Vitamin D and the knee

A tall glass of milk.

The Basics of Vitamin D

From the U.S. Department of Health and Human Services, I’m Ira Dreyfuss with HHS HealthBeat.

A better look at whether vitamin D supplements can help people deal with osteoarthritis finds the vitamin doesn’t seem to make a difference.

At Tufts Medical Center in Boston, Timothy McAlindon followed up on earlier research which indicated that vitamin D might affect conditions that could lead to osteoarthritis. In his experiment, some people with knee osteoarthritis got vitamin D and some got an inactive substitute. He followed them for two years to see whether the people using supplements had less knee pain and less loss of cushioning cartilage:

“We found no effect either on the amount of knee pain that people experienced or on the amount of cartilage that they lost.”

The study in the Journal of the American Medical Association was supported by the National Institutes of Health.
