Nourish Your Body's "Beauty Proteins"-Naturally!

The condition of your skin, hair, and nails depends on three proteins: collagen, keratin, and elastin. They are known as your "Beauty Proteins". Collagen "plumps" the skin, removing wrinkles and preventing them from forming. In addition, collagen helps to continuously hydrate your skin from the inside out. Keratin is the protein that's packed into your hair shaft. Keratin gives your hair thickness, body, strength, and elasticity. Plus, keratin gives your nails strength and clarity. Elastin gives your skin its ability to stretch and "bounce back" preventing fine lines and wrinkles. With age, all three decline. BioSil is specifically formulated to help nourish your body's beauty proteins to restore them to more youthful levels.

New research demonstrates that BioSil (ch-OSA) promotes healthy bones and joints. A recent study shows ch-OSA along with calcium and vitamin D improves bone mineral density at the hip region by 2% compared to calcium and vitamin D alone—or twice the clinically relevant threshold. In addition, ch-OSA demonstrated an overall clinically relevant improvement in collagen and other key bone formation markers.

ch-OSA: The Scientific Breakthrough in Collagen!

Collagen is essential for beautiful skin, hair and nails as well as healthy bones and joints. But its wasn't until the landmark creation of ch-OSA (choline-stabilized Ortho Silicic Acid) that a scientific breakthrough to generate collagen would become a reality. For years, scientists recognized that orthosilicic acid (OSA) had the potential to stimulate the production of collagen but there was a problem.

OSA is highly unstable and converts to a form not well absorbed by humans. Then after years of research and development, an elite team of international scientists created and applied their "choline-stabilization" technology to OSA. Their patented innovation, known as ch-OSA complex, became the first biologically stable and absorbable form of OSA. Suddenly, the world had a scientifically-validated orally-active collagen generator. Soon after, rigorous clinical trials proved that their specific new ch-OSA complex has the ability to create beautiful skin, hair and nails and promote healthy bones and joints. Best of all, it was proven safe. The historic discovery was hailed the "breakthrough in the science of collagen". And it's now available to you in BioSil.

Waste of Money!

Posted by iHerb Customer on Mar 17, 2010 | Verified Purchase

I used this product for many months without any beneficial effects on my hair or nails. Switched to Flora brand Vegetal Silica (which contains much more silica than BioSil) and there was a big improvement in my hair and nails. Also, Vegetal Silica is way less expensive than BioSil. Don't waste your time on BioSil.

Thanks for your feedback!

Seems to be working...

I have also been taking Biotin for my hair and nails, so I'm not sure if it's the combination of the two products or the Biosil. But, I have seen an improvement in my hair, nails and skin. Just ran out and I'm going to order some more today.

Thanks for your feedback!

Worth the Money

I have been taking it to combat hair loss and knee joint pain. After using it for one month, I suffer from less hair loss and fewer episodes of pain. That said, I also include MSM, biotin, fish oil, borage oil into my regime.
