(NEW YORK) — Two recent studies in the Annals of Internal Medicine look at the benefits of Vitamin D supplements.
While researchers found that Vitamin D and calcium reduced the risk of fractures in older persons, Vitamin D alone was not effective.
The authors found less evidence to support taking Vitamin D supplements for cancer prevention. And though some data suggest high doses of Vitamin D can reduce the risk for total cancer, more research is needed to be sure.
Vitamin D deficiency has been linked to many ailments, including hypertension, stroke, diabetes and heart failure. A second study reviewed research on the effects of supplemental Vitamin D on cardiovascular problems.
In that study, the results have been inconclusive or contradictory — again calling for more study on the topic.
