choline-stabilized orthosilicic acid formulas: A researched option for hair and skin when monomeric stability is maintained
Horsetail extract capsules: A plant-based option for those who prefer herbal sources, though absorption is limited
Colloidal silica liquids: An accessible entry point for daily mineral intake, with moderate bioavailability
Bamboo-derived silica powders: A high-concentration source from a plant-based origin, though assimilation varies
Your hair grows from collagen-rich tissue in the scalp, and the silica you choose directly affects how well that tissue functions. We evaluated dozens of silica formulations to identify which ones actually reach your follicles in a form your body can use.
Here is what we prioritized when selecting these options:
Silicium Laboratories developed LIVING SILICA® using a proprietary Heritage Concentrate™ process refined over 30 years of research by Sc. D. Loïc Le Ribault. This formulation delivers orthosilicic acid (the bioavailable molecular form your fibroblasts actually recognize) at a clinically demonstrated 64% absorption rate.
This is a dimension that often gets overlooked when comparing silica supplements for hair. Most formulations focus on concentration, but concentration means little if the molecules polymerize before reaching your intestinal wall. LIVING SILICA® uses anti-polymerization technology to keep monomeric silica stable throughout digestion, which means more of the active mineral reaches the cells whose entire job is to produce collagen in your scalp.
A double-blind, placebo-controlled study examining women with fine hair found statistically significant improvements in hair tensile strength, elasticity, and resistance to breakage after supplementation with stabilized orthosilicic acid (Wickett et al., 2007, Archives of Dermatological Research). LIVING SILICA® applies this same principle through a vegan, plant-based formula that contains no animal-derived collagen.
Customers following the 90-day protocol typically report early signs of improved hair texture and reduced shedding in the first two to three weeks, with more visible thickness and density developing over months two through four.
64% clinically verified absorption rate: Confirmed through a randomized, double-blind, crossover post-prandial study conducted by EURECAT Technological Center of Catalonia, which means nearly two-thirds of the silica you take actually reaches your tissues
Heritage Concentrate™ anti-polymerization process: Keeps silica molecules in their monomeric, bioavailable state so they can cross your intestinal membrane and signal fibroblast activity in hair follicle tissue
Vegan collagen activation: Activates your body's own collagen production rather than delivering animal-derived collagen peptides that get broken down completely during digestion
Flexible formats (liquid, capsule, powder): Available in liquid, capsule, and powder forms, all delivering the same active complex and identical results
Structured 90-day protocol: An intensive 60 mL daily dose for the first 30 days followed by a 30 mL maintenance dose, designed to rebuild depleted silica reserves and sustain collagen output
Clean formulation: Non-GMO, plant-based, free from artificial flavors, sweeteners, and colorants, with no thiaminase enzymes or crystalline silica contaminants
Pros:
The highest absorption rate among silica supplements (64%), confirmed through independent clinical testing
Activates fibroblasts at the gene level to upregulate your body's own Type I collagen production in the scalp
30 years of formulation refinement backed by university research and quality certifications
Cons:
The 90-day protocol requires consistent daily use before full results become visible, which asks for patience during the initial weeks
The liquid format has a slightly mineral taste that some prefer to mix into smoothies or juice rather than taking directly
Currently ships from the United States, which may add delivery time for international customers
Choline-stabilized orthosilicic acid (ch-OSA) uses choline as a stabilizing agent to prevent orthosilicic acid from polymerizing in solution. Clinical testing has demonstrated a 17% absorption rate for this form, making it the second-most bioavailable option after LIVING SILICA®. The Wickett et al. study (2007) that measured hair tensile strength improvements used this stabilization approach.
Ch-OSA formulas are typically available in liquid drop or capsule form, and the choline component offers additional nutritional value as an essential nutrient involved in methylation processes.
