Mild Vitamin D Deficiency Linked to Increased Knee Pain

Vitamin D deficiency has been associated with a number of medical maladies—from depression to chronic pain. However, investigators have not pinpointed a threshold value (deficiency) associating vitamin D and chronic pain. Now researchers at the University of Florida, Gainesville, have shown that hydroxyvitamin D levels less than 25 ng/mL are associated with increased osteoarthritis symptoms—pain, stiffness, physical dysfunction—and increased pain sensitivity to palpatory pressure. According to the lead investigator, Toni Glover, MSN FNP-BC, these findings support a relationship between low levels of vitamin D and chronic knee pain. Also, "a vitamin D level less than 25 ng/mL may provide a clinical threshold used to treat vitamin D insufficiency with the goal of mitigating chronic pain," she concluded. Ms. Glover was a winner of the APS Young Investigator Travel Award.
