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 specifically formulated to help nourish your body's 3 beauty proteins and restore them to more youthful levels.

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.

Helped make my ligaments stronger!

Posted by Reviewer1487592 on Aug 19, 2010

I was having 3 yrs of problems with my sacrioliac joint not holding in my back due to stretched ligaments from years of misalignment. After taking this product for a month, it was the first time in 3 yrs, my chiropractor said my adjustment actually held!!! I am feeling stronger.

the one and only

Posted by 101010011 on Jul 11, 2012

been taking biosil for years, back to when jarrow was stamping their name on the bottle. im pretty sure it is the same orthosilicic formula after all these years, because my nails and hair have stayed in consistently good condition. the capsule version is definitely not as cost effective as the liquid, and if you cannot get past the odd/funky taste of the liquid, even masked in something sweet like fruit juice, then it is this pill version you should take.

Reduces Wrinkles and Younger Looking Skin!!

Posted by Reviewer2240367 on Dec 29, 2009

I'm writing to let you know what my results are. After 3 weeks with this, I began to notice less hair loss in the shower, less wrinkles (the fine lines are 40% gone!!); my small bald area ir bearly noticeable!! and my nails feel stronger/thicker. I am 51 years old and feel this gives me a younger look. My skin looks younger. So, I'm going to say, this product does deliver positive results.

Been taking this for about 3 months now, and my hair is much thicker and more lustrous. My nails have stopped splitting and are shinier too.
