We are often asked if collagen can promote overall joint health and joint recovery from injury or wear and tear. Certainly, many of our customers take our collagen peptides for arthritis and joint pain. However, these positive testimonials are also supported by studies proving that collagen can play this role in managing joint pain. For example, a 2014 study of 94 women from the ages of 40-70, all experiencing knee joint problems associated with osteoarthritis, took collagen or a placebo daily for six months. The collagen-taking sample experienced a 24% reduction in discomfort by the end of the trial, suggesting that collagen reduces joint pain. Moreover, the same study demonstrated a 7% improvement in knee joint function for the collagen-taking sample. We recommend any of our Edible Health collagen powder for knee pain - try for yourself!