Ch-OSA features
17% absorption rate: Confirmed through clinical crossover studies, higher than plant-based or colloidal forms
Choline co-delivery: The stabilizing agent doubles as a nutrient involved in liver function and methylation
Drop format availability: Often dispensed in liquid drops added to water or juice
Ch-OSA pros and cons
Pros:
Clinically studied for hair outcomes including tensile strength and morphology improvements
The choline component offers additional nutritional support beyond silica delivery
Available in small-volume liquid drops that are easy to add to beverages
Cons:
Absorption rate of 17% means over 80% of the silica you ingest does not reach your tissues
Requires choline as the stabilizing agent, which limits the silica concentration per serving
Some formulations contain additional inactive ingredients for preservation that may not align with clean-label preferences
Horsetail (Equisetum arvense) contains approximately 5-7% silica alongside flavonoids and other plant compounds. It has a long history in traditional wellness practices for hair and nail support. However, the silica in horsetail extract tends to crystallize into phytoliths (fine grains of siliceous stone), which significantly reduces assimilation.
Clinical absorption testing has measured horsetail-derived silica at approximately 3%, according to research conducted at EURECAT Technological Center of Catalonia.
Plant-origin extraction: Derived from the Equisetum arvense plant, one of the oldest silica sources in herbal tradition
Additional plant compounds: Contains flavonoids, phenolic acids, and other antioxidant compounds alongside silica
Capsule and tincture formats: Widely available in capsule, tea, and liquid tincture forms
Pros:
A long history of traditional use for hair and nail support across multiple wellness cultures
Contains additional flavonoids and antioxidant compounds that may offer secondary benefits
Widely available in multiple retail channels and supplement stores
Cons:
Only 3% absorption rate means the vast majority of silica passes through your digestive system unused
Contains thiaminase, an enzyme that breaks down thiamine (vitamin B1) and can interfere with B-vitamin status over time
Silica tends to crystallize into phytoliths during processing, further reducing what your body can actually use
Colloidal silica consists of ultrafine particles suspended in a liquid or gel base. The small particle size allows for some absorption, and clinical testing has measured approximately 7% bioavailability for this form. Colloidal silica is often derived through manufacturing processes that convert silica particles into ions.
One consideration with colloidal formulas is that many contain highly oxidized silica, which limits how much your body can actually assimilate regardless of the stated concentration on the label.
Ultrafine particle suspension: Nanometer-range particles in a liquid or gel base for daily mineral intake
7% absorption rate: Higher than plant-based extracts but significantly lower than stabilized monomeric forms
Ionic conversion process: Some formulations convert colloidal particles into ionic silica for improved uptake
Pros:
The liquid or gel format makes it easy to add to daily routines without swallowing capsules
Nanometer particle size offers better absorption than crystallized plant sources
Some formulations include additional trace minerals beyond silica
Cons:
Many colloidal products contain highly oxidized silica that is minimally assimilated despite high stated concentrations
Higher concentrations (above 2mM or 120 mg/L) may lead to reduced solubility and potential kidney-related concerns
Does not address the polymerization problem that prevents larger silica chains from crossing intestinal membranes
Bamboo (Bambusa vulgaris) is the richest known plant source of silica, containing over 70% by dry weight. The extract is prepared from Tabashir bamboo leaves and stems and contains additional compounds including flavones, glycosides, and amino acids with antioxidant properties.
Despite this high concentration, the absorption rate for bamboo-derived silica remains approximately 3% in clinical testing, the same as horsetail. The silica in bamboo also tends to form crystalline phytoliths during extraction.
Over 70% silica content by weight: The highest natural concentration of any known plant source
Antioxidant co-compounds: Contains flavones, glycosides, phenolic acids, and amino acids alongside silica
Powder and capsule formats: Often available as a fine powder for smoothies or in vegetable capsule form
Pros:
The highest silica concentration of any plant source, which appeals to those who prefer botanical ingredients
Contains additional antioxidant compounds that offer secondary skin and hair benefits
Available as a powder that mixes easily into smoothies, juices, and functional beverages
Cons:
Only 3% absorption rate despite the high silica concentration, because the body cannot assimilate crystallized phytoliths
Contains thiaminase enzyme that may break down vitamin B1 with long-term use
High concentration does not translate to high bioavailability, as polymerization occurs before intestinal absorption

Your hair does not grow from the strand itself. It grows from the dermal papilla, a collagen-rich structure at the base of each follicle. Fibroblasts (the cells whose entire job is to produce collagen) maintain this structure by synthesizing Type I and Type III collagen fibers that anchor and nourish the growing strand.
