Vitamin D and Knee Arthritis?

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.

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.
