Collagen type I and type II supplements are commonly used for joint health and are generally safe to take together. They may help improve joint comfort and reduce stiffness, but they do not repair damaged cartilage or cure arthritis. Knee sounds (crepitus) without significant pain are often not harmful and may be due to ligament or cartilage wear. If knee pain persists or worsens, proper evaluation with examination and X-rays is advised.
