Taking a look at the details The task force used a process

studies are combined and analyzed together--to consider existing
research on vitamin D and calcium in relation to cancer and
fractures. Of the 137 studies selected for review, 16 randomized
controlled trials were deemed of sufficient quality to include
in the final analysis. Nearly all of the participants in these
16 studies were postmenopausal women, 65 years old and up. While

research to better understand the relationship between these
supplements and long-term effects on health, their finding of a
weak association between these supplements and bone protection
in postmenopausal women may point to the importance of knowing
whether a person is deficient before supplementing. Taking a
look at the big picture Older people living in care facilities
are more likely to be vitamin D deficient, so it makes sense
that providing them with
