Glucosamine & Chondroitin Help Maintain Knee Joint

Favorited Not Favorited
A 2-year study in people with osteoarthritis of the knee found that those who took a combination of glucosamine and chondroitin had only half the amount of narrowing of the knee joint space as those who took placebo. This beneficial finding differs from that of another large study published several years ago which did not find a benefit on joint space. The new study used a different form of glucosamine than the previous study.

Vitamin D and Knee Arthritis?

Favorited Not Favorited
Can taking vitamin D reduce the pain and progression of osteoarthritis of the knee? A new study found no benefit for people who already had sufficient levels of vitamin D. In fact, these people needed more anti-inflammatory medication during the study than those given placebo. However, as seen in many other studies of vitamin D, people who entered the study deficient in vitamin D appeared to benefit from being given vitamin D, experiencing reduced pain. For more details, see the update in the Vitamin D Supplements Review, which includes our tests of vitamin D supplements. If you suffer from osteoarthritis of the knee or other joints, also read about glucosamine and chondroitin, as supplements with these ingredients may help. We have tested many of these products.
