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.

Makes a Tremendous Difference

Since I have been taking BioSil daily since 2009 I feel qualified to tell you that the product strengthens my fingernails so I can grow them out without peeling, splitting or breaking. Prior to taking BioSil my nails were thin and weak. My hair has become stronger, there is more of it, and I have my natural color, all important attributes of BioSil. Biosil is something I take everyday, depend on, and am grateful for.

I was recommended to use this by my MD/Holistic person, she said it will help with bone building. Hard to know yet if it is making a difference.

No difference

I take this for a month and no difference or improvement in my hair and nail. My nail still break. Maybe it has to take for longer to see good result.

BioSil 1 bottle used- too early maybe.

Posted by Reviewer2843863 on Mar 26, 2014 | Verified Purchase

Frankly i do not see a difference in hair skin or nails. I have developed soft brittle nails with ridges and my hair texture feels like old lady hair and im not even 40. Now finished one bottle of 30 capsules. Maybe one bottle is not enough for my problem so i will give this a try for 2- 3 months at least. Hope to write a positive review then.
