NEW YORK (Reuters Health) - Taking daily vitamin D doesn't keep knee pain from getting worse or slow the loss of cartilage for people with osteoarthritis, according to a new study.

Previous research suggested that among people with the joint disorder, those with higher levels of vitamin D in their blood tended to have a slower progression of symptoms. But whether that meant taking more in supplement form would also have a protective effect was unclear.
