    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.

    This product works

    Posted by iHerb Customer on Jan 17, 2018 | Verified Purchase

    I have been taking this dailly for several months. It does seem to make my hair grow thicker. At least it doesn't drop out as much. My skin is not too bad either. People say I don't look my age. I am 73.

    Thanks for your feedback!

    Less hair fall

    Posted by iHerb Customer on Jan 05, 2018 | Verified Purchase

    I have completed 120 capsules and after haven taken half a bottle, the very noticeable fact is that when I wash my hair, there is only half or a third of hair falling into the drain protector. So it's great! I have not noticed any significant changes to hair growth or skin yet. Bought another to monitor further.

    Thanks for your feedback!

    Better than the drops

    Posted by iHerb Customer on Dec 04, 2017 | Verified Purchase

    i don't know how well these work yet but I will say that there is no difference in the ingredients from the liquid to the pills. I ordered both but will stick with the pills. The liquid drops taste horrible.

    Thanks for your feedback!

    Good results

    Posted by iHerb Customer on Nov 29, 2017 | Verified Purchase

    I have been taking this for about two months, I bought it to stop my hair loss, for some reason I was loosing fist full of hairs daily. Fortunately it stopped, perhaps it was the placebo effect, but it happened after I started taking this product. I also noticed a difference in my fingernails and one of my knees was bothering me a little(for about 2-3 months) and about 1.5 months after starting to take this, it stopped. As for my skin, I cannot say I noticed a difference, but I was not expecting anything, my main problem was the hair loss. I recommend this and will buy again. Also, big points for being cruelty free.

    Thanks for your feedback!
