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.

Nourish Your Body's 3 "Beauty Proteins" - Naturally!

The condition of your skin, hair, and nails depends on three proteins:

Collagen "plumps out" skin, removing wrinkles and preventing them from forming. In addition, collagen is essential for strong, healthy bones and joints.

Keratin is the protein that's packed into your hair shaft. It gives your hair thickness, body, strength, and elasticity. Plus, keratin gives your nails strength.

Elastin gives your skin its ability to stretch and "bounce back" preventing fine lines and wrinkles.

With age, collagen keratin and elastin decline.

BioSil Hair Skin Nails, with clinically proven ch-OSA, is specially formulated to help nourish your body's 3 beauty proteins and restore them to more youthful levels.

Suggested Use

Take one capsule, two times per day.

Waste of Money!

Posted by Reviewer2067114 on Mar 17, 2010

I used this product for many months without any beneficial effects on my hair or nails. Switched to Flora brand Vegetal Silica (which contains much more silica than BioSil) and there was a big improvement in my hair and nails. Also, Vegetal Silica is way less expensive than BioSil. Don't waste your time on BioSil.

I was provided a similar product (RegeneMax) by a doctor to support collagen generation due to my injury (a fractured bone). I ran out of it and searched for the same ingredients (Biosil is identical according to the label). I was amazed that while the purpose of the formula was for support of my bones and joint tissue, my skin reflected less lines and more youthfulness after just one month (I am 56), an unexpected bonus! I higly recommend it for all the benefits it provides.

Miracle product

Posted by Reviewer1172951 on Nov 13, 2008

I started taking these several months ago hopeful but not really anticipating a major difference. Boy was I wrong. I have noticed not only a much cleare complexion, but my gums and nails are much healthier. My hair which was thinning is now fuller. I am quite pleased.

helps my hands

Posted by Reviewer1705781 on Oct 14, 2009

I tried this last year but felt nothing, so I stopped for several months. But this year it's different! My hands were dry and itchy from household chores. I decided to try this product again after reading The Science of Beauty (free from iherb, Thanks!). By today, still taking my 1st bottle, I can see and feel that my hands are not as dry and it's no longer itchy. I can also see a general improvement on my face, it appears smoother, which is a bonus!This product also helps my joints and I have less "cracking bone" sound. lol I'll definitely continue taking this.

Natrol, BioSil Veggie Caps

Posted by Reviewer1006053 on Sep 20, 2008

I read about this product in a nursing journal. Since I have always had very weak nails and my hair was thinning with age, I decided to try it. Into my first bottle I realized that it was making a real difference. For the first time since I can remember, my nails are not flimsy, but are growing long and strong. My hairdresser noted that my hair is thicker. I'm really amazed at the results.
