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 fine lines and 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.

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.

Suggested Use

Take one capsule, two times per day.

Great Hair and Nails!

Posted by iHerb Customer on Oct 09, 2017 | Verified Purchase

Great product for improving hair and nails, and that's only what can be visibly detected on the outside. Does more good things on the inside!

Thanks for your feedback!

I’ve seen improvement!!!

Posted by iHerb Customer on Oct 08, 2017 | Verified Purchase

I am from singapore and the weather here is hot and humid. I used to have full curly hair but i’ve rebonded my curls since 2007. Ever since, i’ve lost quite an amount of hair and since this year is my last year in my 20s, I decided to do something about it, fast. Before I lose all my good hair by the time i’m 40! And omg, i swear, i am seeing improvement! I still lose abit of hair whenever i’m washing or brushing through but not huge clumps anymore! I eat them on alternate days because it’s quite expensive and I don’t want them to run out fast. But it still works like magic. My nails are tougher and not easily chipped too! I am honestly truly impressed!!! Not much difference to my skin though because I have an autoimmune skin disease so I still need my medications, unfortunately. I wish I can rely fully on natural herbs. Thank you biosil!

Thanks for your feedback!

Import charges

Posted by iHerb Customer on Sep 26, 2017 | Verified Purchase

Beware if you're purchasing outside the US as there are charges. I didn't know this was a US based company (I purchased through I just found out a moment ago that I'd have to pay £18 to get my parcel. Far too expensive...

Thanks for your feedback!

My wife and I have used Biosil on a regular basis for the last three months or more. We have noted improvement in growth and strength of our hair. Also significant improvement in my toenail growth.
