I'm 31 and I bought this product for hair loss, I read somewhere that collagen protein helps with hair growth and it has definitely helped with that but it has also got rid of my shoulder pain and calf pain which I had due to gym injuries. My husband also started using it due to his knee injury and he has also felt a big difference since taking this collagen protein. I am ordering my 4th tub and I'll continue ordering for a long time.
A fantastic product.
