Biosil Review 2026: Does the ch-OSA Collagen Generator Work?

Biosil is a supplement brand built around one patented ingredient, ch-OSA, which it markets as a collagen generator for skin, hair and nails rather than a collagen supplement. This Biosil review explains what ch-OSA is, what the clinical evidence and customer reports say, what the current range costs and who is likely to benefit.

This review is for general information only and is not medical advice. Talk to your doctor or pharmacist before starting any supplement, especially if you are pregnant, breastfeeding, taking medication or managing a health condition.

Our verdict in brief

Biosil's Collagen Generator suits patient buyers who want a vegan, non-animal way to support skin, hair and nails and are happy to wait several months for modest changes. Skip it if you want quick, dramatic results, or if you are wary of a brand whose headline claims rest largely on its own studies.

How we researched this review

Simple Life Reviews did not take Biosil ourselves. We read the four reviews that rank for this query, the brand's homepage and product pages, and the study summaries those reviews cite. Two of the four reviews are promotional, with first-person success stories or purchase prompts, so we weigh them lightly and lean on the more critical sources.

What is Biosil?

Biosil belongs to Bio Minerals NV, which says it has operated for more than 30 years and launched its first product, Biosil Vegan Drops, in 1995, per Consumer Health Digest. The same review notes that the range is mostly marketed to women, covering collagen support, hair growth, hormone balance and healthy aging.

The Biosil homepage now groups its products into four goals (daily glow, hair rescue, hormone health and body support) and says it has spent $30 million on research, run double-blind trials and served 5 million customers.

What is ch-OSA?

Ch-OSA stands for choline-stabilized orthosilicic acid, a stable, absorbable form of silicon. Instead of supplying collagen, it is meant to help your body make more of its own collagen, keratin and elastin and protect what it already has. Because it contains no animal collagen, the products are vegan-friendly, which FamilyWeal and the brand both highlight.

Biosil products and prices

These are the brand's current prices on its own product pages. The Collagen Generator prepaid routine is a bundle, and the product page data we have does not state how many capsules it contains or how many months it covers, so check the page before buying; for comparison, a standard container of the original capsules holds 60, per Consumer Health Digest.

Biosil is also sold through other retailers. HighYA's older roundup, last updated in 2020, listed a 60-capsule bottle at $28.79 and a one-ounce bottle of drops at $25.59 on iHerb, so retailer prices may differ from the brand's, per its review.

Biosil Collagen Generator

The Collagen Generator is the product most reviews cover. It comes as capsules or liquid drops, and the drops can be mixed into water or juice. Consumer Health Digest puts a serving of the drops at about 6 drops, with about 120 servings per bottle, and lists 60 capsules per container for the original capsules.

The company advises against more than 10 drops or 2 capsules a day unless a health professional says otherwise, and says it has no evidence that higher doses work better, per HighYA. FamilyWeal adds that the drops taste unpleasant unless mixed into a drink.

Does Biosil work? What the evidence says

The most cited evidence is a randomized, double-blind, placebo-controlled study summarized by HighYA, in which 50 women with sun-damaged facial skin took ch-OSA or a placebo for 20 weeks. It reported better skin surface and elasticity measures and less brittle hair and nails in the ch-OSA group.

Biosil's own results, as HighYA lists them, are more striking: 30.0% fewer fine lines and wrinkles and 89.0% more skin elasticity after 20 weeks, and hair 13.1% stronger and 12.8% thicker after 36 weeks, all versus placebo. These are the company's reported figures, from fairly small trials, so treat them as an upper bound rather than what most users will see.

The homepage also claims its Advanced Hair Growth Formula grows over 12,000 extra growing hairs, per the brand. We found no independent source confirming that number.

How long until you see results?

Expect months, not weeks. The key study ran for 20 weeks, and the hair results were measured at 36 weeks, per HighYA. FamilyWeal lists slow visible change as a con, and one Consumer Health Digest reader reported no difference after three months. If you try Biosil, give it at least three to five months before judging it.

Is Biosil safe? Side effects

Ch-OSA is a source of silicon, a mineral found in many foods, and the sources generally describe Biosil as well tolerated. Still, some users report problems:

• Headaches. HighYA quotes Amazon reviewers who said they got migraines or headaches that stopped when they quit.
• Skin irritation. Consumer Health Digest lists possible skin irritation from some formulas among its cons.
• No effect. Several reviewers say they noticed no improvement after months of use.

If you take medication, have a kidney condition or are pregnant, check with your doctor first. The same applies to the GLP1 Weightloss Recovery product, priced at $59.99 on its product page: our sources do not describe its ingredients or any evidence for it, so if you use a prescription weight-loss medicine, ask your prescriber before adding it.

What customers say

Reviews are mixed but lean positive. HighYA reported a 4.4 out of 5 star Amazon average from nearly 2,000 reviews when it last updated its page, with older users praising stronger nails and thicker hair, and critics citing headaches and no visible change.

Consumer Health Digest adds complaints about shipping problems and orders that never arrived, and one subscriber who saw no change in skin, nails or arthritis after three months and wanted to cancel. We found no independent forum or Reddit discussion in our sources.

Who should buy and who should skip

Consider Biosil if you:

• want a vegan alternative to animal-based collagen
• are patient enough to take it daily for several months
• mainly want support for nails and hair rather than dramatic skin changes

Skip it if you:

• want quick, visible results
• are on a tight budget, since the hair formulas cost more
• get headaches easily, as some users report them

Pros and cons

Pros

• Vegan, non-animal approach to collagen support
• Some placebo-controlled research behind the core ingredient
• Flexible formats, including capsules and drops
• Wide range covering skin, hair, hormones and bones

Cons

• Results are slow and may be modest or absent for some users
• Headline percentages come from the company's own, fairly small studies
• Some users report headaches, skin irritation or shipping problems
• Drops taste unpleasant unless mixed into a drink
• Return policy not stated in our sources

Alternatives

If you want direct collagen rather than a collagen booster, marine or bovine collagen peptides are the common alternative, though they are not vegan. Simple biotin or silicon supplements are cheaper but have less specific evidence for skin. Ask a pharmacist which option suits your goals and any medication you take.

Our ratings

Overall: 3.5/5, because HighYA summarizes placebo-controlled evidence and a positive Amazon average, while slow results, side-effect reports and claims based on the company's own studies hold it back.

Biosil Collagen Generator: 3.5/5, because Consumer Health Digest finds it a reasonable vegan option for skin and nails, though some users see no change after months.