When bioavailable silica reaches these fibroblasts, it upregulates collagen gene expression. This is not a vague nutritional effect. It is a targeted signal that tells your collagen-producing cells to increase output. Research published in peer-reviewed dermatology journals has confirmed that orthosilicic acid activates fibroblasts and increases collagen type I gene expression in human tissue (Barel et al., 2005, Archives of Dermatological Research).
The result is stronger follicle architecture, improved nutrient delivery to the hair root, and greater hair density and resilience over time. This mechanism also explains why silica supports keratin integrity. Collagen forms the scaffold around which keratin proteins organize, so when collagen production declines with age, keratin structure weakens alongside it.
A common assumption is that more silica in a formula means better results for your hair. The biology tells a different story. Silica molecules are inherently unstable. In solution, they tend to polymerize, meaning individual monomers link together into long chains that are too large to cross your intestinal membrane.
Concentrations above 2mM (approximately 120 mg/L) often trigger this polymerization cascade, which is why a formula containing 500 mg of silica per serving may deliver less usable mineral than a formula containing 30 mg in a stabilized, monomeric state.
This is where the distinction between types of silica becomes critical for hair outcomes. What reaches your fibroblasts matters far more than what goes into the bottle. Positively charged (cationic) silica particles have a heightened affinity for negatively charged cell surfaces, which enhances cellular uptake and improves the percentage that reaches your hair follicle tissue.
Silicium Laboratories built LIVING SILICA® around a single biological insight: your body already knows how to grow strong, dense hair. It has been doing it your entire life. The real question, especially as collagen production declines with age, is whether your fibroblasts have the raw materials and the activation signal to keep doing it well.
LIVING SILICA® delivers orthosilicic acid in a monomeric form at a 64% absorption rate, which means more of the active mineral reaches the collagen-producing cells in your scalp than any other silica form tested. The Heritage Concentrate™ process prevents polymerization, ensuring that the silica stays in its monomeric, bioavailable state from the moment you take it through absorption. This is not a general nutritional effect. It is a targeted mechanism refined over three decades of research and backed by independent clinical verification.
Silicium Laboratories gives you a 100% vegan, plant-based approach to collagen activation that works with your own biology rather than sending animal-derived peptides your body will break down completely during digestion. Explore the LIVING SILICA® collection to find the format that fits your daily routine.
Yes. Bioavailable silica activates fibroblasts in the dermal papilla (the collagen-rich tissue at the base of each hair follicle), stimulating increased Type I collagen production. LIVING SILICA® delivers this activation signal at a 64% absorption rate, strengthening the follicle architecture from which each strand grows. Clinical research has confirmed measurable improvements in hair tensile strength after supplementation with stabilized orthosilicic acid.
Biotin (vitamin B7) acts as a cofactor in keratin production, meaning it assists existing protein synthesis. Silica works upstream by activating collagen production in the scalp tissue that anchors and nourishes hair follicles. LIVING SILICA® targets this foundational collagen layer, addressing the structural environment your hair needs before keratin formation even begins.
Customers following the LIVING SILICA® 90-day protocol typically notice reduced shedding and improved hair texture in the first two to three weeks. More visible changes in thickness and density develop between months two and four. Consistency is the determining factor, as collagen rebuilding in the scalp follows a progressive timeline.
Both LIVING SILICA® liquid and capsule formats deliver the same active complex and produce identical results. The liquid uses reverse osmosis water as a base, while capsules contain the formula stabilized in acacia gum powder. Your choice depends entirely on format preference rather than any difference in efficacy or absorption.
Yes. Silica and biotin address different steps in the hair growth process. LIVING SILICA® activates collagen production in the follicle environment (the structural foundation), while biotin supports keratin protein assembly (the strand itself). Taking both targets complementary mechanisms, though silica addresses the upstream structural layer that many hair supplements overlook entirely.
