The first joint support supplement I bought was a hyaluronic acid supplement. It definitely helped. My joint pain lessened and my knees were not as stiff as before.
When this supplement ran out, I switched to another one that contains hyaluronic acid in addition to other beneficial ingredients, including collagen, MSM and glucosamine. This has been working much better for me. My joint pain is practically gone and I'm active again.
I wish I had discovered hyaluronic acid and collagen before.
