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.

How to avoid the bad bad taste from this product.

Posted by iHerb Customer on Feb 17, 2018 | Verified Purchase

I bought this bottle since it is very much cheaper than the capsules that does not taste that bad. But i really wanted to avoid getting the taste in my mouth so i did experiment before i bought the bottle. I tested if drops could be used in gelatin empty capsules instead of powder, and it could. So the hack is, buy a lot of empty gelatine capsules and drop the drops inside the capsule. Have a glass of water to swallow capsule with available so the flush could happen quick. You really want to avoid getting the awful, pucking taste in your mouth. This bottle containes the worst taste i ever have put in my mouth. Really. But now you have a hack that gives you two months supply of your beauty supplement when calculated 10 drops serving size. My hair seems to be growing out again, not sure if it is due to this product, since i do onion and banana and oil + egg home made mask treatment on my hair. My skin seems like the same.... i take this most for my joints and to prevent aging. Have not had so much knee pain, but that could be due to increased omega 3 intake.

Thanks for your feedback!

I purchased this product as a friend of mine was using it and it did wonders for her skin I've been using it for over three weeks now and I have noticed a dramatic change in my hair my natural hair is thick coarse dry really damaged on the ends and dull since I've been using this my hair feels so much softer it is very shiny and I am not losing as much when I brush it anymore I am maybe losing 1/3 compared to what I was before I don't see much in Improvement for fine lines and wrinkles but I'm going to give it more time for that but as of now I am really impressed on how it is for my hair I never thought I would find anything that would help me with my hair that everyone says looks like straw
