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.

not sure

Posted by 5389865409077199298 on Dec 05, 2016

I used the product almost a year mostly for hair density. I do not think it affected my hair, but definitely feel my joints better. I do not have another explanation for that. I am exercising a lot and always feel some pressure in the joints after that. But since I started the supplement, I feel my joints much flexible. My husband suffers from discs hernia and I recommended the product to him also. He also experiences some relief. I am not saying he is not in pain at all. He said also he doesn’t feel that pressure, like it used to be.

Doesn't turn back time or reduce wrinkles. There are better products

Posted by FightingFatigue on Dec 03, 2016

AGEING: I used it religiously for over a year and the ageing process marched on. There has been no improvement in fine lines or wrinkles and my face looks older than when I started. I switched to collagen + C and saw an improvement after a month or so. For hair growth I found 5000 mg of biotin to be more effective than biosil. ARTHRITIS: I also tried it on my dog and it was no help for osteoarthritis. TASTE: It has a very strong unpleasant fishy taste so it needs to be consumed in a smoothie or swallow it quickly and follow it immediately with food

Horrible taste

Buy this only if you don't mind swallowing a terribly fishy tasting liquid

Important product every female should use.

BioSil is really important product, as it does not only work with your skin,hair and nails, but also keeps you young longer. It rejuvenates your body by generating collagen, that starts to decrease after the age of 20. It also makes your bones stronger and makes the wrinkles disappear. "Don't eat the collagen, generate it!" Must love it ! The taste ain't great, so mix it with orange or plum juice !
