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.

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.

Since taking Biosil, I have noticed an improvement in both my hair and finger nails. I would recommend it.

I have found Bio-Sil to be effective for improvements in the strength of hair and finger nails. I no longer have a combful of hair after combing my hair. I believe that a trial of this product requires about a year's use to establish its effectiveness.
