I took Collagen Pro Active some three years ago. At that time I was having a hard time with pain in my knee and had used almost every product available in the market. For that reason I told myself that I had to try Collagen Pro Active. Slowly but gradually I experienced incredible improvement in my knees and generally in my joints. Moreover, as I used it for months I also experienced improvement in my hair, face and nails! That was the reason why I recommend the product to all my friends and acquaintances. We all need to become addicted to Collagen Pro Active!
I use it for about two months and I can say that I experience a lot of improvement. I had knee pain when running and now this is gone! It even helped me to overcome a muscle damage I had for about 3 years!
