The Breakthrough in Collagen!
Collagen is essential for beautiful skin, hair and nails as well as healthy bones and joints. But starting at age 18, 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:

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


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 and clarity.


gives your skin its ability to stretch and “bounce back” preventing fine lines and wrinkles

Definitely makes hair grow faster...
My hair stylist recommended this b/c I told her my hair grows so incredibly slow and breaks a lot. I can't get it to grow out b/c every time I get my hair colored and cut, we have to cut off the whopping full inch that grew over 10-12 weeks. Anyways, been taking it for about 5-6 weeks so far. 1 pill, twice a day. My hair has grown in 6 weeks what it normally does in about 10. I can't believe it. Supposedly it's supposed to make it thicker too, but it's too soon for me to tell. Buuuut I hope it does b/c my hair is super thin and breaks A LOT. Can't really tell anything w/ the skin and nails but I can def tell a difference in how fast my hair is growing.

Bad Knees
I read an advertizement about Bio Sil in your monthly magazine. I went online to see if I could get anymore information about the product. Turns out some people felt their joints gained increased range of motion after using Bio Sil for a few months. I turned out to be one of those lucky people too.

I would recommend this product to anyone suffering from ailing joints. After taking the product on a daily basis for the first month, you can use it every other day Who knows you may be one of the lucky ones too.

Before Bio Sil, I had tried other products. I got some relief but nothing like Bio Sil.

I take 2 a day. I've been using these for about over a month and I'm so amazed at the results already. My hair was thick to begin with but it always used to fall out when I washed it or ran my fingers through it and I feel like it used to break easily. But since I've taken these I see so much less hair loss it amazes me. My hair is also thicker already. It also worked wonders on my nails, I used to have very thin and easily breakable nails but now I have a hard time even biting them. I haven't really noticed much difference with my skin yet, but I am young so I don't have many noticeable wrinkles to notice much difference yet. I highly recommend these for anyone who needs help with hair or nail issues. Both of my parents take them too and they love it as well.

It works for me
I have been taking two tablets a day for about two years. I am 55 and get comments on how young I look quite frequently. I feel the product works for me. My hair, nails and skin have improved with the use of this product.

I have taken BioSil for three months , and did not notice a difference in my hair, skin or nails. My hair ,skin and nails looked better when i was taking GNC brand of hair, skin and nail formula . You also get twice as many pills for half the price of BioSil.

Great results!!!
I was recommended this product and was a little apprehensive for the price but OMG it took no time (less than a week) to see a marked improvement. I've read other things that you should do an on off schedule so, in the meantime I'll save because this is a keeper.
