I recently started taking collagen. I think it has helped with joint pain. I thought it was helping my skin, especially finger and heel cracks, but my fingers are cracked now from washing them so much.
However, I can’t live without my Purity Products H.A. Joint formula. It’s hyaluranic acid. Ooh, it says it’s from collagen, and it has a lot of Vitamin C! They seem to have a cheaper version with fewer ingredients, too.
I also just started taking Vitamin D because I was a juror on a medical malpractice case, and they taught us a lot about bone density.
