Vitamin D may not ward off certain diseases

Does taking extra vitamin D help ward off different diseases? Researchers may be far from a good answer.

Two new studies shed more light on the so-called sunshine vitamins and leave behind more questions.

The research in the Annals of Internal Medicine found that vitamin D and calcium reduced the risk of fractures in older person.

But vitamin D alone was not effective.

Authors also found less evidence to support taking vitamin d supplements for cancer prevention.

And, while some data suggest high doses of D can deduce the risk for total cancer, more research is needed to be sure.

The second study tried to determine if vitamin D supplements had any impact on cardiovascular problems. Results were inconclusive, and contradictory, again calling for more study.
