ch-OSA: The Scientific Breakthrough in Collagen!

Collagen is essential for beautiful skin, hair and nails as well as healthy bones and joints. But it 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 had the ability to create beautiful skin, hair and nails and promote health bones and joints. Best of all, it was proven safe. The historic discovery was hailed the "breakthrough in the science of collage." And it's now available to you in BioSil.

Thickens hair, good for nails

Posted by dav605 on Jun 30, 2012

My hair got very thick, even coarse, after taking this product for a few years. Since hair grows at about ¾" a month, it takes a while to see the difference in your hair. I had split nails that no longer split. Most surprising to me was that I had a pinky toenail that grew back after being gone for many years.

really wierd taste

Posted by Reviewer1308721 on Oct 01, 2010

This taste like fish, not pleasant, like taking bad medicine. I usually put it in a little water and hold my nose while I drink, then drink something to kill the after taste.
