Biosil isn't collagen, it's better!
Biosil’s active ingredient, ch-OSA®, has a unique 2-in-1 effect, activating your body’s own production of collagen, keratin, and elastin, while simultaneously protecting existing levels of collagen from degradation.
Backed by scientists
ch-OSA® was invented in the early 1990s by a medical microbiologist at the University of Antwerp. Thirty years and $30 million later, researchers have not just tested but clinically proven ch-OSA®'s health and beauty benefits while also optimizing its delivery to your collagen-generating cells. Having had all this time to study ch-OSA® gives us the benefits of knowing its full long-term effects and safety.
Choose from our original ch-OSA formula in Original Capsules, Liquid Capsules, or Liquid Drops. Additionally, explore Biosil Collagen Generator Plus with Vitamin C, Biosil Advanced Hair & Nails with Biotin, and Biosil Healthy Aging with Selenium.
