The Breakthrough in Collagen!

Collagen is essential for beautiful skin, hair and nails as well as healthy bones and joints. But starting at age 21, collagen diminishes 1% per year. By age 30, the signs become visible. For years, scientists searched for a method to give the human body the ability to regenerate its own collagen. But it took BioSil's landmark discovery of ch-OSA to make it a reality. Its capacity to generate collagen with your own DNA fingerprint makes ch-OSA the genuine breakthrough in collagen.

Doesn't turn back time or reduce wrinkles. There are better products

Posted by FightingFatigue on Aug 27, 2016

I used it religiously for over a year and the ageing process marched on. There has been no improvement in fine lines or wrinkles and my face looks older than when I started. I switched to collagen + C and saw an improvement after a month or so. For hair growth I found 5000 mg of biotin to be more effective than biosil. I also tried it on my dog and it was no help for osteoarthritis

I ordered this product due to my problems with nails and hair. My nails were very weak and this helped me, but for hairs no change. I have problem with hair loss.

Wanted to try it for bones, skin, aging, nails and hair. Hubby noticed a difference so I kept taking it... Onto second bottle. I use it with retin - a gel, rosehip, and coconut oils regiment. I have noticed my face looks less tired when I used it. It's tighter. My sister says I look 5-10 yrs younger after that regiment...
