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

I’ve been taking Biosil for over a year now can definitely see the results in my hair and nails.

It Works

My finger nails depend on it. Frail and peeling before; strong and healthy afterward. Seriosly!

Love it!

I've been taking this consistently for 1.5 years and my nails are so strong! I used to keep them short because of breakage but now they grow twice as fast and rarely break. I also noticed that I had lots of new short hairs a few months in, and now they've grown to about 6 inches long so my hair is much thicker and healthier. Would highly recommend!


I love Biosil. I take it twice a day as per the instructions for several years now. People cannot tell my age. I'm told my skin is glowing. Someone thought I had makeup on and when I told them I have absolutely no makeup on whatsoever and never use foundation. No need. But I like the compliments

BEST of the BEST!

I have been using Biosil since 2016 and can’t say enough about the product! There is no other like it on the market and the results are incredible. As with any supplement, overall health and lifestyle contribute to ones personal results. My mother, who is 80 years young, has been using it since 2017 and loves the results! Vitasave for the best prices!!!
