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.

Thanks for your feedback!

really wierd taste

Posted by iHerb Customer on Oct 01, 2010 | Verified Purchase

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.

Thanks for your feedback!
