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.
