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.


  • Helps in the formation of collagen

Really does work!!

I started using this product because my hair was falling out and my nails were in bad shape after having fake nails applied. Nails quickly improved and are beautiful now; smooth no cracking or peeling and hang nails are gone. Hair quit falling out. A few months ago I ran out of Biosil and didn't take it for a couple of months. I could see the difference in both. Started again and both improving again. Tablets easier to take than the liquid.

Worth the expense

This product is superior and has been used by a few people in our family for years now. We keep using this exact product because it works.


I am a senior and my hair was falling out by the handfuls. It now seems to have more body. I recommend this to anyone who finds their hair falling out.

Biosil to the rescue

I have been using BioSil for a couple of years now. It has helped not only my hair but also my prolapsed bladder. My whole body has benefited.

There's nothing better!

All I can say is don't bother looking for another collagen supplement. This is hands down the best one on the market. I have been using this product for years and I will never stop. My skin has completely cleared up and it's so soft. My nails are so strong and my hair grows like a horse! Thanks BioSil!
