Product Information



Collagen is essential for beautiful skin, hair and nails as well as healthy bones and joints. But starting at age 18, 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. 

BioSil®, with clinically proven ch-OSA®, is specifically formulated to help nourish your body’s 3 beauty proteins (Collagen, Keratin & Elastin) and restore them to more youthful levels.


  • Reduces fine lines and wrinkles*
  • Thickens and Strengthens hair*
  • Strengthens nails*
  • Promotes healthy bones and joints*
  • Vegan Collagen

Saved my hair!
I found out about Biosil while I was researching thinning hair. I'm a 28 year old, healthy, normal weight female, yet my hair was definitely thinning. My scalp would shine through no matter how I wore my hair. I blame my high stress career.
Within the first 2-3 weeks of taking this vitiman according to the instructions, I noticed my nails looked gorgeous! I have always had brittle nails, in fact I remember my friend commenting on my "weird nails" in elementary school. Even my nail artist noticed. I was thrilled.
About a month or so in, I started noticing little baby hairs growing in the hairline around my forehead! I was so thrilled. Now about 2+ months in, I was just in the bathroom playing with my hair and I was TRYING to find my scalp under my hair and couldn't. I can definitely see where my problem areas have been filling in.
The other thing I noticed (which I'm unsure if it's the Biosil or the other vitimans I've been taking, mainly the GNC Women's Whole Body daily vitapacks) is that the chronic keratosis pilaris on the back of my legs looks way better as if it's cleared up some. I wasn't expecting this as a benifit but I'll certainly take it! Very pleased with this product so far.

I highly recommend it! I am a 41 yr old woman with moderate signs of age on my skin and needed a 911 hair vitamin rescue due to all my hair coloring and highlights for many years and being allergic to biotin I had to find a product without Biotin to rescue my hair ... So I found this Biosil and My hair and nails made a huge improvement after first bottle, skin looking good , No side effects or breakouts on my skin and I am buying my second bottle. Great product for the price ????????
