Collagen is the key structural protein for creating smooth skin, thick strong hair, and strong nails. During youth, you have a rich abundance of collagen. In addition, the collagen forms itself in a resilient “tight mesh” matrix. This “ideal” collagen condition prevents wrinkles from forming, gives skin elasticity, and helps create thick and strong hair. But starting at age 21, collagen diminishes by 1% per year. That’s when the vital collagen “mesh” begins to loosen. By age 30, the signs of reduced collagen on skin, hair and nails become visible.

BioSil™ Advanced Collagen Generator™ patented choline-stabilized orthosilicic acid (ch-OSA®) is clinically proven to make genuine collagen regeneration a reality. BioSil™ Advanced Collagen Generator™ “turns on” the body’s actual collagen-generating cells, known as fibroblasts. BioSil™ Advanced Collagen Generator™ has been tested in rigorous double-blind placebo controlled trials for both efficacy and safety.

Collagen: Generate It – Don’t Eat It

It’s important to note that BioSil™ Advanced Collagen Generator™ is not maPreferred Nutritionde out of collagen, it generates collagen. There’s a big difference. When you ingest collagen, the human body breaks it down and uses it as food. By contrast, BioSil™ Advanced Collagen Generator™ patented ch-OSA® complex helps your body to generate its own collagen for stronger, healthier and thicker hair; stronger nails as well as fewer fine lines and wrinkles.

This is my first time using collagen, but so far the results are promising. I will continue to buy this product.

They work!

My nails and hair have never looked better. I'm in my 60's, and both look better than when I was in my 50's.


Have been taking the product for several years noticed big improvement in my nails, hair and skin.

Biosil benefits.

I’ve been taking Biosil for a few years now. It is the very effective in helping in the production of collagen which makes my hair and nails grow at a healthy pace.


I have been using this for about 5 years & it has stopped me from having to take meds for Osteoporosis. My nails grow very fast & are very strong. I was hoping it would do more for my very thin hair, but I still lose hair every time I comb it. I am thinking of maybe changing to an actual collagen supplement instead of this one which is supposed to help your body produce Collagen.
