BioSil BioSil - BioSil Mini Liquid Vegetarian Capsule, 120 lcaps
New Look! Same great product! BioSil - A patented source of choline-stabilized orthosilicic acid (ch-OSA®) that is clinically proven to help with the formation of collagen for thicker and stronger hair, fewer fine lines and wrinkles, improved skin elasticity, and stronger nails. By activating key collagen-generating enzymes and protecting newly formed collagen, it provides the most beautiful results for healthy hair, skin, and nails.

Why people keep reordering it
Best suited to: noticing thinning hair or brittle nails over months, wants a silicon source with clinical backing, not generic silica, comfortable with a twice-daily capsule routine.
What the research supports
Each mini capsule holds 5 mg of silicon as ch-OSA and 100 mg of choline. The bottle of 120 lasts about two months at two a day.
Trials on this silicon form use about 10 mg of silicon a day.
- Hair thickness (evidence: moderate, from randomized controlled trial)
- This silicon form drives the same enzyme step that cross-links collagen and keratin in the hair shaft. Trials at a matching dose measured thicker strands and less breakage over months.
- Skin elasticity (evidence: moderate, from randomized controlled trial)
- The same cross-linking step firms the collagen network under skin. A placebo-controlled trial at this dose found measurably better elasticity and fewer fine lines after 20 weeks.
- Nail strength (evidence: limited, from open-label study)
- The same mechanism is thought to firm the keratin-collagen structure inside the nail bed. Reports of less brittleness come mostly from smaller, open-label studies rather than controlled trials.

Is it right for you
Worth it if
- noticing thinning hair or brittle nails over months
- ch-OSA at this 10 mg silicon dose is the specific form and amount studied for supporting collagen and keratin production tied to hair and nail strength.
- wants a silicon source with clinical backing, not generic silica
- most silica supplements use forms with poor bioavailability, while ch-OSA is stabilized with choline specifically to keep the silicon absorbable.
- comfortable with a twice-daily capsule routine
- the studied protocol is split dosing, one capsule morning and one later in the day, not a single large dose.
Look elsewhere if
- wants visible results in a week or two
- Nothing works on hair or nails that fast. The trials at this ch-OSA dose measured hair thickness at around 90 days, because that is how long the tissue takes to grow out.
- already taking a choline supplement or eating a choline-heavy diet
- 200 mg of added choline here is on top of anything else you're getting, so check your total intake if you're already supplementing choline separately.
- looking for a topical fix for existing wrinkles or damaged nails
- a topical retinoid or nail-strengthening polish acts locally and faster; this works by supporting new collagen formation over time, not repairing what's already there.
What to expect
Hair and nail studies using this same ch-OSA dose typically showed measurable improvements in hair thickness and nail brittleness after about 20 to 90 days of daily use, with skin elasticity changes reported around the 20-week mark. Nothing here is felt immediately; it's a slow structural effect on collagen, not a same-day change.
How it compares
- Compared with plain silica or horsetail extract supplements
- ch-OSA is choline-stabilized specifically to keep silicon in a bioavailable orthosilicic acid form, which is what the hair and skin studies actually used. The tradeoff: you pay more for this stabilized, patented form than for a generic silica capsule with an unclear absorption profile.
