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.

Customers Reviews:
  • I use it for couple of years by now together with hylauronic acid pills and they work great together! Really adds one to another! Skin is smooth and all small wrinkles go away. Can not say much about nail improvement though, seems to me same like with or without it. The taste is funky, I prefer not to dissolve it in water or juice (the substance is heavy, so the drops go right on the bottom of the juice and you have to shake it and refill couple of times to get all of it from the glass but simply drop it on my tongue an drink some water right away.
  • far more effective in liquid form than in capsules. The only drawback is that it tastes foul, almost like rotten fish. I have to hold my breath when i swallow it and i can only endure the unpleasant taste and smell because i have noticed a visible improvement in my skin, hair and nails.
  • It is my favorite collagen generator. I’ve been taking 5 bottles. I have a hard time eating pills. This product is liquid supplement. It’s easy to eat, but taste is terrible. My recommendation is taking the drops with juice. My skin becomes fairer.
  • It is better than pills. Even the taste is terrible, you can see some result already in about 3 weeks
  • I have a chronic biliary liver disorder, so it may not be because of the product. Half of my fingernails are severely deformed and soft. There has been no change since taking. Have taken 1 oz so far.
