FRIDAY, Aug. 23 (HealthDay News) -- Older women seeking a cure
for swollen, painful joints likely will find that taking calcium
and vitamin D supplements won't reduce the severity of their
condition, a new study reveals.
Researchers analyzed data from more than 1,900 postmenopausal
women in the United States who were randomly selected to receive
either calcium carbonate with vitamin D3 daily or an inactive
Both groups had similar levels of joint pain and swelling at the
start of the study period, and that was still the case two years
later, the investigators found.
"Joint symptoms are relatively common in postmenopausal women," said lead investigator Dr. Rowan Chlebowski and colleagues at the Los Angeles Biomedical Research Institute at Harbor-UCLA Medical Center. "However, daily supplementation with 1,000 milligrams of calcium carbonate and 400 international units of vitamin D3 in a randomized, placebo-controlled clinical trial setting did not reduce the self-reported frequency or severity of joint symptoms."
The findings do not contradict current recommendations for
vitamin D intakes for bone health and fracture-risk reduction, the
study authors said.
The study was scheduled for publication in the
Journal of the Academy of Nutrition and Dietetics.
Previous research looking at how low calcium and vitamin D
levels affect joint health has produced mixed results.
