I started taking collagen earlier this year. It has been 6 months and I can't believe how good I feel since I started taking it. In the first two weeks, I noticed my joints no longer ached. This was the main reason I decided to start taking collagen, joint health. I have osteoarthritis and was a loyal glucosamine chondroitin user for 15 years. But I felt it wasn't working as well for me anymore. This is why I started searching for an alternative and how I found collagen.
